Tribological contact pairs usually encounter solid-solid or solid-fluid interface experiencing thereby surface originated failures through abrasion, erosion and corrosion. To combat these modes of wear and enhance the life, surface depositions like plasma spraying and detonation spraying are being practiced. In detonation spraying the particle undergoing an interaction with combustion flame splashes with high velocity on the substrate; the resultant microstructure of the deposition is largely dependant on the particle velocity and consequent temperature. In the case of plain alumina deposition, the deposition is a layer of lenticulted splats with certain porosity However with alumina-titania composite; the deposition is relatively denser presenting a structure similar to liquid phase sintered. This can influence the tribological response of the ceramic depositions. The present study illustrates the relatively distinct response of detonation sprayed Alumina and Alumina-Titania ceramic composite.
