Abstract The VC coating was prepared on the surface of the M35 screw punch by thermal reaction diffusion technique, but it was found that the matrix was cracked by the conventional martensite quenching method. The microstructure, element distribution and hardness of the materials were measured using metallographic microscope, scanning electron microscope and Vickers hardness tester. The causes of cracks and the adjustment of the process were studied. The results show that, during the thermal reaction diffusion process, interdiffusion layers with high content of vana-dium elements are formed near the interface. Ms point of the steel will reduce with high vanadium element content in the interdiffusion layer. Du-ring the quenching process, the inner layer preferentially undergoes martensitic transformation with volume expansion, this process will cause tensile stress on the interdiffusion layer to crack it. Isothermal quenching was used instead of martensitic quenching, and effectively solve the problem of cracking by regulating tissue and relieving volume effects. The bainite austempering and three tempering processes can obtain M35 screw punch products with satisfactory mechanical properties and stable quality of VC coatings.
