Abstract :
In order to satisfy performance and long life requirements for hot forging die, Ni60-SiC cermet coating was prepared on the high speed steel W6M05Cr4V2 by plasma cladding technology. Metallurgical bonding coating with enough bonding strength was obtained after optimizing the cladding parameters. The clad coating composition, microstructure, microhardness and thermal physical parameters were analyzed by X-ray diffractometer (XRD), optical microscopy (OPM), microhardness tester, laser thermal constant tester and dynamic thermo-mechanical analysis. The experimental results show that Ni60-SiC cermet coating can greatly improve the hardness of hot forging die surface, and reduce the thermal stress of hot forging die surface. Cladding coating has a very good performance of thermal properties.
