Abstract
In order to prepare heatresistant inner layer of hotforging die plasma spraying plasma remelting and plasma spray welding were adopted Cr3C2 coatings of NiBased were prepared respectively with 10 20 and 30 Cr3C2 powder and W6Mo5Cr4V2 substrate The coating microstructure analysis the microhardness test and the measurement of thermal parameters of coating were conducted The experimental results show that the coating has the better thermophysical property by using plasma spray welding method with the powder ratio of 90 Ni60 and 10 Cr3C2 and by this way the microhardness of coating can achieve 1100 HV
