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。
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. 5 wt% and 7. 0 wt% 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 Mg17Al12 phase diffuses into the matrix of AT61 and AP65 magnesium alloys after homogenization heat-treatment at 430 ℃ for 16 h;compared with 3. 5 wt% NaCl electrolyte,the discharge performance of magnesium alloy anodes have been improved in 7. 0 wt% NaCl electrolyte while magnesium alloy-air batteries have enhanced discharge stability.
