BRIEF INTRODUCTION
Cutting tools surface coating, which improves cutting speed and feed speed then cutting efficiency and cutting tools using life by enhancing cutting tool surface hardness,heat stability and lowering friction coefficient.
COATING TECHNOLOGY
Magnetron sputtering deposition coating means under plasma condition, Ar gasis ionized into positive ions to bombard target surface to create target particles and deposit on substrate surface to form a film.
Cathodic arc evaporation means under certain condition, metal evaporation source (target source) as cathode, by arc discharging with anode shell, target material is vaporized and ionized, forming a space plasma and depositing on workpiece to form a film.
