ABSTRACT

HAp/Al2O3 composite coating was fabricated onto micro-arc oxidized titanium substrate using a combination of electrophoretic depo-sition and reaction bonding process. SEM, EDS and XRD were employed to characterize the titanium substrate and as-prepared coat-ings. The interfacial bonding strength of the sintered composite coating was tested by shear strength testing experiment. Results show that the green form composite coating can be easily sintered with no cracks and de-composition at 850℃, the bonding strength to the substrate is significantly improved com-pared with the single HAp coating.
