The electrochemical performance and discharge behavior of Al–0.8Sn–0.05Ga–0.9Mg–1.0Zn (wt%) alloys in as‐cast, homogenized, and annealed states were investigated through electrochemical means, corrosion rate test, and discharge test in a 3.5 wt% NaCl solution. Results suggest that the discharge performance of this alloy is enhanced by rolling and subsequent annealing treatment. This is attributed to the fact that the microstructure of the alloy is greatly improved through rolling and subsequent annealing treatment. The 400°C‐annealed alloy exhibits the most excellent discharge activity than alloys in other states, which is due to more regions being activated by a finer and more uniform Sn‐rich phase. Furthermore, the anode efficiency of the 400°C‐annealed alloy is higher than that of as‐cast and homogeneous alloys due to the more uniform distribution of Sn in the aluminum matrix.

微观结构对作为海水活化电池阳极的Al–0.8Sn–0.05Ga–0.9Mg–1.0Zn（wt％）合金放电性能的影响

通过电化学手段，腐蚀速率测试和放电测试，研究了Al–0.8Sn–0.05Ga–0.9Mg–1.0Zn（wt％）合金在铸态，均质化和退火状态下的电化学性能和放电行为。 3.5重量％的NaCl溶液。结果表明，通过轧制和随后的退火处理可提高该合金的放电性能。这归因于通过轧制和随后的退火处理极大地改善了合金的微观结构的事实。与其他状态的合金相比，经过400°C退火的合金具有最优异的放电活性，这是由于更多的区域被更细，更均匀的富锡相活化了。此外，
