| 摘 要： | 用钢/铝合金摩擦副在M-200环块试验机上进行摩擦磨损试验,研究纳米SiC微粒作为润滑油添加剂对润滑油润滑性的影响。用扫描电子显微镜观察摩擦块的磨损表面形貌,结果表明:高载荷条件下(大于700N),纳米SiC微粒的添加显著降低了钢/铝合金摩擦副的磨损量和摩擦系数;纳米微粒添加量为0.3wt%,润滑油的润滑性最好。

| Abstract: | The effect of SiC nanoparticales as additives on the antiwear ability and load-carrying capacity of lubricating oil for aluminum-on-steel contact was investigated on M-200 model friction and wear testing machine.Wear surface topography was characterized by SEM(scanning election microanalyzes).The results shows that the wearing value and friction coefficient was reduced with SiC nanoparticles added in aluminum-on-steel contact in high load(higher than 700 N);The lubricating ability is the best when the concentration of nanoparticales is 0.3wt%. |
