摘　　要：描述了齿轮齿面电蚀失效的微观形貌特征条形花样和云形花样。齿轮失效是复合放电电蚀和摩擦磨损共同作用的结果 ;复合放电电蚀分为非接触放电电蚀和接触放电电蚀 ;建立了单通道非接触放电电蚀模型、接触放电电蚀模型和复合放电电蚀模型 ;阐述了电蚀的原因、机理。The bar and the cloud microcosmic appearance character of the electric erosion is described in this paper.The failure of the gear is the action of the electric erosion of discharge compounded and the friction wear together.The electric erosion of the discharge compounded is divided in two kinds of electric erosion of the discharge contactedand is divided in two kinds of electric erosion of the discharge contacted and the discharge not contacted.The electric erosion model of the single channel discharge not contacted,the electric erosion model of the discharge contacted and the electric erosion model of the discharge compounded are set up.The causation and the mechanism of the electrcic erosion are set forth in this paper.
