| 摘 要： | 采用真空热压烧结工艺制备含SiC颗粒体积分数为10%、20%、30%和40%的SiCp/ZL101A复合材料,研究普通磨削与超声纵向振动磨削SiCp/ZL101A复合材料时的SiC颗粒去除机制,并探索不同磨削方式对工件表面微观形貌、表面粗糙度的影响。结果表明:在相同磨削参数下,超声纵向振动磨削表面的粗糙度低于普通磨削表面的粗糙度;无论是超声纵向振动磨削还是普通磨削,SiCp/ZL101A复合材料的表面粗糙度均随着增强体SiC颗粒体积分数的增大而增大。

| Abstract: | SiCp/ZL101A composites were prepared by hot-pressed sintering process(HPS).The volume fraction of SiC particles was 10%,20%,30% and 40% respectively.The SiC particle removal mechanisms of SiCp/ZL101A with ordinary grinding and ultrasonic longitudinal vibration grinding were investigated.Moreover,the influence of different grinding types on surface microstructure,surface roughness of SiCp/ZL101A was studied.Results show that surface roughness and quality of ultrasonic grinding are better than that of ordinary grinding under the same grinding parameter.Grinding surface roughness of SiCp/ZL101A composites increases with the volume fraction increasing of SiC particles ultrasonic grinding and ordinary grinding. |
