## 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 th
The kinetics of passivation of Fe in pH 8.4 borate buffer solution at 0.0 V have been studied in both the presence and absence of 0.5 M Cl-. Cl-has no influence on the decay of the passive current with time over the course of several hours. Oxide films were examined by AES and SIMS for possible Clin
