摘要：

The loss of nickel under cathodic polarization in molten NaNO3 increased with an increase in the quantity of electricity for the cathodic reaction. The formation of NiO was observed on the surface of the nickel after cathodic polarization. A large amount of powdered corrosion product consisting of NiO was detected in the NaNO3 Salt after cathodic polarization. The cathodic polarization reaction and the products by the cathodic polarization reaction were examined in order to determine a mechanism for the cathodic corrosion of nickel in molten NaNO3. On the basis of the results it was proposed that the corrosion of nickel under cathodic polarization in molten NaNO3 occurred by a chemical reaction of nickel with NO2 and O2- which appeared to be cathodic products.
