The hybrid nanocomposite of alumina-titania (Al2O3 - TiO2) is a material with unique features that make it a good possibility for coatings that inhibit corrosion and wear. This nanocomposite is composed of Al2O3, TiO2, and third-phase particles. Introducing a third phase, such as carbon-based material or oxide ceramic, into an Al2O3-TiO2 composite in a ternary system drastically changes the composite's properties. These three combination materials result in nanocomposites with increased hardness, wear resistance, chemical resistance, and thermal stability. The spraying technique is commonly used to deposit Al2O3-TiO2 hybrid nanocomposites to coat a metal substrate. The microstructure, porosity, and mechanical properties of the nanocomposite feedstock determine the quality of the decorated substrate. The properties of the nanocomposite can be adjusted by modifying the composition and size of the nanoparticle. Al2O3-TiO2 hybrid nanocomposites with tertiary materials show great potential as a novel material with various possible uses in metallic coating. A new, unique ternary system, as well as improved coating properties in Al2O3-TiO2 hybrid nanocomposites, require more exploration.
