DLC-Coating consists of nano-crystalized carbon layers that are nearly unmatched in hardness, smoothness and wear-resistance. These layers (DLC = diamond-like carbon) have been originally developed for applications in professional automobile racing, such as to minimize wear and friction. As the name implies, DLC offers some of the outstanding qualities of natural diamond. These are used by KRYPTON to make surfaces chemically and abrasion resistant. Moreover, the biocompatible coating gives us an extreme hardness of up to 4,000 Vickers. Thereby the surfaces get more than ten times harder.
