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.

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.

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.
