Metallic corrosion is the result of a complex physico-chemical interaction of a metal surface with its surroundings. It may be prevented by separating the metal from the environment by an impervious barrier applied on the metal surface. Because of its physico-chemical nature, the corrosion process also may be affected by treating the metallic surface to alter its activity; this is the basic idea of corrosion inhibition. The effectiveness is discussed of polymeric and monomeric inhibitors and coatings which were gravimetrically tested on mild steel specimens in the environments of 1.0 H-HCl and aerated artifical seawater. Ionizing irradiation for crosslinking and grafting inhibitors and coatings was chosen to enhance inhibition. A comparison of the protective abilities of the various polymeric inhibitors is given in tabular form. It appears that in acid solution, inhibitors with the hydroxyl group in the molecule were substantially less effective than those with the amino group. The effectiveness of irradiated polymeric coatings in seawater also is shown by tabular data. (30 refs.)
