Surface modification of Ti6Al4V was studied by thermally oxidizing the sample at temperature 750°C for 12,24 and 36 hrs of time duration for obtaining an oxide film possessing the properties of both anatase and rutile form. Phase characterization analyzed by XRD, morphological features
assessed by SEM and the bio-activity of the surface of thermal oxidation treated and untreated samples through in-vitro test by soaking the samples in HBSS(SBF) for 40hrs and 80 hrs and observing the results with the help of SEM. The measurement taken by XRD indicated the presence of anatase and rutile in samples treated for 12hrs and 24hrs. SEM observation reveals the nature of oxide that longer is the duration the higher is it’s crystallinity and greater thickness (the thickness of 36 hr treated sample is almost twice the 24hr one) due to nucleation and agglomeration. The treated samples immersed in SBF shows better apatite formation than the untreated ones as observed by SEM images.
