Observation was carried out of the structure of sulphuric,oxalic or phosphoric film on Al after treatment of reanodizing and electrolytic depositing lubricant in (NH_4)_2MoS_4 solution,as well as of the deposited products by means of EMPA,TEM and energy spectro-scopic analysis.The deposited products are mixture of compounds of S and Mo rather than single MoS_2 and most of them dcposited near the surface layer of the film.Some regular long pores without barrier layer occurred in the film,but the regular fine channels without relation to the structural element parameters of original anodized film were found in the thickened barrier layer of phosphoric film.Sulphur may be remained as Mo sulphide in the film during heating under Ar protective environment.

为研究环氧树脂粘接固体润滑涂层的摩擦磨损性能及机理,采用端面摩擦磨损试验机在干摩擦变载荷条件下进行了该涂层的摩擦磨损性能试验与分析,结果表明,试验初期涂层表面的环氧树脂与钢对偶件直接接触,减摩润滑效果不佳;随着载荷的增加与时间的延长,涂层表面逐渐形成固体润滑保护薄膜以及在对偶件表面形成转移润滑层,涂层进入稳定摩擦磨损阶段并显示出优异的减摩润滑性能;当载荷超过涂层承载能力时,涂层表面磨损加剧,直至涂层剥落、失效。
