Abstract
The influence of salts of various phosphonic acids on the chemical passivation of pure iron and mild steel in neutral aqueous solutions by dissolved oxygen has been investigated. Using open circuit potential measurements, current density–potential curves, and impedance spectroscopy it is shown that chemical passivation is not attainable in the presence of phosphonates. Moreover, the passive state of iron or steel surfaces in air saturated sodium benzoate solution can be destroyed by phosphonates.
