Hydroxyapatite (HA), Al2O3-13 wt%TiO2 (AT) nanoparticles coated on bioactive commercially pure titanium (Cp-Ti) implant were fabricated by plasma spray coating technique. The fabricated monolayer AT, HA film of thickness 75 μm and bilayer (AT/HA) of thickness 150 μm and the coated film surface crystallinity, morphology and phases were investigated in terms of X-ray diffraction, SEM, FT-Raman spectroscopy. In this work, nanostructure AT, HA powders were plasma sprayed on the biomedical Cp-Ti implant surface improve corrosion resistance, and microhardness, surface roughness values compared to uncoated surface. Electrochemical corrosion test was carried out by simulated body fluid (SBF) with ionic concentrations comparable to that of human blood plasma and this result shows that improved corrosion resistance, for the bilayer (AT/HA) coated surface compared to a monolayer AT, HA coated surface. For Al2O3 addition with 13 wt%TiO2 ceramics powder reinforced coating which can act as a barrier for the metal ion released from the implant surface. The in vitro analysis of the bilayer coated implant was good agreement with bone osteoinduction in the biological environment. © 2014 Elsevier Ltd and Techna Group S.r.l.
