Vapor-phase deposition of polymer films based on silanes for corrosion protection of AMg3 aluminum alloy
https://doi.org/10.61852/29493412202422108121
Abstract
Silicone primers based on silanes are often used to increase adhesion between the metal surface and the paint coating. At the same time, it is possible to apply polymer films from organosilanes using vapor phase deposition. This method makes it possible to obtain uniform thin polymer layers with high barrier properties. In this work, the adsorption and polymerization of vinyltrimethoxysilane on the surface of the AMg3 aluminum alloy in the presence of water vapor and ethylene glycol was studied. It has been shown that ethylene glycol is an effective promoter of polymerization due to crosslinking of hydroxyl and ethanol groups during the polycondensation of silane and ethylene glycol molecules on the metal surface. Using X ray photoelectron microanalysis and corrosion electrochemical methods, the protective properties of the resulting polymer films and their interaction with the initial surface of the AMg3 aluminum alloy and oxidized in the converting composition IFKhANAL-2 were studied. It has been shown that impregnation of oxide coatings with organosilanes using the vapor phase deposition method significantly increases their corrosion resistance.
