Low-temperature oxidation of steel in neutral media

The effect of adding various corrosion inhibitors on the thickness and prot ective action of magnetite coatings formed on low-carbon steel in neutral a mmonium nitrate solutions was studied. The addition of benzimidazole and be nzotriazole was shown to be most effective. The treatment of an oxidized st eel surface with an IFKhAN-type aqueous passivating composition improves it s corrosion resistance and makes it possible to eliminate the stage of oili ng the coating from the technological chain.
