摘要
通过多弧离子镀技术在铜基体上制备了TiN及其掺杂原子分数10%和12%铜的涂层,用1-辛基-3-甲基咪唑双(三氟甲烷磺酰)亚胺盐(OMImNTf_(2))和1-十二烷基-3-甲基咪唑双(三氟甲烷磺酰)亚胺盐(C_(12)MImNTf_(2))2种离子液作为润滑剂,研究了涂层与离子液组成的复合润滑体系对不同电压(0.5,1 V)下铜/铜摩擦副的载流摩擦学性能的影响。结果表明:在电压相同条件下,TiN涂层与OMImNTf_(2)复合润滑体系具有较好的协同润滑效果,TiN涂层与C_(12)MImNTf_(2)复合润滑体系具有较好的导电性能;在掺铜TiN涂层和2种离子液复合润滑体系下摩擦副的摩擦因数和接触电阻差别很小。当电压由0.5 V增大到1 V时,在TiN涂层、掺杂原子分数10%铜的TiN涂层与C_(12)MImNTf_(2)组成的复合润滑体系下摩擦副的摩擦学性能更稳定。掺杂原子分数12%铜的TiN涂层的摩擦副具有最小的摩擦因数和接触电阻。
TiN coating and TiN coatings doped with 10%and 20%(atom fraction)copper were prepared on copper substrate by multi arc ion plating.Using 1-octyl-3-methylimidazole double(trifluoromethane sulfonyl)imide salt(OMImNTf_(2))and 1-dodecyl-3-methylimidazole double(trifluoromethane sulfonyl)imide salt(C_(12)MImNTf_(2))as the lubricant,the effect of coating and ionic liquid composite lubrication system on current-carrying tribological properties of copper/copper friction pair at different voltages(0.5,1 V)were studied.The results show that the TiN coating/OMImNTf_(2) composite lubrication system showed relatively good synergistic lubrication effect at the same voltage,while the TiN coating/C_(12)MImNTf_(2) composite lubrication system exhibited relatively good conductivity property.The difference of friction coefficient and contact resistance of friction pair under composite lubrication system of copper-doped TiN coating and two ionic liquids was very small.When the voltage increased from 0.5 V to 1 V,the tribological properties of friction pair under composite lubrication system consisted of TiN coating,TiN coating doped with 10%copper and C_(12)MImNTf_(2) was more stable.The friction pair containing TiN coating doped with 12%copper had the smallest friction coefficient and contact resistance.
