Keywords： W6Mo5Cr4V2

In order to prepare heat-resistant inner layer of hot-forging die,plasma spraying,plasma remelting and plasma spray welding were adopted.Cr3C2 coatings of Ni-Based were prepared respectively with 10％,20％ and 30％ Cr3C2 powder and W6Mo5Cr4V2 substrate.The coating microstructure analysis,the micro-hardness test,and the measurement of thermal parameters of coating were conducted.The experimental results show that the coating has the better thermo-physical property by using plasma spray welding method with the powder ratio of 90％ Ni60 and 10％ Cr3C2,and by this way the micro-hardness of coating can achieve 1100 HV.
