摘　　要：针对涡流器阵列叶片电解加工过程中未加工区域杂散腐蚀问题,通过研究阴极外轮廓几何形状对杂散腐蚀的影响,采用仿真分析和试验验证优化阴极外轮廓的几何参数,从而实现对未加工区域杂散腐蚀的有效控制,并避免表面凸起的产生。结果表明,在阴极外轮廓参数为斜角角度30°、半径14 mm时,杂散腐蚀深度较无斜角时减少了90%,且表面几乎无凸起,与仿真结果一致,这为解决涡流器叶片电解加工中未加工区域的损伤问题提供应用价值。In response to the problem of stray corrosion in the raw area during the electrochemical machining of vortex array blades,the influence of the geometric shape of the cathode outer contour on stray corrosion was studied.Simulation analysis and experimental verification were used to optimize the geometric parameters of the cathode outer contour,so as to control stray corrosion in the raw area and avoid the generation of surface bulges.The result showed that when the cathode outer contour parameters were inclined at an angle of 30°and a radius of 14 mm,the depth of stray corrosion was reduced by 90%compared with no inclined angle,and the surface had almost no protrusions,which was consistent with the simulation result.This provides practical value for solving the damage problem of unprocessed areas in the electrochemical machining of vortex generator blades.
