摘要：
The influence of aluminium content on the corrosion behaviour of superplastic Zinc-Aluminium alloys immersed in simulated acid rain was investigated. ZA4, ZA8, ZA12, and ZA16 alloys were used for the test. The Al-rich phase was prone to preferential attack when the superplastic Zn-Al alloy was immersed for 5 d. However, with increasing ratios of the Al phase, the corrosion rates of the four samples decreased in the order ZA4 > ZA8 > ZA12 > ZA16. The corrosion rate of the alloy decreased with increasing Al content, which may be related to the distribution of the Al-rich phase. Corrosion kinetic parameters were also calculated.
