摘要:本发明提供一种铝或其合金的表面处理方法,其中在往硫酸浴、草酸浴或其混合浴中作为金属硝酸盐的加入了硝酸银和/或硝酸铜的或者作为金属硫酸盐地加入了硫酸银和/或硫酸铜的电解液中,施加交直重叠电流、流动负波的PR电流或流动负波的脉冲波的电流地电解由铝或其合金形成的母材,由此一来,当在母材表面上形成阳极氧化膜的同时,使所添加的硝酸盐或硫酸盐的金属析出在该阳极氧化膜上。
主权项:1.一种铝或其合金的表面处理方法,其特征在于,在往硫酸浴、草酸浴或其混合浴中作为金属硝酸盐加入了硝酸银和硝酸铜的任一种或两种或者作为金属硫酸盐加入了硫酸银和硫酸铜的任一种或两种的电解液中,施加交直重叠电流、流动负波的PR或流动负波的脉冲波的电流,电解处理由铝或其合金形成的母材,从而,在母材表面上形成阳极氧化膜的同时,使所添加的硝酸盐或硫酸盐的金属析出在该阳极氧化膜上。
