Abstract

With good combination of hardness, ductility, and wear resistance, TiO2 coatings are one of the most potential hard ceramic coatings. TiO2 in an Al2O3 coating had increases the wear resistance which has contributed to an increase in the fracture toughness and decrease in the coefficient of friction. The specific wear rates of pure TiO2 coatings are found to be ranging from 1.62×10-5-4.19×10-5 cm3/N m whereas the Al2O3/TiO2 coatings are in the range of 2.0×10-3 cm3/N m to 28.0×10-3 cm3/N m. This concludes that the TiO2 coatings are most preferable in improving wear resistance.
