Abstract

Al2O3-metal composite coatings were successfully prepared on carbon steel substrate by self-propagating high-temperature synthesis(SHS) melting-casting means.The effects of transition layers of a bi-layered structure on the interface combination status of the coating were studied in detail,including the microstructure and the elements distribution in the coating.The results show that the coating has an excellent bonding between the substrate and the coating when the content of Al-MoO3 system in the pre-coated transition layer is 30%.Besides,the coating is dense and there is a phenomenon of elements diffusion at the interface.
