摘要:
采用熔炼法制备了一系列Mg-Al-Pb-Ga--0.9Y海水电池用镁合金阳极材料。利用金相显微镜(OM)、扫描电镜(SEM)、X射线衍射(XRD)和电化学测试等方法研究了Pb、Ga元素对合金组织和电化学性能的影响。结果表明, 合金的放电电压随Pb含量增加而提高。 Pb含量为5wt%且Ga的添加量为1wt%时, 对放电电压的提升效果达到最优,合金在20mA/cm2和100mA/cm2电流密度下放电均有较大的放电电压。成分为Mg-3Al-5Pb-1Ga-0.9Y的镁阳极具有更优异的综合性能, 其放电电位最负, 在电流密度为20mA/cm2和100mA/cm2下的工作电位分别为-1.723V和-1.680V;合金的自腐蚀速率较低, 腐蚀电流密度为5.1164×10-5 A/cm 2。
