摘　　要：本文采用Na_(2)WO_(4)+Na_(2)SiO_(3)+Na_(3)PO_(4)电解液,采用恒流模式在TC4合金基体上制备了微弧氧化层,研究了不同添加浓度钛硅碳颗粒(2~8 g/L)对陶瓷层表面形貌、组织结构、摩擦曲线的影响。结果表明:电解液中钛硅碳浓度对氧化陶瓷层表面形貌、物相组成影响较小,同时添加钛硅碳增强了电解液的电导率,改善降低了起弧电压,有利于陶瓷层的厚度增加,同时减小摩擦。实验中,4 g/L时陶瓷层表面质量最好,8 g/L时减磨性最好。In this paper,micro-arc oxidation layers were prepared on TC4 alloy substrates using Na_(2)WO_(4)+Na_(2)SiO_(3)+Na_(3)PO_(4)electrolyte in constant current mode,and the effects of different added concentrations of titania silicon carbon particles(2~8 g/L)on the surface morphology,structure and friction curve of the ceramic layers were investigated.The results show that the concentration of titanium silicon carbon in the electrolyte has less influence on the surface morphology and phase composition of the oxide ceramic layer,while the added input of titanium silicon carbon enhances the conductivity of electrolyte,improves and reduces the arc voltage,which is beneficial for the increased thickness of ceramic layer and the reduction of abrasion.In the experiments,the best surface quality of the ceramic layer was achieved at 4 g/L and the best abrasion reduction at 8 g/L.
