摘　　要：对Al-0.4Mg-0.015Ga-0.1Sn阳极合金以460 ℃、500 ℃、540 ℃、580 ℃、620 ℃固溶温度保温2 h后水淬的方式进行固溶处理试验,研究不同固溶温度对Al-0.4Mg-0.015Ga-0.1Sn阳极合金的组织与电化学性能影响。研究结果表明:当固溶温度为580℃时,该阳极合金具有较高的耐蚀性以及最高的放电性能,且合金的综合性能最优;在100 mA/cm^(2)的恒电流密度放电条件下,稳定输出电压达到1.13V,阳极利用率和燃料利用率分别达到88%和37%。The Al-0.4 Mg-0.015 Ga-0.1 Sn anode alloy was heat-treated at 460 ℃, 500 ℃, 540 ℃, 580 ℃, 620 ℃ for 2 h and water quenched afterwards so that the effects of different solid solution temperatures on the structure and electrochemical properties of Al-0.4 Mg-0.015 Ga-0.1 Sn anode alloy were studied. Studies have shown that when the solid solution temperature is 580 ℃, the anode alloy has higher corrosion resistance property and the best activation performance, and the comprehensive performances of the anode alloy are the best. Under the constant current discharge condition of 100 mA·cm^(-2), the stable output voltage reaches 1.13 V, and the anode utilization rate and fuel utilization rate reaches 88% and 37%, respectively.
