为了获得铅含量更低的 Mg?Al?Pb 合金阳极材料，采用浸泡实验及电化学测试技术研究了Mg?9%Al?2.5%Pb(质量分数)合金的腐蚀及放电行为，并与Mg?6%Al?5%Pb合金进行比较。研究表明：与Mg?6%Al?5%Pb相比，更高的Al含量使得Mg?9%Al?2.5%Pb合金具有更低的自腐蚀速率及更高的阳极利用率；由于Pb含量降低，其放电活性有所减弱但仍能满足阳极材料的要求。因此，Mg?9%Al?2.5%Pb合金有望作为海水激活电池阳极的备选材料，并且其具有更低的Pb含量。
To obtain a new kind of Mg?Al?Pb alloy anode material with low content of Pb, the corrosion and discharge behavior of Mg?9%Al?2.5%Pb (hereafter in mass fraction) alloy were investigated by immersion tests and electrochemical techniques, and compared with those of Mg?6%Al?5%Pb alloy. The results indicate that Mg?9%Al?2.5%Pb alloy exhibits a lower self-corrosion rate and higher utilization efficiency in contrast with Mg?6%Al?5%Pb alloy because of the higher content of Al. As the result of the decrease of Pb content, the discharge activity of Mg?9%Al?2.5%Pb alloy is relatively weaker but still meets the requirement of anode. These results reveal that Mg?9%Al?2.5%Pb alloy with a low content of Pb can serve as a good candidate for the anode material used in seawater activated battery.
