电流密度对CNTs-Ag-MoS2-G复合材料滑动电摩擦磨损性能的影响
Effect of Electric Current Intensity on Friction and Wear Properties of CNTs-Ag-MoS2-G Composites in Electrical Sliding Contact
摘要
Abstract
Electrical sliding contact materials are requested to have excellent anti-friction and electrical contact properties.In the area of aerospace,it is very important to produce advanced electrical contact composite materials.CNTs-Ag-MoS2-G composites used in the experiment were fabricated by means of powder metallurgy method.The contact resistance and wear volume loss of the composites in the electrical sliding wear were investigated,and the worn surfaces were observed by SEM as well.The resuits showed that the contact resistance decreased but the wear volume loss increased while the current intensity changed from 5A/cm2 to 15A/cm2.The wear volume loss of the positive brushes was larger than that of the negative brush because of the consequences of arcing,and also the wear volume loss of CNTs-Ag-MoS2-G composites was less than that of Ag-MoS2-G composites for the particular effect of carbon nanotubes on matrix reinforcement and electrical thermal conductivity.关键词
