Various surface modifications technologies are now available. Among them, thermal spraying, which refers to a family of material deposition techniques has emerged as an important tool for achieving tailor made engineering surfaces. In the light of the above, present investigation is aimed at developing plasma sprayed Titania coatings on Al6061 substrate and to evaluate its slurry erosive wear resistance. Titania powders were thermally sprayed on Al6061 substrate by Atmospheric Plasma Spray process. The developed coatings were subjected to slurry erosive wear tests in 3.5% NaCl solution with sand as erodent. The slurry erosive wear resistance of developed coatings are higher than that of uncoated substrate under identical test conditions owing to the increased hardness on coating.
