摘要/Abstract

摘要： 采用X射线衍射仪、扫描电镜、能谱测试仪、电化学测试仪和电池测试仪等检测技术,分析了轧制退火态AT61(Mg-6%Al-1%Sn)和AP65(Mg-6%Al-5%Pb)镁合金阳极的成分,研究了质量分数分别为3.5%和7.0%NaCl电解液对这两种镁合金阳极电化学性能的影响。结果表明:经430 ℃×16 h均匀化热处理后,轧制退火态AT61和AP65镁合金中Mg₁₇Al₁₂相扩散于基体中;相对3.5%NaCl电解液,两种镁合金阳极在7.0%NaCl电解液中放电性能得到很大提升,同时镁合金-空气电池的放电稳定性得到增强。

Abstract: The composition of the rolled then annealed AT61 (Mg-6%Al-1%Sn) and AP65 (Mg-6%Al-5%Pb) magnesium alloy anodes were analyzed, the effects of 3.5wt% and 7.0wt% NaCl electrolytes on the electrochemical properties of two magnesium alloys were studied by using X-ray diffraction, scanning electron microscopy, energy spectrum analyzer, electrochemical measurement and battery tester. The results show that the Mg ₁₇ Al ₁₂ phase diffuses into the matrix of AT61 and AP65 magnesium alloys after homogenization heat-treatment at 430 ℃ for 16 h; compared with 3.5wt% NaCl electrolyte, the discharge performance of magnesium alloy anodes have been improved in 7.0wt% NaCl electrolyte while magnesium alloy-air batteries have enhanced discharge stability.

Key words: AT61 magnesium alloy, AP65 magnesium alloy, electrochemical property, air battery
