What is DLC coating?

DLC (diamond like carbon) is a surface coating consisting of a metal layer of chromium nitride, which provides a high surface hardness, coated with a layer of highly cristalline carbon, which provides to the surface exceptional tribological properties.

About fluorination

Direct fluoridation of DLC results in a chemical modification of the upper carbon layer thicknes, which significantly lowers the surface energy of the coating, while maintaining its hardness and friction properties.
