摘要

Plasma sprayed coatings are widely used as wear resistant coatings on a variety of metallic substrates. Alumina (Al2O3), Titania (TiO2) and Alumina-Titania (Al2O3+40%TiO2) ceramic coatings with different coating thicknesses of 100μm, 150μm and 200μm are deposited on Al-6082T6 substrate by Plasma Spray Technique. Microstructural, Tribological Properties and Surface Roughness of the coated specimens have been studied for Aluminium (Al-6082T6) and Coated Al-6082T6. NiCrAl is used as a bond coat material to promote coating adhesion. Dry wear test was performed for different sliding distance of 1000m, 2000m, and 3000m at a constant load of 10N by using a Pin-on-Disc. The results obtained from the above work showed that, the Alumina coated specimens is having excellent wear property when compared to Titania and Alumina-Titania coating materials. The SEM of the worn surfaces of coated specimen shows better results than that of the Al-6082T6.
