TiO2 has a lower melting point than Al2O3, a lower Mohs hardness value than Al2O3, and molten TiO2 exhibits better wettability on metal substrates such as steel, titanium, and aluminum compared to molten Al2O3, resulting in superior bonding performance.
Due to the reduction of TiO₂ in the high-temperature plasma spray jet, TiO₂ coatings exhibit semiconductor properties. In Al₂O₃-TiO₂ composite powders, when the TiO₂ content exceeds 20%, the Al₂O₃-TiO₂ coating demonstrates semiconductor characteristics.
