Physical vapor deposition is a fairly simple process that involves various substance changes.

The process of physical vapor deposition is essentially created by a group of surface coating technologies that are used for a variety of purposes that include: tool coating, aesthetic, and equipment coating. Additionally, this process involves vaporization coating which utilizes atoms in a type of material transfer from solid to vapor, and then back to the solid phase. Eventually, the resulting material ends up with a film being created on top of the surface.

When it comes to reactive deposition, the material that’s being deposited reacts with an environment that’s primarily gaseous and also filled with co-deposited materials to form a compound material film – i.e. carbide, oxide, etc.

PVD coating can be done in several ways, but there are three basic categories that include: ion plating, evaporation, and sputtering. These three processes all use the same fundamental steps to create the coating. Now, they may use the same fundamental steps, but they generate and deposit material differently, requiring unique equipment pieces catered to each process.

Fundamental Steps

The first fundamental step involves a vapor phase from the coating material through sputtering, evaporation, chemical vapors, etc. The second step involves the transfer of vapor from source to substrate. Finally, the last state involves the film growth and deposition on the substrate.

One example of a PVD process is the creation of medical device coatings. Certain equipment pieces like catheters require there to be a coating to minimize the risk of blood clots, infection, and rejection. These coatings are produced over the catheters and kept in a sterile condition, as to reduce the chances of any bacteria entering the body on use.
