| 摘 要： | 本文中考察了Ti3SiC2/Cu摩擦副在干摩擦和微量离子液体润滑条件下的载流摩擦学特性.在干摩擦条件下,Ti3SiC2/Cu摩擦副的摩擦系数值为0.6~0.75.当滑动速度从0.11增至0.33 m/s时,接触电阻降低小,在Ti3SiC2栓磨损表面有Cu的转移膜形成.当滑动速度为0.44和0.56 m/s时,栓/盘接触不稳定并且产生电火花,表明在机械磨损和电磨损共同作用下Ti3SiC2栓发生了严重磨损.在微量离子液体润滑条件下,Ti3SiC2/Cu摩擦副处于边界润滑状态,随着滑动速度的提高,摩擦系数由0.08增至0.2.当滑动速度高于0.33 m/s时,产生长约数厘米、平均直径53μm的弯曲缠绕的铜丝,这是相对较硬的Ti3SiC2对Cu盘犁削作用的结果.铜丝将离子液体"扫离"了摩擦表面,并且对摩擦学性能和电性能造成不利影响. |
| 关 键 词： | Ti3SiC2 离子液体 摩擦和磨损 电接触 |
