The electrochemical behavior of the nickel specimen heated in boiling NaOH solutions under atmospheric pressure was investigated. Nickel was attacked by caustic soda in the form of intergranular corrosion as well as uneven general corrosion when the corrosion potential was located at the active region. Corrosion was accelerated by chlorate in the solution.
