The Benefits of PVD Coating on Electroplated Parts

Chrome plating technology is an underappreciated marvel of materials science—a fascinating alchemy of chemistry and metallurgy that produces the most well-known metal surface finish available. Chrome plating or chrome PVD coating, which was introduced in the 1920s, quickly gained popularity in the auto industry, consumer products, and then in the home with faucets and door hardware.

The Benefits of PVD Coating on Electroplated Parts

What’s Unique About Chrome Coating?

Before we get into how PVD can help chrome plating, it’s important to understand why this coating is unique. The first point to mention is that “chrome plating” is made up of two or three different metal layers, with only trace amounts of chromium present. The plating stack on most substrates, such as steel, zinc, and plastic, includes copper, nickel, and finally a top layer of chromium. When applied to brass, the copper is omitted, and the process begins with nickel and chromium.

Other materials can also be added to nickel baths to create an appealing matte or pearl-like texture.

A Thin But Significant Layer of Chromium

Despite the fact that the chromium layer is thin, the contributions are substantial. As far as pure metals go, it’s one of the hardest (1000HV), which, when built on top of a supporting structure of thick, moderately hard nickel (600HV), will increase toughness and durability even more. Chromium also has a strong naturally forming surface oxide layer that protects it from chemical attack and tarnishing, which is why chromium is used to make stainless steel alloys “stainless.”

A Serious Drawback: Strict Regulation of Chemical Plating Process

One disadvantage of chromium plating is the stringent regulations governing the chemicals used to create the coatings—not the metal layer itself, which is safe. Chrome plating is most commonly done with the hexavalent form of chromium (Cr6+). Over the last few decades, the plating industry has made great strides in improving these aspects, and the process has been adopted by many markets. However, the hexavalent approach remains the dominant approach. Please keep in mind that PVD coatings or PVD coating companies are one option for replacing hexavalent chrome with a more aesthetically pleasing appearance—but that is a topic for another post.

Chromium in Decorative Coatings—PVD on Electroplated Parts

Regardless of the type of chromium deposit used, both are completely compatible with the wide range of decorative PVD coatings offered by Vapor Technologies (VaporTech®). Parts that have been chrome plated typically require no additional treatment and can be placed directly into a coating system for a new finish. By incorporating a PVD system into their production line, manufacturers can add different colors to products that already have a chrome finish. These decorative PVD finishes are thin and conformal to surface features, allowing the parts to retain their texture – polished will remain polished, and matte will remain matte.

Our coatings engineers are knowledgeable about surface finishing techniques other than PVD, such as electroplating, powder coating, anodizing, and mass finishing. We are eager to collaborate with our customers to determine how these technologies can be combined to create new solutions.

6 Steps In The Manufacturing Process Of a Stainless Steel Product

Stainless steel is a metal that is widely used in modern construction. This alloy is widely used in the construction of decorative elements due to its corrosion resistance and pleasing appearance, particularly in areas with unfavorable atmospheric influences. Stainless steel is literally all around us and you can also use custom PVD coating.

stainless steel pvd coating services

Yet how many of us are familiar with the way this type of metal and its derivative products are made? There are six major steps in the production of stainless steel, according to this article:

Here Are 6 Steps In The Production of Stainless Steel

  1. Melting And Casting

The raw materials that make up a stainless steel item are combined and melted in a massive electric furnace. During this step, intense heat is applied repeatedly for 8 to 12 hours. When the melting process is finished, the molten steel is cast into the desired semi-finished forms. Slabs, blooms (rectangular shapes), billets (round or square), rods, and tube rounds are some of the most common forms or shapes.

  1. Forming

The semi-finished steel shapes go through a series of forming operations in the second stage. For example, stainless steel is hot rolled (heated and passed through enormous rolls) and PVD coating michigan. The aforementioned blooms and billets are converted to bar and wire. In contrast, slabs are formed into plates, strips, or sheets. As the most versatile stainless steel form, semi-finished steel shapes are frequently turned into bars (it comes in all grades and sizes). There are round, squared, octagonal, and hexagonal bars, each suitable for a specific application.

  1. Heat Treatment

During this step, the various stainless steel forms are thoroughly annealed. Annealing is another term for heat treatment that involves heating and cooling stainless steel in a controlled environment. The goal of this heat treatment is to release pent-up stress within the stainless steel and soften the material, making it more suitable for a wide range of applications. The people in charge of carrying out the annealing process must exercise extreme caution because even minor changes in temperature, pressure, duration, or cooling rate can result in a faulty product.

  1. Descaling

A certain amount of scale appears on the surface of the stainless steel during the annealing process. This scale can be removed through a variety of processes known collectively as descaling. Pickling is one of the more common ways to perform the descaling process.

  1. Cutting

In this step, the semi-finished, heat-treated, and descaled stainless steel forms are cut into specific shapes. Mechanical cutting is done using guillotine knives, blanking, nibbling, and high-speed blades.

  1. Finishing

Finishing is used to give the stainless steel product its distinctive aesthetically pleasing appearance. Finishing is also required to make the stainless steel product smooth and easy to clean, which is a must in sanitary applications.

Stainless Steel Fabrication And (re)passivation

Steel is delivered to construction companies and PVD coating companies craftspeople in a variety of forms, including bars, plates, and sheets. However, its installation and application in the manufacture of various products (for example, stainless steel tanks) generally necessitate additional fabrication and processing. When we think of stainless steel fabrication, we usually think of processes like cutting and welding.

Unfortunately, both treatments destroy the protective layer on the surface of the steel, significantly reducing its corrosion resistance.

Conclusion

In addition to steel’s traditional properties, stainless steel has corrosion and heat resistance. It has all of the benefits of steel plus a few of its own. It is less prone to corrosion, can withstand harsh environments better, and has a longer service life. It is not, however, completely stain-proof. To begin, corrosion resistance is grade dependent. However, abnormal environmental conditions such as low oxygen, poor circulation, and high salinity can permanently stain it.

Chrome Plating vs Stainless Steel: What is the Difference

When it comes to contrasting the two finishes of steel and stainless steel, there are several things to consider. While some people consider chrome plating to be a better choice for decorative finishes, stainless steel is often a better choice for everyday use. Both finish types are relatively inexpensive and not as heavy. However, some people choose stainless steel because of its nickel content, which makes it better than chrome-plating at preventing corrosion.

Chrome Plating

Stainless Steel

When it comes to corrosion resistance and durability, chrome plating is the clear winner. Whether it’s in a marine environment or an industrial setting, chrome plating can be a great choice. It is also much more affordable than stainless steel and offers plenty of durability. However, it’s important to remember that a good plating is not the same as a good stainless steel.

Chrome plating involves coating steel with chromium, a chemical element, to prevent rust. After the process, the steel metal becomes shiny and resistant to corrosion. But while chrome has a very appealing shine, stainless steel has a distinctly different look. Unlike chrome, stainless steel is an alloy made from steel and other elements.

Chrome Plating

When choosing between chrome plating and stainless steel, it is important to understand the differences between the two materials. Both can be useful for a variety of purposes, including industrial and decorative purposes. Both have high lustre and are resistant to abrasion. If you need a bright, durable finish for your products, chrome is a good option. Chrome is also lighter weight than stainless steel, making it easy to move and rearrange your furniture.

When deciding whether stainless steel or chrome plating is best for your project, you should consider the price of the materials. Stainless steel is usually less expensive than chrome, so you can save money by going with chrome plating. However, this is not always the best choice for your application. If you’re worried about corrosion or spot rust caused by atmospheric pollution, you might want to opt for stainless steel.

Elctro-Polishing

Electropolishing is a process that can be used to create an excellent decorative finish on chrome plated and stainless steel parts. The process not only creates an attractive look, but also increases corrosion resistance. It does this by reducing the surface area, eliminating occlusions, and reducing free iron and chromium content. Electropolishing also creates a passivating layer of corrosion-resistant chromium oxide. This is important for certain applications, such as pharmaceuticals, semiconductors, and medical equipment. The oxide layer has little to no tendency to react with the liquid or gaseous environment and provides a non-corrosive surface for many types of components.

Electropolishing is a popular choice for products that need to resist corrosion. The process requires only a minimal amount of manual labor. It is an efficient way to give a product a brilliant, high-quality surface. The process produces corrosion-resistant polished stainless steel items quickly and at high-speed.

Elctro-Polishing vs Chrome Plating

Electro-polishing is a process for applying a shiny finish to stainless steel parts. It produces a reflective surface but the bare base metal can corrode if it is not protected. Many automotive trim pieces feature electro-polished, glossy stainless steel. However, this process does not achieve the Cr/Fe ratio that is necessary for corrosion resistance. Some automotive manufacturers also apply a chrome flash to their products in order to harmonize their products with chromium-plated carbon steel.

Electro-polishing has advantages over chrome plating for some applications. It is more affordable and accessible than chrome plating, and can produce a chrome-like finish that is similar to that of chrome. It is also suitable for delicate parts.

Stainless Steel vs Chrome Plating

While many manufacturers still rely on traditional materials and processes, there are several alternative metal finishing techniques that can improve your products. Chrome plating is one such method. In this article, we compare the advantages of both types of metal finishing. In addition to enhancing corrosion resistance, chrome plating also adds a distinctive shiny appearance to a product.

Chrome is more attractive than stainless steel and is perfect for many decorative applications. However, if you’re looking for a long-lasting and durable metal surface, stainless steel will be your best choice. It will last much longer than chrome and will not dent easily when put under heavy use.

SurfTech INC is an Ohio-based surface technologies company. Its core product is a nanotechnology thin film coating called SurfTech 3012. The coating can extend the life of blades and cutting tools in the food processing industry, and it outperforms traditional Titanium Nitride coatings.

How Much Does PVD Coating Cost?

PVD which is an acronym for physical vapor deposition is a wonderful technique for giving a proper coating on surfaces. There are a lot of industries such as medicine, automobile, and other manufacturing units which highly prefer the physical vapor deposition process. Everyone loves the aesthetic finish of the thin film which also provides incredible durability and the services for the same are usually outsourced. But there is often a question about how much will the cost of PVD coating be if the coating has to be done in an in-house product. There are a lot of manufacturers who will bring up different price quotations when it comes to the physical vapor deposition process.

We at SurfTech INC are one of the best PVD coating companies that provide the best solution for the process at the best prices. We have got a team of experts who keep a detailed knowledge of the marketplace so they would provide premium results at the best prices.  Let us further look at some of the frequent questions that usually pop up when we talk about physical vapor deposition.

  • What all the consumables that are used in the parts would cost and what would be an overall estimate?
  • Another common question is about the throughput of parts in a typical PVD setup. Also, a lot of inquiries generate about the total number of parts in a batch and how long will one batch take to be processed.
  • Based on all the information, what will be the eventual PVD coating cost per part?

Per-Part PVD Coating Costs

When we talk about the process involved in the coating, there are vertical racks and fixtures where all the parts are carefully placed and eventually loaded into a chamber where they are further processed. There are varied sized of equipment required which are carefully used by the skilled professionals for the best outcomes.

Calculating PVD Coating Cost

We will be considering the cost of a 3d part whose measure on the biggest side is less than 6 inches. If we wish to have a durable and aesthetic finish on every part of the surface then we will easily be able to load at least 16 parts per rack. Its capacity of it could differ according to how large or small the part is.

Estimated PVD Cost-Per-Part

So a small PVD system with 6 parts in the rack would come at an estimated cost of about $14.the medium-sized PVD system with 10 parts of the rack would cost about $16 per batch. The large-sized 16 parts system would cost about $22 per batch. If you wish to have good durable coating finishes then a typical batch would take a maximum of 1 to 2 hours. Though if you wish to run multiple batches in a single shift then it would more of a performance wear coating which would take about 2 to 3 hours? There are some specific factors like good quality, enhanced efficiency, and price costing that act as important indicators for making the right decision about in-house PVD coating.

Surftech Inc is one of the best Pvd coating companies and our team is always ready to help you with the best prices and perfect outcomes.

Different Types of Pvd Coating

PVD which is an acronym for physical vapor deposition can be determined as a process that includes the vaporization of a metal material which is then condensed to the surface of the production part in form of a coating. The quality of these production parts increases significantly as the physical vapor deposition or the PVD coating process enhances the durability, and toughness of the product and makes it oxidation and chemically resistant.  There are a lot of industries namely, automotive, medical industry, and aerospace which use this process time and time again. This helps to improve the overall performance of the product and brings a lot of comfort in terms of ease of cleaning. Let us further look at the three popular types of PVD coating

Three Main Types of PVD Coating

This incredible technique of physical vapor deposition first came into prominence during the early period of 1970s. They picked up a great pace in terms of usage in the late 90s and were essentially being used by every major industry. There are several processes of the PVD which are covering a large spectrum of work with super incredible attributes. Vapor deposition, sputter deposition, and thermal evaporation though are three of the popular and commonly used forms. Each of the processes in the PVD coating has got its subsets but they all are providing incredible results.

  • Thermal Evaporation

Thermal evaporation is divided into two main categories, one is electron beam deposition and the other is pulsed laser deposition. Both of these processes take the help of energy in evaporating any material such as chromium, aluminum, copper, or titanium in the vacuum. Now the vapor through the vacuum enters the production parts which are comparatively cooler where they get a chance to condense to take the formation of the hardened metal state. The process of thermal evaporation is mostly used in micro fabrication, packaging, and the computer industry.

  • Sputter Deposition

Magnetron sputtering and ion beam sputtering are the two different type of deposition that is being used in manufacturing applications these days. The process of the ion beam is used to navigate a high electric field towards the material’s surface to vaporize. This led to the ionization of metal vapor gases directing the moment of ions towards the part of the production. Magnetron sputtering though is slightly different where the charged ions get the required acceleration by the electrical field which is then superimposed to targeted directions. The medical industry highly prefers to use this process.

  • Arc Vapor Deposition

The most popular PVD plating process which is highly preferred by Surftech Inc is arc vapor deposition. The process involves the usage of a low-volt arc to vaporize the surface of the metal. Now the evaporated atoms of the metal start to combine with molecules of the gas and again the process of condensation starts in cooler production parts situated nearby. a multi-axis carousel help to spin the parts in production and distribute them in equal quantity for perfect coating. This process has come into prominence because it is one of the most environmentally friendly processes.

Surftech INC has years of experience in dealing with PVD coating as well PVD plating process. Our team will be all thrilled to help you understand the various processes and suggest what will suit best for you.

PVD Coating Advantages

One of the most popular coating techniques at present is PVD which is an acronym for physical vapor deposition. It is mostly used for jewelry, car, watch, etc. there are a lot of PVD coating advantages that makes it preferable when it comes to coating. But before we discuss the advantages it is important to know what exactly physical vapor deposition is.

People often confuse physical vapor deposition with chemical vapor deposition but there is a big difference between the two. The physical vapor deposition involves the use of argon gas. The ions of the argon are bombarded at a specific target which creates a film at the surface. Because there is residue released, it is regarded as a physical process. There are a lot of PVD coating companies that work with this process as it is largely accurate and give wonderful results. Let us further understand some of the basic principles of physical vapor deposition which are essentially divided into three major steps.

  1. The first part includes the gasification of the material to be plated. This means that the material would be evaporated or sputtered as per the requirement.
  2. Once the collision of molecules atoms and ions initiates, there happens a variety of reactions which are known as migration.
  3. Finally, there happens the placement of molecules, ions, and atoms on the substrate.

Let us now understand the specific PVD coating advantages which make it a preferable product over any other products:

  • Good Durability

One of the most important aspects of using physical vapor deposition is because of the durability it ensures and eventually provides. This is mainly because when we compare the process to any other method, physical vapor depositions provide much more hardness and are largely resistant to any sort of corrosion. Being anti-corrosion also plays an essential role in being used as the most preferred process.

  • Wide Application

It is important to understand nearly all the materials whether it is organic or inorganic could be used using a different types of finishes on the group of substrates

  • Environment Friendly

People these days give a special preference to the product which are made without impacting the environment in any wrong way. Physical vapor deposition is performed in a vacuum environment and therefore is much more eco-friendly than any other techniques used. It is also important to know that the process does not release any lethal gases such as SO2 OR CO which are very harmful to the environment.

  • Convenient Cleaning

The PVD films are pretty easy to clean. Any other material takes a lot of time and effort to clean the product. But you only need a glass cleaner or a simple piece of soft cloth to clean the PVD film.

  • High Quality And Multiple Choices

The wide variety of colors that the PVD film provides to choose from makes it a strong contender against its counterparts. It gives a pretty smooth and fine texture to the surface which makes it a very popular process in the market.

Surftech INC is one of the best PVD coating companies. Our team would be happy to help and let you know more about the process.
