- Аннотация: Abstract: The mechanism of the vapor–gas deposition of vinyltrimethoxysilane (VS) and ethyleneglycol (EG) from azeotropic solutions is investigated, which allows a reduction of the evaporationtemperature of the components of working mixtures. The need for such studies is associated withthe development of a new direction in the technology of vapor–gas deposition of polymer coatings.Methods have been developed for monitoring the chemical composition of working solutions inevaporators using optical spectroscopy, which makes it possible to calculate the partial pressures ofvapor-phase components. Based on these studies, compositions of working solutions are proposedthat allow the equalization of the partial pressures of the components of working mixtures with a largedifference in the boiling point. With the aid of vapor–gas deposition, siloxane coatings on low-carbonsteel were obtained, the protective properties of which exceeded the treatment with volatile inhibitorsof the adsorption type by two to three orders of magnitude. A new method of vapor–gas depositionof non-volatile powder inhibitors on metals is proposed. Chemical compositions of siloxane coatingswere determined using XPS, and mechanisms of interaction of VS with the polymerization promotersethylene glycol and 1-hydroxy ethylidene-1,1-diphosphonic acid (HEDP) were proposed.
