用红外显微镜（ＦＴＩＲ ｍ ｉｃｒｏｓｃｏｐｅ）和Ｘ射线光电子能谱（ＸＰＳ）研究了静态下硫化异丁烯（ＳＯ）、亚磷酸二正丁酯（ＤＢＰ）、二烷基二硫代磷酸锌（ＺＤＤＰ）及十二酸（ＬＡ）以质量分数２％ 的比例添加到液体石蜡中与铝合金所形成的油浸反应膜的化学组成及结构．结果表明：ＤＢＰ易与铝合金发生化学反应并形成主要由亚磷酸铝组成的表面膜；ＺＤＤＰ在１８０ ℃下与铝合金反应形成主要含磷酸铝的表面膜；ＳＯ及ＬＡ 与铝合金不发生化学作用，但在９０ ℃或１８０ ℃下发生降解并在铝合金表面发生吸附．结合摩擦磨损试验结果与油浸反应试验结果发现，油浸试验后铝合金表面膜的摩擦磨损性能与添加剂的化学活性密切相关；ＤＢＰ最易与铝合金发生反应，相应表面膜摩擦系数最低，耐磨寿命最长；ＺＤＤＰ在１８０ ℃下与铝合金发生反应，其表面膜的摩擦系数较低，耐磨寿命较长；ＬＡ 及ＳＯ 不与铝合金发生作用，相应的表面膜的减摩抗磨性能不佳．
The static state of sulfided isobutylene (SO), di-n-butyl phosphite (DBP), zinc dialkyldithiophosphate (ZDDP) and ten The chemical composition and structure of the oil-immersed reactive film formed by adding diacid (LA) in a ratio of 2% by mass to liquid paraffin and aluminum alloy are shown. The results show that DBP easily reacts with aluminum alloy and forms a surface film mainly composed of aluminum phosphite. ZDDP reacts with aluminum alloy at 180 ℃ to form a surface film containing mainly aluminum phosphate. SO and LA do not chemically react with aluminum alloy But degraded at 90 ° C or 180 ° C and adsorption occurred on the surface of the aluminum alloy. Combining friction and wear test results and oil immersion test results, it is found that the friction and wear properties of the aluminum alloy surface film after oil immersion test are closely related to the chemical activity of the additive. DBP is most likely to react with the aluminum alloy with the lowest surface friction coefficient, ZDDP reacts with aluminum alloy at 180 ℃, the friction coefficient of the surface film is lower and the wear life is longer; LA and SO do not interact with the aluminum alloy, and the corresponding anti-friction and wear-resistance of the surface film Poor performance.
