Abstract

The effect of some phosphonic acids (HMEP, NTMP, HEDP) on the chemical passivation of iron by dissolved oxygen in neutral aqueous solutions has been investigated. It has been shown that in the presence of phosphonic acids chemical passivation cannot be attained. This effect is due to the formation of soluble complexes as could be shown by the stability constants determined.

Iron passivated chemically in chromate solutions over a range of pH was electrochemically reduced in phosphate-borate buffer solution of pH 8.5. According to the chronopotentiometry, the passive fllm became thinner as the pH diminished, which was in agreement with the ellipsometric result. The rest
