摘要
为改善电化学光整加工整平效果,根据电化学光整加工前后表面微观轮廓的变化,在提出的圆锥体和半球体表面微观几何形貌的基础上,建立了极间电流场的数学模型,并分析了电化学光整加工过程中电流场分布特性的变化。研究结果表明,尖峰状表面微观几何轮廓有利于强化电化学的选择性溶解,有利于提高整平效果,验证了电化学光整加工过程中,机械作用具有使表面微观几何轮廓尖峰化的作用。
To improve the effect of electrochemical finishing leveling, according to change of surface profile before and after electrochemical finishing, based on micro-meometry contour of the surface of cone and hemisphere, this study established the mathematical model of current field, and analyzed the process of electrochemical finishing characteristics of current changes in field distribution. The result shows that micro - geometry of spike - like contour surface is conducive to strengthening selective electrochemical dissolution, helping improve the leveling effect. In the electrochemical mechanical finishing process, surface micro-geometry has been validated because of mechanical action.
