摘要

为提高铝合金的表面硬度并降低其在摩擦磨损过程中的摩擦系数，在电解液中添加二硫化钼纳米粒子，利用微弧氧化技术在ZL109铝合金表面制备出含有二硫化钼的复合陶瓷层，且其表现出良好的摩擦学性能.添加二硫化钼纳米粒子后，陶瓷层的表面粗糙度降低，但是硬度未发生明显改变.在摩擦磨损试验中，复合陶瓷层的摩擦系数相对普通陶瓷层有所降低.在二硫化钼纳米粒子质量浓度为5g/L时，陶瓷层的摩擦系数最低，相对普通陶瓷层下降47%.

Abstract

In order to improve the surface hardness of aluminum alloy and reduce its friction coefficient in the friction process, by the addition of MoS₂ nanoparticles into the electrolyte, MoS₂-containing ceramic layer was prepared on the surface of ZL109 aluminum alloy through the technology of Micro-arc oxidation, and the composite ceramic layer exhibited good tribological properties. After adding MoS₂ nanoparticles, the surface roughness of the ceramic layer decreases, but the hardness does not change significantly. In the friction and wear test, the friction coefficient of the composite ceramic layer is lower than that of the common ceramic layer. When the mass concentration of MoS₂ nanoparticles is 5 g/L, the friction coefficient of ceramic layer is lowest, and it is lower than that of common ceramic layer by 47%.

Key words： nano molybdenum disulfide; composite ceramic layer; micro-arc oxidation; friction coefficient
