Abstract
The passivating power of the aqueous solutions of certain trialkoxysilanes towards low-carbon steel has been studied. It has been established that aminoalkoxysilanes, as opposed to vinyltrimethoxysilane, are capable of passivating low-carbon steel in a neutral chloride-containing buffer solution. Aminoethylaminopropyltrimethoxysilane induces the passivation of steel most effectively. Its adsorption on the reduced or oxidized surface of the St3 steel studied via an ellipsometric method can be adequately described by the Frumkin equation.
