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.

结果表明，在含三唑衍生物的HCl溶液中，铬镍钢表面上形成的有机抑制剂的多分子保护层（抑制剂IFKhAN-92）在相同酸的背景溶液中具有保护性的后效应。这样的保护层化学键合到与金属相相邻的Fe，Cr和Ni的氧化物和氢氧化物相。有机抑制剂的多分子保护层的下部由IFKhAN-92分子，金属阳离子（Fe，Cr和Ni）和氯离子形成的聚合物配合物组成，外部由物理吸附的IFKhAN-92组成。分子，在超声波清洗样品过程中很容易从金属表面去除。
