| 摘 要： | 研究了用超声波加工技术对HAP/SiC复合生物陶瓷材料进行加工时晶须取向对加工机理、材料去除率和加工表面粗糙度的影响。研究结果表明材料去除率和加工表面粗糙度随晶须方向角的增大而增大。在相同的加工条件下 ,材料的断裂韧性越高 ,其MMR越小。该研究为HAP/SiCw复合生物陶瓷材料的超声波加工提供了工艺依据

| Abstract: | The influence of whisker orientation on machining mechanism, material removal rate and roughness of finished surface when machining the HAP/SiC w composite bioceramics material by using ultrasonic machining technology is studied. The results show that material removal rate and roughness of finished surface will increase with the increase of the direction angle θ?Under the same machining condition, the higher is the fracture toughness of the material, the lower is the material removal rate. This fact provides technological basis for the ultrasonic machining of HAP/SiC w composite bioceramics material. |
