【摘要】：用腐蝕性較低、簡(jiǎn)單易合成的磷酸酯離子液體為基礎(chǔ)油,聚四氟乙烯微粉為稠化劑制備一種新型的離子液體潤(rùn)滑脂,在Optimol SRV摩擦試驗(yàn)機(jī)上考察其對(duì)鋼/鋼摩擦副的摩擦學(xué)性能。結(jié)果表明,磷酸酯離子液體潤(rùn)滑脂在室溫和高溫(100℃)下都表現(xiàn)出優(yōu)異的減摩抗磨性,并且其減摩抗磨性與離子液體陽離子和陰離子的烷基鏈長(zhǎng)密切相關(guān)。磨斑表面掃描電鏡和XPS的分析結(jié)果表明:摩擦表面既存在離子液體潤(rùn)滑脂與摩擦表面發(fā)生摩擦化學(xué)反應(yīng)生成的含有Fe F2、Fe PO4和氮的氧化物的化學(xué)反應(yīng)膜,又存在稠化劑聚四氟乙烯的物理吸附膜。
[Abstract]:A new type of ionic liquid grease was prepared by using simple and easy synthetic phosphate ionic liquid as base oil and polytetrafluoroethylene powder as thickener. The tribological properties of the grease on steel / steel friction pair were investigated by Optimol SRV friction tester. The results show that phosphate ionic liquid grease exhibits excellent antifriction and antiwear properties at room temperature and high temperature (100 鈩，
