Abstract

Abstract

3Cr2W8V die was surface modified by adding different contents of V-Ti solid solution reinforced phase in the laser cladding powder,and the wear resistance and thermal fatigue properties of the modified die were tested and analyzed.The results show that adding V-Ti solid solution could improve the wear resistance and thermal fatigue properties of the surface modified die.The optimized content of V-Ti solid solution is 15%.Compared with those of the die without V-Ti solid solution in the laser cladding powder,the wear volume of the surface modified die decreases by 63%,and its thermal fatigue crack level changes from 7 to 2.
