基于局部电场控制微弧氧化设备的研制与应用

摘要

Plenty of technical problems of traditional micro-arc oxidation equipment are difficult to deal with during application. A new method of local electric-field control was put forward for micro-arc oxidation treatment of large part, which using shielding anode and on the basis of local discharging and putting the integrity into pieces. A local electric-field control micro-arc oxidation equipment with moving cathode was designed and developed, which realized the micro-arc oxidation treatment of large work surface. Moreover, this equipment can be used to repair engineering equipment by treating the corrosion damage of key position with its simple and convenient operation.%针对微弧氧化技术推广应用过程中传统微弧氧化处理设备难以解决的技术难题,在局部放电、化整为零的思路基础上,通过屏蔽阳极(待处理工件),创新了大面积微弧氧化处理的局部电场控制新方法,设计研制了一种带有移动阴极的局部电场控制微弧氧化设备.实现了对大尺寸工件表面微孤氧化处理以及装备腐蚀损伤关键部位的原位绿色维修,操作简单,使用方便快捷.
