In this study, [Math Processing Error] composite sol coatings on Cp-Ti substrates were deposited by using a sol-gel derived precursor. Prior to hydroxyapatite coating, the samples were micropolished and divided into three sets. The first set was coated with hydroxyapatite (HAp) directly on Cp-Ti. The second set was first coated with intermediate titania layer and then coated with HAp. The third set samples were coated with [Math Processing Error] (50:50) composite sol. Each samples were predried at [Math Processing Error] , and heat treated at [Math Processing Error] . The formation of hydroxyapatite has been confirmed by XRD analyses and the substrate material was found to be oxidized with negligible amount of CaO in the coating. The NaOH treated samples showed the presence of rutile crystal. The SEM studies revealed surface morphologies of each samples. [Math Processing Error] composite sol coating layer was found to be smooth. The bonding strength of each samples were calculated using pull out tests. The bonding strength of the [Math Processing Error] composite sol coating on substrate was 29.35MPa.

Keywords:Hydroxyapatite(HAp) sol;composite sol;Cp-Ti;bonding strength
