摘　　要：介绍了海底管道在海洋环境下腐蚀机理,比较了锌基、铝基、镁基牺牲阳极用在海底管道阴极保护的优缺点,分析了铝阳极更适合海底管道牺牲阳极保护的原因。The corrosion mechanism of submarine pipeline in the Marine environment is introduced in this paper. And the advan- tages and disadvantages of the zinc, aluminum, magnesium-based sacrificial anode used in submarine pipeline cathodic protection are compared in the work. The reason why aluminum anode is more suitable for sacrificial anode in the submarine pipeline protection is al- so analyzed in the article.

关 键 词：铝基牺牲阳极 海底管道 阴极保护
