目的 改善微弧氧化陶瓷膜层的摩擦学性能。方法 采用微弧氧化技术和抛磨技术相结合的方法在ZL109合金表面制备微弧氧化陶瓷和固体润滑剂复合膜层。利用粗糙度仪检测试样表面粗糙度，并在球盘往复式摩擦磨损试验机下检测复合膜层的摩擦学性能。使用扫描电镜（SEM）分析试验前后试样表面微观形貌及对磨钢球磨斑形貌，并利用能谱分析仪（EDS）对试样膜层化学成分进行分析。结果 在抛磨纳米WS2粉体过程中，WS2可有效填充陶瓷膜疏松层上的放电微孔以及经抛光的陶瓷膜层表面残留的微孔缺陷，并极大地降低试样表面粗糙度，进而影响实验前期的摩擦系数及抗粘着时间。试样MAO-W比试样MAO粗糙度降低约34.2%，摩擦系数降低79.2%，抗粘着时间增加900%。试样P-MAO-W比试样P-MAO粗糙度降低约41.3%，摩擦系数降低93.6%，抗粘着时间增加233%。另外，制备的试样可以有效减轻对磨钢球的磨损，并且试样的磨痕宽度及对磨钢球的磨斑直径变化规律与摩擦过程中的摩擦系数变化及粗糙度变化趋势相吻合。结论 在铝合金微弧氧化陶瓷膜层表面抛磨纳米WS2自润滑粉体可有效降低摩擦，延长抗粘着时间并减轻对磨件的磨损。

The work aims to improve the tribological properties of micro-arc oxidation (MAO) ceramic coatings. The MAO ceramic and solid lubricant composite layer was prepared on the surface of ZL109 alloy by micro-arc oxidation and polishing technology. The roughness of the samples was measured by roughness tester. The tribological properties of the composite layer were evaluated by ball-disk friction and wear tester. The surface morphology of the samples before and after the test and the morphology of the coupling steel balls were analyzed by scanning electron microscopy (SEM). The chemical composition of the layer was analyzed by energy dispersive spectrometer (EDS). The discharge micro-pores on the porous MAO ceramic layer and the micro-dimple defects remaining on the surface of the polished ceramic layer could be effectively filled by WS2 during the polishing of WS2 nano-powders. The surface roughness of the sample was greatly reduced through this method. The friction co-efficient in the early stage of the experiment and anti-adhesion time were affected. Compared with sample MAO, the roughness of sample MAO-W was about 34.2% lower, the friction coefficient was reduced by 79.2%, and the anti-adhesion time was increased by 900%. Compared with sample P-MAO, the roughness of sample P-MAO-W was reduced by about 41.3%, friction coefficient was reduced by 93.6%, and anti-adhesion time was increased by 233%. Beside this, the wear on the coupling steel ball could be effectively reduced by prepared samples. The variation of the width of wear scar of the samples and the diameter of the wear spot of coupling steel ball coincided with the change trends of the friction coefficient and the roughness of the samples during the friction process. Polishing WS2 self-lubricating nano-powders on aluminum MAO ceramic coatings of Al alloy can effectively reduce friction, improve wear life and mitigate wear on abrasive parts.
