Ai-zn-in-mg-ti -(Ce,Mn,Si) sacrificial anode material

In the aluminum alloy sacrificial anode material, the AI-Zn-In system is widely used In the cathodic protection of seawater medium, ships, ocean engineering, etc., because of the high current efficiency (> 80%), the corrosion products are easy to fall off. In recent years, ai-Zn-in-Mg-Ti sacrificial anodes have been gradually applied. The current efficiency of ai-Zn-in-Mg-Ti sacrificial anodes has been improved by adding appropriate alloying elements of magnesium and titanium on the basis of Ai-Zn-In system.

It is an effective way to improve the properties of the alloy by refining the grain to improve the microstructure and reduce the casting defects and the adverse effects of impurity elements.

On the basis of Ai-Zn-in-Mg-Ti anode alloy, adding trace Si/Ce and Mn to improve the microstructure and electrochemical properties of the aluminum alloy anode material by microalloying, so as to prepare high performance aluminum alloy sacrificial anode material.
