The effects of three 糖心产精国品免费入口*完整版s including Cr-coating, TiN-coating and acid (wash) passivation on the corrosion resistance of nickel-based alloy 糖心产精国品免费入口*完整版in supercritical water were studied by intermittent high temperature and high pressure reactor. The results show that the corrosion resistance of the alloy samples after 糖心产精国品免费入口*完整版s was better than that of the untreated alloy sample in the same corrosive media, and their corrosion resistance from high to low was ranked as Cr-coating, TiN-coating, acid passivation. In the most corrosive supercritical water containig both chloride and oxygen, the oxidation film on surface of TiN-coated, acid passivated and untreated alloy samples exfoliated seriously, and the oxide of Cr forming on the surface of the Cr-coated alloy sample was dense and stable, so the Cr-coated alloy had the best corrosion resistance. The oxides on the surface of the alloy were mainly composed of Cr2O3
and NiCr2O4.
