The effect of the elemental content of aluminum on electric conductivity and corrosion resistance of anodes

In this paper, the effect of the elemental content of aluminum in cermets on the electric conductivity and corrosion resistance of anodes was analyzed. The experimental results demonstrate that both corrosion resistance and electrical conductivity decrease when the elemental content of aluminum increases in the dense layer on the anodes’ surface. This can be attributed to the formation of FeAl₂O₄ and NiAl₂O₄ as production of FeAl₂O₄ and NiAl₂O₄ occur on the surface of the anodes during electrolysis.
