Ceramic PVD coatings
Ceramic PVD coatings are usually carbides, nitrides, borides and silicides of the IVth, Vth and VIth groups of the periodic table.

The most commonly used ceramic PVD coatings available are TiN, CrN, TiCN, TiAlN and CrAlN. The hardness, friction and wear resistance of these PVD ceramic coatings have been improved by the adding other elements such as vanadium, yttrium, chromium etc. and the deposition of multilayers and nanocomposite coatings.

Low friction coatings
Attention recently has focused on the development of hard, wear resistant, low friction coatings such as Graphit-iC™, MoST™, Dymon-iC™, Dylyn® and Diamonex. Components and tools are coated with these low friction coatings to reduce energy losses due to friction as their friction coefficients are much lower than those that can be achieved through conventional oil lubrication.
