为了了解润滑剂在摩擦界面的电渗效应，采用四球摩擦磨损试验机研究了水性润滑剂和含有电渗促进剂3-[（3-胆酰胺丙基）-二甲基铵]-1-丙磺酸盐（CHAPS）和电渗抑制剂十六烷基三甲基溴化铵（CTAB）的SiO2纳米润滑剂的摩擦学特性.结果表明，CHAPS润滑剂使摩擦系数和磨痕直径减小，而CTAB润滑剂表现出相反的行为。钢/陶瓷接触下的摩擦学性能的变化比钢/钢接触下的摩擦学性能的变化更显著。磨损表面分析表明，SiO2基的摩擦膜形成与CHAPS纳米润滑剂，而摩擦膜几乎没有观察到与CTAB纳米润滑剂。这是由于在摩擦界面处形成的自激电场引起的毛细电渗效应影响了润滑剂的渗透性。
To understand the electroosmosis effect of lubricants at friction interfaces, the tribological characteristics of aqueous lubricants and SiO2nanolubricants containing an electroosmotic promoter, 3-[(3-cholamidopropyl)-dimethylammonio]-1-propanesulfonate (CHAPS), and an electroosmotic suppressant, cetyltrimethylammonium bromide (CTAB), were examined using a four-ball tribometer. The results show that CHAPS lubricants produce reductions in the friction coefficient and wear scar diameter, whereas CTAB lubricants exhibit the opposite behavior. The variation in tribological performance under a steel/ceramic contact is more significant than that under a steel/steel contact. A worn surface analysis indicates that a SiO2-based tribofilm is formed with CHAPS nanolubricants, whereas the tribofilm is hardly observed with CTAB nanolubricants. This is attributed to the capillary electroosmosis effect induced by the self-excited electric field formed at friction interfaces, which affects the penetrability of lubricants.
