PVD-coating (Physical Vapor Deposition) is a very modern technique that can be used, among other things, on parts of a cutlery set. This process uses condensation of atoms or molecules from a gas or vapor. This creates a wafer-thin layer that is only one to three micrometers thick. This layer increases corrosion and scratch resistance, but it also has visual benefits. For example, a black, gold or anthracite color can be imparted to stainless steel products.
