Background: Ti and its alloys have been widely used as orthopedic and dental implants due to their outstanding mechanical properties and biocompatibility. However, long time is required to form bond between Ti implant and surrounding tissues. Therefore, these implants necessitate surface treatment such as mechanical/chemical treatment and coating of bioactive materials for improving the osseointegration. Results: This study was focused on the calcium-phosphate (Ca-P) coating on machined Ti, blasted-Ti (B-Ti), and blasted-NaOH-etched-Ti (BNH) surfaces by hydrothermal method to evaluate the ability of HA formation. Nanostructured morphology was created by NaOH etching on blasted-Ti surface. XRD analysis confirmed the existence of sodium titanate phase on such samples. Rutile and anatase phases along with hydroxyapatite were observed after hydrothermal treatment in Ca-P solution. Substantial hydroxyapatite together with TiO2 was observed during hydrothermal treatment at 200°C for 12 hrs. Blasted-NaOH-etched samples (BNH-Ti) revealed appreciable bone-like apatite formation as compared to machined-Ti and blasted-Ti (B-Ti) surfaces. However, maximum HA formation was confirmed on Ca-P coated-BNH samples (BNHA-Ti-200-12) by XRD and ICP analysis. Conclusion: Multistep surface treatment adopted in current study would be effective to enhance HA formation on Ti surface.
