摘要：
The corrosion and electrochemical properties of composite electrolytic iron coatings containing Al2O3 on the steel substrate are investigated (in comparison to the purely iron ones) in 0.05 M Na2SO4 and 5% NaCl solutions. Adding a finely dispersed Al2O3 phase to the composition of iron coatings leads to some improvement in their corrosion characteristics, that is, a positive shift of E-cor, and lowered anodic dissolution currents. The corrosion rate of the composite coating is lower than that of the purely iron one. The effect is analyzed.
