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.
