Abstract This investigation evaluates the lubricities of Trihexyltetradecylphosphonium dicyanamide and Trihexyltetradecylphosphonium tricyanomethanide and discusses the tribo-decomposition behavior using quadrupole mass spectrometer (Q-MS). This investigation focused on the ability of these ionic liquids to be used as novel lubricant oils and lubricant additives. Both ionic liquids exhibited better lubricities compared to conventional ionic liquids. Q-MS analysis indicated that both ionic liquids underwent tribo-decomposition on worn surfaces. The substances derived from cation were identified immediately after the friction test was initiated. Tribo-film was composed with cations and anions and the surface analysis undertaken following the friction tests found it to be rich in anions. This study indicates that these ionic liquids may be suitable for application as lubricant additives.

使用四极杆质谱仪原位观察由鏻阳离子和氰基阴离子组成的离子液体的摩擦分解行为

摘要 本研究评估了三己基十四烷基鏻二氰胺和三己基十四烷基三氰基鏻的润滑性，并讨论了使用四极杆质谱仪 (Q-MS) 的摩擦分解行为。这项研究的重点是这些离子液体用作新型润滑油和润滑油添加剂的能力。与传统离子液体相比，两种离子液体都表现出更好的润滑性。Q-MS 分析表明两种离子液体在磨损表面上都发生了摩擦分解。在摩擦试验开始后立即鉴定出源自阳离子的物质。摩擦膜由阳离子和阴离子组成，摩擦测试后进行的表面分析发现它富含阴离子。
