Influence of Rare Earth on Corrosion Resistance of Aluminum Rods for Electrical Purpose

For pushing the anticorrosion research on the electrical aluminum, the influence of the rare earth element on the corrosion resistance of the aluminum rods for electrical purpose in the different density acid, the alkali, the salt solution was investigated. The results show that the anti-corrosive performance of the aluminum rod containing the rare earth element for electrical purpose is distinctly improved, and the anti-corrosive performance is related to corrosive medium and the components of the aluminum rods for electrical purpose.
