采用粉末注射成形技术制备SiCP/Cu复合材料零件,研究了该复合材料的粉末注射成形工艺过程,获得了理想SiCP/Cu复合材料注射成形零件,并对该复合材料进行摩擦磨损试验。结果表明,SiCP的加入改善了材料的摩擦学性能,摩擦系数随滑动时间的延长而增加得较为平缓;含10%SiCP的复合材料磨损表面的粘着和塑性变形程度轻,有一定的磨粒磨损;含15%SiCP的该复合材料磨损表面呈典型磨粒磨损;该复合材料磨损表面存在白亮色的致密机械混合层,同时磨损试验的偶件40Cr钢环表面也被犁削而形成了平行的条纹;该复合材料磨损表面含有Cu、Si、C、Fe和O元素,这增加了钢环表面转移过来的Fe元素和表面摩擦发热造成的氧化而带来的O元素。
SiCP / Cu composite parts were prepared by powder injection molding. The powder injection molding process of the composite was studied. The ideal SiCP / Cu composite injection molding parts were obtained, and the friction and wear tests of the composite were carried out. The results show that the addition of SiCP improves the tribological properties of the material, and the friction coefficient increases more smoothly with the increase of sliding time. The adhesion and plastic deformation of the wear surface of the composite with 10% SiCP are light, and there is a certain abrasive wear ; The wear surface of the composite with 15% SiCP shows the typical abrasive wear; the white bright color of the dense mechanical mixed layer exists on the wear surface of the composite material, and the surface of the 40Cr steel ring of the even wear test is plowed to form a parallel The wear surface of the composite material contains Cu, Si, C, Fe and O elements, which increase the O element brought by the oxidation of the Fe element transferred from the surface of the steel ring and the surface friction heat.
