Effects of elevated temperature on the corrosion resistance of silver–cobalt oxide–titanium dioxide (Ag/Co3O4/TiO2) nanocomposites coating on AISI 1020

Abstract The effects of temperature on corrosion resistance of Silver–Cobalt oxide and Titanium Dioxide (Ag/Co3O4/TiO2) nanocomposite coated AISI 1020 in a high-temperature environment was investigated. The Ag, Co3O4 and TiO2 nanoparticles were individually produced by mixing the salt precursors wit...
