摘　　要：采用复合电沉积技术在Q235钢基体表面制备了Cu-MoS2复合镀层,对镀层的截面形貌和组织结构进行了观察,并考察了镀液中MoS2颗粒含量对复合镀层耐磨减摩性能和耐蚀性的影响。结果表明,MoS2颗粒均匀分布在Cu基金属中,镀层与基体结合良好,无空隙和裂纹等缺陷,镀态下镀层为晶态结构;当镀液中MoS2颗粒含量为25g/L时,镀层的减磨耐磨性达到最佳;镀层的耐蚀性,随着MoS2颗粒含量的增加逐渐升高并趋于稳定。Cu-MoS2 composite coatings with different content of MoS2 were deposited on Q235 steel substrate by composite electro-deposition technique. The morphology and phase of the coatings were studied. The influences of concentration of MoS2 particle in bath on the wear resistance and corrosion resistance of the coatings were investigated. The results show that the presence of MoS2 particles homogeneously disperse in the entire Cu film matrix. The coating shows a good adhesion to the substrate, and the structure of Cu-MoS2 composite coating as deposited is crystalline. The wear resistance of the composite coating reaches optimum level when the MoS2 in plating bath is about 25 g/L. The corrosion resistance of the composite coating increases with increasing the concentration of MoS2 in plating bath and then tends to be steady.
