Popis: | It is shown that the multimolecular protective layer of an organic inhibitor formed on the surface of chromium–nickel steel in an HCl solution containing a triazole derivative, the inhibitor IFKhAN-92, has a protective aftereffect in background solutions of the same acid. Such a protective layer is chemically bonded to the Fe, Cr, and Ni oxide and hydroxide phase adjacent to the metal phase. The lower part of the polymolecular protective layer of the organic inhibitor consists of a polymer complex formed by IFKhAN-92 molecules, metal cations (Fe, Cr, and Ni), and chloride anions, and the outer part consists of physically adsorbed IFKhAN-92 molecules, which are easily removed from the metal surface during ultrasonic washing of samples. |
