摘　　要：利用PCVD复合渗镀技术对W6Mo5Cr4VZ(MZ)高速钢刀具进行表面强化处理,研究PCVD复合渗镀处理前后高速钢刀具的表面硬度、摩擦磨损性能和抗氧化性能。结果表明,经PCVD复合渗镀处理后,W6Mo5Cr4VZ(MZ)高速钢刀具的表面硬度明显提高,磨损性能大幅改善。表面强化层优异的抗氧化能力和强韧性提高了刀具的切削性能。The surface hardness, wear resistance and oxidation resistance of the composite diffusion strengthening coatings on high speed steel tool by PCVD were studied. The results show that the surface hardness and wear resistance of the W6Mo5Cr4VZ（MZ） high speed steel tool after PCVD increase obviously. The machinability of the tool is improved due to the excellent oxidation resistance and obdurability of the surface strengthening layer.
