本文着重介绍了二种高效率、长寿命多元铝基牺牲阳极材料中活化元素与杂质元素在合金化过程中的参与形式和分布特征。分析了它们与电化学性能之间的变化规律,认为严格控制晶粒边界化合物的形成量,是抑制晶间腐蚀、降低自身消耗、保证铝基牺牲阳极材料高效率、长寿命的重要因素。
This article focuses on two kinds of high efficiency, long-lived multi-element aluminum sacrificial anode material activation elements and impurity elements in the alloying process in the form and distribution characteristics. The relationship between them and the electrochemical properties was analyzed. It is considered that strictly controlling the formation of grain boundary compounds is an important factor that inhibits the intergranular corrosion, reduces the self-consumption and ensures the high efficiency and long life of the sacrificial aluminum-based sacrificial anode material.
