Abstract

HAp/Al₂O₃ composite coating was fabricated onto micro-arc oxidized titanium substrate using a combination of electrophoretic deposition and reaction bonding process. SEM, EDS and XRD were employed to characterize the titanium substrate and as-prepared coatings. 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 decomposition at 850degC, the bonding strength to the substrate is significantly improved compared with the single HAp coating.
