## A&r&-Electrochemical impedance data for single crystal Ni( 111) in phosphate buffer solutions of pH 9, 10, and 11 and at potentials spanning the passive range (0.1-0.5 V/see) are interpreted in terms of a point defect model for the passive film in which the kinetics of generation and annihilati
The formation and reduction of the passive film on iron was investigated in a phosphate-borate buffer solution. The passive film produced in the present solution was approximately 12% thicker than that produced in the borate-boric acid solution (pH 8.4). The formation ofthe passive film obeyed the m
