The present work deals with the investigation of the corrosion and sliding wear behaviour of detonation gun sprayed (DG) conventional and nanostructured Al2O3-13TiO(2) coatings deposited on a biomedical grade Ti-13Nb-13Zr alloy. The microstructure and phase composition of the coatings were characterised by scanning electron microscopy (SEM) and X-ray diffraction ( XRD). Hardness measurements were carried out using a Vickers hardness testing machine. The experimental results suggested that the nano structured Al2O3- 13TiO(2) coating exhibited 43 and 33% increase respectively in corrosion and wear resistances compared to the conventional Al2O3-13TiO(2) coating. This improvement in the above properties of nanostructured Al2O3-13TiO(2) coating is due to the presence of larger volume fraction of nanosized particles and lower porosity attained by spraying using DG.
