Comparison of tensile properties of Ti-Ta alloys and Ti-6Al-4V for biomedical implant application.

Abstract

In medical field, the metallic materials have proven their significance to additive manufacturing allowing the
production of complex geometries of implants accurately. The requirement of such implants is increased due
to increase in accident and also increase in population of aged people. The wide range of materials are being
used or are under development and there is a great scope of improvement. The implant material should have
better wear resistance, corrosion resistance, Young’s Modulus nearer to the bones. The most widely used
material for the implants is pure Titanium and Titanium based alloys. Among them the Ti-6Al-4V has been in
the market since long. Recent research has proven that the biocompatibility of Tantalum is superior than that
of Titanium and its other alloys. Addition of Ta, as an alloying element with Ti improves the mechanical
properties and biocompatibility of the implant. So, this study is intended to check the possibility of Ti-Ta alloy
to be the implant material by comparing the tensile properties to check if Ti-Ta alloys can overcome the
limitations of currently used materials.
