高压电器用铝合金零件表面金属异物去除工艺

Processes for removing foreign metallic matters from surfaces of aluminum alloy parts applied to high-voltage electrical apparatus

分别采用超时碱洗法、硬质阳极氧化法和电化学整平法处理机加成型和旋压成型的1060铝合金表面,对比了3种方法对金属异物的去除效果,总结了各自的优缺点和适用场合。

The machined and spun 1060 aluminum alloys were treated by excessive alkaline washing,hard anodization,and electrochemical leveling,respectively.The removal efficiency of metallic residues by the three methods was compared,and their advantages/disadvantages and application scopes were summarized.
