| Abstract: | Sintering process of P/M YG20C cemented carbide was optimized by the orthogonal test.Cemented carbide was prepared by the optimal sintering process and the influence of sintering temperature,sintering time,and sintering pressure on properties of the material was analysed.The results show that fine and uniform grains of WC distribute on Co matrix,the relative density and hardness of YG20C cemented carbide are 99.4% and 89.2HRA after sintering with 1 070 ℃×15 min×60 MPa.The hardness increases by 2-3HRA compared with traditional vacuum sintering process. |
