Nanoparticulate sol-gel pretreatments as barrier coatings and adhesion promoters for metallic corrosion protection

Abstract

The Spanish University Carlos III de Madrid has developed sol-gel coatings for the corrosion protection of alloys. Sol-gel coatings represent a physical barrier between the metallic substrate and the aggressive environment of exposition and act as adhesion promoters through interfacial bonding. Optimization of the coating’s properties may be easily achivied by changing the processing parameters and formulation of the layer. Interest in licensing the applied patent or technical cooperation with companies that would like to incorporate this technology.
