静态下分别于２５℃，９０℃及１８０℃下进行硫化异丁烯（ＳＯ）、亚磷酸二正丁酯（ＤＢＰ）、ＳＯ＋ＤＢＰ的混合物（质量比２０∶１）、二烷基二硫代磷酸锌（ＺＤＤＰ）及十二酸（ＬＡ）５种添加剂均以质量分数为２％的比例添加到液体石蜡（ＬＰ）中与铝合金进行油浸试验．用动－静摩擦系数精密测定仪评价了在铝合金表面上所形成的静态反应膜的摩擦磨损行为，并考察了上述添加剂在ＬＰ中对铝合金－钢摩擦副的润滑作用．结果表明：静态反应膜的摩擦磨损行为与添加剂的化学活性密切相关，其中ＤＢＰ最易与铝合金发生反应，故其反应膜具有最低的摩擦系数和最长的耐磨寿命；ＺＤＤＰ在１８０℃下的静态反应膜具有较低的摩擦系数和较长的耐磨寿命；ＳＯ、ＳＯ与ＤＢＰ的混合物及ＬＡ的静态反应膜则不具有减摩抗磨性能，预示这些添加剂在ＬＰ中不与铝合金发生较强的化学作用．含上述添加剂的ＬＰ润滑下的摩擦磨损试验显示，ＤＢＰ与ＺＤＤＰ具有较好的摩擦学性能．这表明添加剂在铝合金表面静态反应膜的摩擦磨损试验结果与其在常规润滑下的具有较好的相关性．
A mixture of isobutylene sulphide (SO), di-n-butyl sulphite (DBP) and SO + DBP in a mass ratio of 20: 1 and zinc dialkyldithiophosphate ZDDP) and lauric acid (LA) were added to liquid paraffin (LP) at a mass fraction of 2% to conduct oil immersion test with aluminum alloy. The tribological behavior of the static reaction film formed on the surface of aluminum alloy was evaluated by the dynamic-static friction coefficient tester, and the lubrication of the additive on the aluminum alloy-steel friction pair was investigated. The results show that the friction and wear behavior of the static reaction membrane is closely related to the chemical activity of the additives. Among them, DBP is most likely to react with the aluminum alloy. Therefore, the reaction membrane has the lowest friction coefficient and the longest wear life. Of the static reaction film has a lower coefficient of friction and longer wear life; SO, SO and DBP mixture and LA static reaction film does not have anti-friction and anti-wear properties, indicating that these additives are not in the LP and aluminum alloy A strong chemical effect occurs. Friction and wear tests of LP lubricated with the above additives show that DBP and ZDDP have good tribological properties. This shows that the additives on the surface of the static reaction film friction and wear test results with its conventional lubrication has a good correlation.
