This paper is done essentially to study results of Alumina (Al2O3), Zirconia (ZrO2) and Alumina-Zirconia (Al2O3+40%ZrO2) ceramic coatings by using plasma spray process, with different coating thickness of 100μm, 150μm and 200μm are deposited on Al-7075T6 substrate. Coating microstructure were characterized by using SEM. The coating Micro hardness, Tribological behaviour and Surface Roughness of the coated specimens were determined for Aluminium (Al-7075T6) and Coated Al-7075T6. NiCrAl is used as a bond coat for providing better coating adhesion. Dry sliding wear test were performed for different sliding distance of 1000m, 2000m, and 3000m at a constant load of 10N by using a Pin-on-Disc. From the above work the results were obtained it showed that, Alumina-Zirconia (Al2O3+40%ZrO2) coated specimens having very good wear resistance property when compared to Alumina (Al2O3), Zirconia (ZrO2) coating materials. These results clearly demonstrate that the significant improvement in coating performance can be achieved by proper thermal spray conditions and proper mixing of coating powder composition.
