## 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
Passivation of spec-pure Sn was studied in aerated, unstirred solutions of acid sulphate (H2S04/Na2S04) and neutral suphate (Na2S04) using the potentiodynamic technique from an initial cathodic potential (-ve to open circuit potential) in the anodic direction and backwards to the initial potential.
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
Abstrac(-Pure iron specimens anodically oxidized at +600 mV (us see) for one minute were partially reduced with a cathodic current of lOpA/crn" and then reoxidized at the same potential for one hour. The experiment was performed in a boric acid/borate buffer solution at pH = 8.43 at room temperature
