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.
