| 摘 要： | 以异辛基乙二胺-CF3SO3HEtHex(TFS)]型质子化离子液体作为钢/钢摩擦副的润滑油添加剂, 考察了不同HEtHex(TFS)含量的液体石蜡(LP)在不同温度和载荷下的摩擦学性能. 通过扫描电子显微镜和X射线能谱仪对钢球表面磨斑的形貌及所含元素进行了分析与表征. 结果表明, 加入HEtHex(TFS)添加剂可明显增大LP的最大无卡咬负荷(PB)值, 改善LP的减摩抗磨性能. HEtHex(TFS)在LP中添加的最佳质量分数为0.75%, 在25 ℃, 294 N时其减摩效果最好; 在25 ℃, 196 N时其抗磨效果最佳. 元素分析结果表明, 加入HEtHex(TFS)添加剂后在钢球表面形成了一层摩擦保护膜, 从而起到了减摩抗磨的作用.

| Abstract: | Tribological behavior of HEtHex(TFS) as additive in liquid paraffin(LP, simulant of lubricating base oils) with different mass fractions for the contact of steel/steel ball was investigated. At the same time, the effects of the temperature and load on the anti-friction and anti-wear properties were studied. The morpho-logies and the elemental compositions of the worn surfaces were analyzed using scanning electron microscope(SEM) and X-ray energy spectroscopy(EDS). The results showed that the value of extreme-pressure increased significantly, and the antifriction and anti-wear properties of the LP improved with the addition of HEtHex-(TFS). The optimum value of HEtHex(TFS) as additive in the LP was 0.75%(mass fraction). The best abilities for the anti-friction and anti-wear property of 0.75% HEtHex(TFS) in the LP were found at 25 ℃, 294 and 196 N, respectively. The results of the elemental analysis showed that a protective boundary film was formed on the steel ball surface and it caused that the anti-friction and anti-wear properties was improved. |
