Description	Journal: Iop Conference Series: Materials Science and Engineering In order to improve the wear resistance and biocompatibility of titanium, which is well known as a common orthopaedic and dental implants material, aluminium oxide (Al2O3)-hydroxyapatite (HA) composite coatings were deposited onto titanium substrate using high velocity oxygen fuel (HVOF) thermal spraying process. The microstructure of the Ti reinforced HVOF coating was investigated by scanning electron microscopy (SEM) and phase identification was performed using X-Ray diffraction techniques (XRD). The surface properties of the titanium substrate before and after $Al_{2}O_{3}$-HA coating deposition in terms of roughness and wear resistance, using pin on disk method, were determined. The obtained results showed that $Al_{2}O_{3}$-HA coatings can extremely improve the wear resistance of the titanium substrate. A higher roughness of the coating evidently has a positive effect onto the adhesion of the implant osseointegration.
