Abstract: With YG10 cemented carbide as the research object and cryogenic treatment technology as the methods,the specimens were treated at different cryogenic temperature,cryogenic holding time and alternating times by orthogonal test,and the treated specimens were subjected to wear test,hardness test and microstructure analysis test.The results show that the microhardness is increased by 33.6%,the wear resistance is increased by 72.8% after the optimal cryogenic treatment,and the cryogenic temperature is the biggest factor affecting the wear resistance of YG10 cemented carbide.The reasons for this phenomenon are as follows:in terms of microstructure,the dispersive distribution of η phase and the density change of Co phase enhance the wear resistance of cemented carbide.

Key words: cemented carbide, cryogenic treatment, wear resistance, microhardness, worn topography
