As I know, NO2- salts and phosphate salts can be used as steel corrosion inhibitors in steel-reinforced concrete structures. I am not very clear about their effect mechanisms. Could anyone recommend references for their effect mechanisms? In addition, they are effective for inhibiting steel corrosion induced by chloride, but are they also effective for inhibiting corrosion induced by low PH value, e.g. carbonation?
