Cyclic voltammetry of iron in phosphate solutions of varying pH show mostly active dissolution in acid solutions of 0.1 M H,PO, and NaH,PO,; complete passivity is observed in alkaline 0.1 M Na,HPO, and Na,PO,. The composition of the corrosion film formed in the latter solutions was determined by las
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
