|
摘要
以异辛基乙二胺-CF_3SO_3[HEt Hex(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HEt Hex(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HEt Hex(TFS)添加剂可明显增大LP的最大无卡咬负荷(P_B)值,改善LP的减摩抗磨性能. HEt Hex(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HEt Hex(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.
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 morphologies 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.
