采用低温离子硫化这一新的等离子体源方法在aisi1045钢表面制备了FeS薄膜。在板上球试验机上对膜的抗摩擦性能进行了测试，结果表明膜具有良好的抗摩擦性能。采用原子力显微镜（AFM）和扫描电镜（SEM）对FeS薄膜表面形貌和磨损痕进行了分析。利用SAM探测地表元素随深度的分布。建立了FeS膜的物理减摩模型，并通过SAM分析进行了验证。结果表明，在摩擦过程中，FeS膜形成了分解与重组的动态平衡。因此，该薄膜具有较长的固体润滑时间。
A new plasma source method, low temperature ion sulfuration, was utilized to prepare the FeS film on the AISI 1045 steel surface. The anti-friction property was tested on the ball-on-plate tester and the results showed the film holds the excellent performance. AFM and SEM were adopted to analyze the morphologies of surfaces and wear scars of the FeS film. SAM was employed to detect the surface element distribution with depth. The physical friction–reduction model of the FeS film was formed and was verified by SAM analysis. Results showed that in the course of friction, FeS film formed a dynamic balance between decomposing and recomposing. Therefore the thin FeS film could last a long solid lubrication time.
