Improvement of Ti-based Alloys for the use in Biomedical Applications by employing Laser Treatment

Alloys developed for biomedical applications need to satisfy specific criteria in terms of biocompatibility, resistance to corrosion, mechanical considerations, and ionic cytotoxicity. Although stainless steel, cobalt-based alloys and titanium alloys are all used in biomedical applications, Ti and Ti-based alloys are generally preferred compared to other alloy systems. They have applications inmedical and dentistryfields because of their improved mechanical properties, excellent corrosionbehavior, good biocombatibility, relatively low youngs modulus, light weight and being non-magnetic. However, titanium and its alloys cannot meet all of the clinical requirements. Therefore surface modification and coating are often performed in order to improve their biological, corrosion, and wear properties. In this research proposal, we intended to develop a nanostructured Titanium Alloy for biomedical applications in-house by powder metallurgy process. Afterwards, well intend to improve its surface characteristics using laser surface treatments and laser nitriding. Subsequently, Microstructural assessment will be carried out in addition to performing mechanical, corrosion, wear, and biocompatibility characterization to investigate the effect and improvements of the surface treatments on the desired biomaterials properties.
