- Аннотация: Methods for preliminary modification of the surface of structural metals with formulationsbased on organosilanes, including both solutions of individual organosilanes and two-componentmixtures consisting of two organosilanes or an organosilane with an organic corrosion inhibitor, havebeen developed. As a result of this modification, a self-assembling siloxane polymeric/oligomericnanoscale layer is formed on the metal surface. Such layers are capable of changing the physicochemical properties of the metal surface, in particular reducing the susceptibility of the metal tocorrosive destruction. In this work, the mechanism of formation of organosilicon nanolayers andtheir effect on the electrochemical and corrosion behavior of metals have been studied in detailby a set of electrochemical methods, while laboratory studies and accelerated corrosion tests ofcarbon steel and zinc, modified with formulations based on organosilanes, have been carried out.The greatest inhibitory effect is demonstrated by two-component modifying formulations, namelymixtures of vinyl with aminosilane and vinylsilane with benzotriazole. The mechanism of corrosioninhibition by surface nanolayers formed upon surface modification with two-component mixtureshas been considered.
