Development of porous TiO2 layer on Ti6Al4V for bone implants.

Kumar, Ravi (2014) Development of porous TiO2 layer on Ti6Al4V for bone implants. BTech thesis.



Titanium and its alloys are among widely used biomaterials, particularly in the field of orthopedics and osteo-synthetic implants. Adhering properties of cells and proteins of the body system on these implants are dependent upon surface chemistry as well as surface morphology of the biomaterial used for making the implant. Anodization is a simple, cost-effective, eco-friendly and a promising technique for surface modification. It paves a controlled path to create nano-level roughness and also nano-level features. Surface modification of Ti6Al4V was studied by anodizing theTi6Al4V alloy samples. Morphological feature was assessed by optical microscope, phase characterization was analyzed by XRD, and the wettability property of the anodically oxidized surface was assessed by contact angle method. The phase analysis carried out by XRD indicated the presence of anatase and rutile in oxidized samples. The oxidized layer was found to be hydrophilic and mechanically stronger than the substrate itself.
