Abstract

The purpose of this work is threefold: a) to produce both nanostructured Ni-Mo alloys and SiC nanoparticles, and b) to study the corrosion protective properties of the later when used as reinforcing nanoparticles in water-based polymeric paint. After mixing the as-milled powders with paint, it was applied to steel sheets and then exposed to an electrochemical treatment. It was observed that, in the case of silicon carbides, when the carbide content concentration was 4%, the corrosion process in all substrata was directly related to carbon content. On the other hand, carbide contents of 0.5, 1.0, and 2.0% provide good corrosion protection when used in polymeric paints. Also, Ni-Mo alloys had a satisfactory performance as corrosion inhibitors in all cases. The samples were studied by both scanning electron microscopy (SEM) and high-resolution transmission microscopy (HRTEM), and analyzed by energy dispersive spectroscopy (EDX). X-Ray dispersion patterns of the as-milled powders were also analyzed.
