摘　　要：采用由经过专门筛选的混合有机酸及添加剂组成的电解液,对铝合金进行了常温(0～40℃)硬质阳极氧化,经实际生产验证,其质量可靠、实用性强.同时,在不采用特殊波形电源的条件下,在高硅及含硅22%～24%的超高硅铸铝合金表面上获得了均匀、致密、高硬度的阳极氧化膜。Hard anodizing of aluminium alloy at 0～40℃ was carried out successfully in a electrolyte containing several specially choosed organic acids and additives.It has been proved that this process is practically applicable and reli- able in the production line in factory.The uniform,compact and high-silicon and super high-silicon aluminium al- loys,(22%～24%wt silicon)without special power.
