Abstract : A systematic investigation on the fracture toughness measurements of plasma sprayed alumina-13 wt% titania coatings by microindentation technique was carried out. The enhancement in the adhesive strength of the as plasma sprayed coatings was observed when tested with a newer technique of adhesive/cohesive strength measurement developed exclusively for thinner coatings of thickness less than 380 ms. The testing method apparently conform the modified version of the ASTM D-3359-B crosshatch testing methodology.
