The Durability of PVD Coating
Updated: Jun 19, 2020
When it comes to the world of metals and polishing, one of the things that we encounter often is PVD coatings. PVD coating is used in a wide variety of industries and has innumerable applications. One of the questions that is often asked about PVD is regarding its durability - is PVD coating durable? In this article, we address this question.
What is PVD Coating?
PVD is the abbreviation for Physical Vapor Deposition. PVD coating is used to refer to a host of thin film deposition techniques in which there is a solid material that is vaporized in a vacuum environment and then deposited on substrates as a pure material or alloy composition coating. PVD coating is extremely useful because it contributes to many performance attributes for a variety of products: semiconductor devices, solar panels, microchips, durable protective films, optical lens, and numerous medical devices. Therefore, PVD coatings can be found in lots of different industries. For example, in device applications such as computer chips or in optical applications like self-cleaning tinted windows or eye glasses. It can be used for decorative as well as functional finishes. PVD is the solution when a coating needs to be extremely thin, durable, pure, or clean.
Are PVD coatings durable?
PVD coatings are extremely durable. In fact, it would not be wrong to say that PVD is the most durable coating available in the market by far. The quality of PVD coatings is so superior that it is bound to outlast any other traditional type of finish. They are also highly resistant to corrosion and scratches.
In the process of PVD coatings, the coating material is transferred at a single atom or at a molecular level. This means that PVD coatings allow a very high level of control over density, structure, and stoichiometry of the films. With the help of specific processes and materials, it is possible to develop those attributes that are specifically desired of the physical vapor deposited film such as adhesion, lubricity, or hardness. These coatings help in the reduction of friction and also serve as a barrier against any possible damage.
