摘要
提出了一种适用于铝合金的化学氧化新工艺,配方采用以铬酸盐为主要成分的水溶液.此方法工艺简单,成本低,生成无色或浅黄色的氧化膜,耐蚀性能好,且提高了零件表面对有机涂层的附着性,还可作为涂漆底层.
A ncw process of chemical oxidation for aluminum alloys is discussed. A dilute basic chromate solution was used as the primary solution for surfacc treatment on Al alloys. After a colorless or light yellow oxidation film was created by the process, either the corrosion resistance of the parts or the adhesion to the organic painting was remarkably improved. The process is also easy in technology and low cost for apllication.
