About PVD Coating

Physical vapor deposition (PVD) is to deposit a thin film by the condensation of a vaporized form of certain material on working steel piece surface. And can get a high hardness layer with low COF and with some addtional resistance to high abrasion, high corrosion and high temperature. It's been used on screws for some optical situation or with fillers like glass fiber or halogen free additives.
