| 摘 要： | 利用搅拌摩擦加工(FSP)制备纳、微米氧化铝颗粒单一增强以及混杂增强的A356铝基复合材料,并在摩擦磨损试验机上考察其磨损性能。结果表明,在0.5~3.0 MPa载荷范围内,在相同载荷下,混杂复合材料的磨损量都低于两种单一增强的复合材料;在不同载荷下,随着载荷的增加,复合材料的磨损量都增加,但是混杂颗粒增强复合材料的增加最快,微米颗粒增强复合材料最慢;复合材料的磨损机制主要是磨粒磨损和剥层磨损;在复合材料磨损亚表层都发现机械混合层的存在,对复合材料的耐磨性有一定的影响。

| Abstract: | Both particles of nanometer and micron Al2O3 reinforced A356 aluminum matrix composites were fabricated by friction stir processing,and their wear resistance properties were investigated on friction and wear tester.The results show that the wear loss of the hybrid composites is less than that of the composites reinforced with only nanometer alumina or micron alumina under load between 0.5 MPa to 3 MPa.As the load increases,the wear loss of the hybrid composites increases most rapidly among the three composi... |
