摘　　要：通过对传统着色工艺的改进 ,摸索出了一种以硫酸镍为着色液中的主体盐 ,添加适量的氯化铜及添加剂 ,在适当的工艺规范下 ,可以得到赭红色膜的着色工艺。研究了着色液中 Cu Cl2 含量、着色时间等因素对铸造铝合金 ZL 1 0 5表面着赭红色效果的影响 ,并考察了膜的耐腐蚀性能。Through the improvement of traditional coloring technologies, a coloring technology for casting aluminum alloy to obtain a reddish brown color film was developed. The technology uses a coloring solution containing nickel sulfate as the main salt, a proper amount of copper chloride and additive. Different factors affecting coloring effect and corrosion resistance of the film, such as coloring time. CuCl 2 concentration etc., were studied. Technological conditions suitable for casting aluminum alloy ZL105 was proposed.
