The rates of growth of anodic oxide films at PI m acid and alkahna solutions and Ni III alkaline solutibns are compared. In acid solutions, the rates are pH independent. In alkaline solutions. they are affected by pH. The exchange current densities, i,, in alkaline solutions increase one decade as p
