Abstract

The aim was to investigate the corrosion behavior of steel 12Kh18N10T in tetrachloroethylene (C//2Cl//4) and tetrachloropropylene (C//3Cl//6) in relation to the moisture content of the chlorocarbons, heat treatment of the metal, and metal surface. The sequence inducing cracking is: adsorption of dissolved water in the chlorocarbon on the metal surface; hydrolysis of the chlorocarbon with formation of acid products; formation of electrolyte in a thin film of moisture; penetration of chloride ions into the film and development of corrosion beneath it; inception and development of a crack.
