The Current Research State and Orientation of Development on Ahuninium Alloy Sacrificial Anode

文章综述了铝合金牺牲阳极材料的研究现状．和目前常用的三类铝合金牺牲阳极材料的基本化学成分和性能特点，分析了合金元素和杂质元素的影响，并对铝合金牺牲阳极的一些新发展作了介绍．

In this paper, the current research state on aluminium alloy sacrificial anodes is reviewed. The general features and chemical composition of three kinds of commonly used aluminium alloy sacrificial anodes materials are described respectively. The effect of alloying elements and influ-ence of impurities as well as some new developments of sacrificial anodes are also introduced.
