超塑性锌铝合金的腐蚀行为
Corrosion Behavior of Superplastic Zn-Al Alloys
摘 要
研究了超塑性锌铝合金在氯化钠和硫酸钠溶液中的腐蚀速率。在铝含量为2%～18%的范围内, 合金中的铝能有效提高其抗腐蚀性能。合金的耐蚀性完全由其化学成分决定, 晶粒大小对其几乎没有影响。在硫酸钠溶液中, 富铝相被优先腐蚀; 在氯化钠溶液中, 富锌相被优先腐蚀。

Abstract
The corrosion rates of superplastic Zn-Al alloys in HCl and Na2SO4 solutions were studied. When Al content is in the range of 2%~18%, adding Al in the alloy can increase its corrosion resistance. The corrosion resistance of the alloy is determined by the chemical composition, the influence of the grain size is little. Al-rich phase is corroded preferentially in Na2SO4 solution, and Zn-rich phase is corroded preferentially in NaCl solution.
