Abstract
In addition to single nickel crystals also nickel samples produced
by dc and pr (pulse-reversal) plating were examined. As previously
reported the true rate of dissolution of nickel in solutions
containing oxygen was found to be as much as three times the
electrochemical rate at the corrosion potential. When passivation
was approached (spontaneously or by anodic polarization) the true
rate of dissolution approached the rate of anodic reaction. During
cathodic polarization there was still a significant rate of
dissolution. The true rate of dissolution was determined by CMT
measurements (Corrosion Measurements by Titration).
Electrochemical measurements (EC) indicating the rate of
electrochemical reactions were made simultaneously.
