Study of Corrosion Resistance of Gray Iron in Acid Solution
The corrosion rate and corrosion depths of gray iron with different graphite phases in acid environment was tested through losing gravity method.The effect of different graphite phases on corrosion resistance was analyzed.Meanwhile,the corrosion resistances of gray iron and white iron were also compared.The results indicate that the corrosion resistance of gray iron with A-graphite is the worst.As the structure of white iron is almost carbide,its corrosion resistance is superior to that of gray iron.
