Abstract

To improve the efficiency of magnesium sacrificial anodes used in corrosion protection, the effect of microstructure was investigated. Efficiency was improved by controlling the amount of second-phase particles at grain boundaries, by producing a uniform distribution of impurities in the matrix, and by ensuring a micrometer-order cell size via cooling rate and heat treatment. After evaluation with the efficiency test, it was found that the efficiency values were quite good as compared with commercially available magnesium sacrificial anodes.
