PVD Coated Carbide Grade Introduction
EDGEV PVD (Physical Vapor Deposition) coatings are manu-factured through using an arc evaporation processing, high evapo-ration on the surface of cemented carbide, and to be combined with the reaction gas in the controllable state, and deposited into a variety of different wear resistance film, all of coatings are used the composite single layer and multilayer nanostructures. Compared with the CVD film, the film is more uniform, to ensure a long life of cutting tools.
