Abstract

Alumina–Titania composite coatings are excellent candidates for providing protection against abrasive and sliding wear. These coatings have their applications in textile manufacturing components, tooling, components for the chemical industry and electrical insulation due to high wear resistance, toughness, good grindability and corrosion resistance. Al2O3–TiO2 composite powders having TiO2 from 3 to 40 wt% are deposited on mild steel substrates by advanced detonation spray coating (ADSC) technique, advanced characterization techniques like SEM, FESEM, EDS, XRD, were carried to access the coating characteristics. Tribological behavior of coatings was evaluated under dry sliding wear condition as per ASTM standards, and the results were summarized and correlated with the coating composition.
