氟化镧对固体润滑粘结膜摩擦学性能的影响及其作用机理之研究

Study of the Influence of Lanthanum Fluoride on the Tribological Properties of Bonded Solid Film Lubricants and its Mechanism of Function

对于氟化镧（ＬａＦ３）对酚醛－环氧粘结的二硫化钠（ＭｏＳ２）干膜性能的影响进行了考察，并着重应用表面分析工具对其作用机理进行了研究。结果表明，与不含ＬａＦ３的干膜相比，当含有适量ＬａＦ３时，干膜的耐磨寿命明显增加。在摩擦过程中，ＬａＦ３减少了干腔中ＭｏＳ２的氧化趋势。

The influence of lanthanum fluoride(LaF3) on the characteristics of phenolepoxy -bonded MoS2 dry films was investigated. The functional mechanism was specifically studied using several analytical means. The results showed that the wear life of dry films containing a certain amount of LaF3 was considerably increased over that of the films without LaF3 However the effect of LaF3 on the friction coefficient of the dry films was shown to be negligible. It was found that the addition of LaF3 is effective in reducing the oxidation tendency of MoS2 in the films during the friction process. The reason for this is investigated by the authors.
