dc.description.abstractIn present work an attempt has been made to enhance mechanical properties of plasma sprayed hydroxyapatite coating by addition of 10 wt% aluminum oxide. A bond coat of Al 2 O 3 -13TiO2 has been applied to improve strength of hydroxyapatite composite coating. Mechanical properties of coatings with addition of alumina and with incorporation of bond coat have been investigated in accordance with the ASTM C 633-79. Results indicate that the tensile bond strength of hydroxyapatite coating increased by 13 per cent by alumina reinforcement and 25 per cent by both reinforcement and application of bond layer respectively. The area of adhesive failure was found to decrease for hydroxyapatite-Alumina composite coating and hydroxyapatite composite coating with bond coat as compared to pure hydroxyapatite coating. The microharness of specimens was found to increase with reinforcement, however the highest hardness was recorded for bond coat. The microhardness was found to decrease with distance from substrate coating interface. © 2012, DESIDOC.-
