Some Nitrogen Compounds as Corrosion Inhibitors for Steel in Acidic Solution
Author(s): Diab A, Abd El-Haleem SM
The loss in weight of steel is set in acid solutions in presence of chloride and sulphate anions as aggressive ions and urea, phenylhydrazine and o-phenylenediamine as inhibiting compounds. The loss in weight will increase with the increasing concentration of chloride and sulphate ions and on raising the temperature of solution. The inhibition potency of the studied inhibiting compounds will increase within the order: urea>phenylhydrazine>o-phenylenediamine.
