Corrosion resistance of stainless steel coated with sol–gel silica

Using sol–gel processing it was possible to obtain composites formed by AISI 304 steel and silica coatings. Based on RBS data, an intermediate layer between the silica and the steel substrate is formed. Such composites increase chemical resistance of stainless steels either in a 1 N H 2 SO 4 or 3.5% NaCl, when compared to steels with no coating.
