PVD coating is a plasma coating deposition technology which the materials are vaporized under vacuum conditions ,so as to avoid the reaction between the vaporized material and air.  PVD coating is used to add new features as improve the workpieces' hardness,wear resisitance,corrosion resisitance ect..
 coating thickness            0.5-10μm
 hardness                        1000-4000 HV
 temperature resisitance    300-1150°c
 deposition temperature     200-600°c
