摘要: Abstract Seven kinds of corrosion tests were carried out on thirteen nickel-based alloys in subcritical and supercritical water containing 0.01 mol/kg sulfuric acid (H2SO4) 800 ppm oxygen (O2) using a Ni-44Cr-1Mo autoclave. The obtained rates significantly lower than the previous experiments performed under same conditions titanium A compact oxide scale was found specimens tested chromium-rich layer would originate from autoclave material provide protective function against corrosion. retardation phenomenon has been explained by dependencies chromia (Cr2O3) solubility phase state temperature.
