Bioactivity of Rolled Titanium

Mahapatra, Deepshikha (2015) Bioactivity of Rolled Titanium. BTech thesis.



Metals have found wide applications in the field of implant fabrication for the replacement of human hard tissues. Titanium being biocompatible, possessing the high strength to weight ratio, having low density, low modulus and showing ease of fabrication is the new implant material. This study gives the microstructural characterization of conventional rolled titanium (Ti) deformed by cold rolling. The Ti samples were then characterized by optical microscopy, X-ray diffraction, Vickers hardness measurements, contact angle measurements and tensile test. In addition, in vitro bioactivity of the Ti samples was carried out in simulated body fluid (SBF) for 28 days. Protein adsorption was also studied using bovine serum albumin (BSA). Rolling has induced an increase in hardness, protein adsorption and tensile properties. X-ray powder diffraction (XRD) analysis shows the diffraction pattern of the samples corresponding to titanium along with those that correspond to apatite after bioactivity study in SBF. The abovementioned properties are basic pre-requisites for bone-implant applications. Hence, from this study it can be concluded that the rolled Ti is a suitable biomaterial for biomedical applications.
