摘　　要：为南海某海区海底输油管线的保护寻找在海泥中性能较优的铝合金牺牲阳极。通过对AZIS和AZIG在常温及热海泥中恒电流试验和阳极溶解形态分析 ,找到较为满意的阳极材料 ,供海上油气田工程设计参考。Several aluminum sacrificial anodes were tested by all kinds of measurement including the galvanostatic tests in the seabed mud under normal and moderate temperature, examination of macro\| and micro\| morphology of dissolving anode surface. A sacrificial anode material having excellent performance was found and fit to prevent oil\|carrying pipeline corrosion by cathodic protection in seabed mud.
