摘要： A process for reducing the corrosion of nickel metal in an alkali metal hydroxide evaporator equipment which comprises the step of impressing a total protection potential directly upon the nickel metal material in alkali metal hydroxide evaporator that is in contact with an aqueous alkali metal hydroxide solution during evaporation of that solution; said total potential being sufficient to reduce the amount of corrosion of the nickel metal to an oxide that may dissolve in the alkali metal hydroxide solution.
