In an attempt to increase the bioactivity and corrosion resistance of a Ti–6Al–4V alloy, the thermochemical process for surface modification was utilized. Ti6Al4V substrates were pretreated with a sodium hydroxide (10 M of NaOH aqueous solution at 60°C for 24 h.). After NaOH pretreatment, a three- dimensional porous network of hydrogel layer made of sodium titanate was observed on the Ti6Al4V surface. The gel can then be converted to Ti-OH groups during hydrothermal treatment, which will contribute to the formation of hydroxyapatite when immersing them in a simulated body fluid (SBF) solution for 30 days. Characterization was performed by means of X-ray diffraction (XRD), attenuated total Reflectance-Fourier transform infrared spectroscopy (ATR-FTIR), Scanning electron microscopy (SEM), and energy dispersive X-ray analysis (EDX). The resultant apatite layer formed on titanium metal in SBF could enhance the bonding strength between living tissue and the implant.
