Cermet body metal or hard coated and method for coating the cermet substrate body or metal hardness

摘要

The present invention relates to a method for coating by PVD cermet substrate body or hard metal. Without intermediate processing another, prior to PVD coating, using blast means of the particle, the area close to the surface of the substrate body, the substrate body that has finished the sintering, PVD layer only in this case or is blasted using a blast of granular means to have an intrinsic stress of approximately the same magnitude at least to the intrinsic stress of the PVD layer first. The present invention relates to cermet bodies hard metal or cermet body or hard metal, in the shape of a cutting tool in particular coated in this way more.
