Abstract In the presence of flooded imidazolium hexafluorophosphate (LP108), Ag-Cu/Ti film prepared by multi-arc ion plating is well lubricated but severely corroded due to electrochemical corrosion even by using benzotriazole as a corrosion inhibitor. Although imidazolium methyltributylammomiumbis ((trifluoromethyl)sulfonyl)imide ([HEMIM]NTf2) is much less corrosive to Ag-Cu/Ti film, its lubricity is inferior to that of LP108. Preapplied LP108 on top of Ag-Cu/Ti film by dipping and withdrawing from 0.2 vol% LP108-ethanol solutions exhibits comparable lubricity as flooded LP108, and comparable corrosion as flooded [HEMIM]NTf2. The localized liquid LP108 around spherical and top-flat droplets of Ag-Cu/Ti film gives birth to in-situ hybrid Ag-LP108 tribo-layer upon sliding contact. Meanwhile, tribochemical affinity between PF6 anion and tribo-surface is another reason for good lubricity.

滑动电接触下多弧离子镀Ag-Cu/Ti膜上的坚固润滑和低腐蚀性咪唑鎓六氟磷酸盐润滑剂

摘要 在水淹六氟磷酸咪唑鎓（LP108）存在下，多弧离子镀制备的Ag-Cu/Ti薄膜润滑良好，但即使使用苯并三唑作为缓蚀剂，也会由于电化学腐蚀而严重腐蚀。尽管咪唑鎓甲基三基铵双（（三氟甲基）磺酰基）亚胺（[HEMIM]NTf2）对Ag-Cu/Ti薄膜的腐蚀性小得多，但其润滑性不如LP108。通过从 0.2 vol% LP108-乙醇溶液中浸渍和取出，将 LP108 预涂在 Ag-Cu/Ti 膜上，表现出与满液 LP108 相当的润滑性，以及与满液 [HEMIM]NTf2 相当的腐蚀性。Ag-Cu/Ti 膜的球形和顶部平坦液滴周围的局部液体 LP108 在滑动接触时产生原位混合 Ag-LP108 摩擦层。同时，
