Abstract

To study the effects of PCVD combined nitriding coating processing on cutting performance of high speed steel tool, the PCVD was performed on W6Mo5Cr4VZ (MZ) steel tools to get surface strengthening, tool surface micro-hardness before and after PCVD process was studied, wear property and bonding force both before and after PCVD was analyzed, observed the PCVD impacts on antioxidant property. SEM was used to analyze PCVD area and substrate of the tools. The results show that (MZ) high speed steel tool micro-hardness improved obviously, wear property improves as well. The good antioxidant ability in the PCVD layer provides great cutting property to tools, SEM found that sample treated by PCVD have smooth fracture morphology, in which substrate and PCVD layer is clear.
