Titanium-zirconium alloys may be the preferred choice for load-bearing
biomedical materials due to their excellent mechanical properties; in addition,
these metal biomaterials are bio-inert. In this work, the Ti50Zr50 alloy has been
synthesized with different atomic percentages of graphite, through an electric
arc furnace, in order to improve its mechanical properties. As a consequence,
alloys that presented TiC distributed in the metallic matrix were obtained with
which microstructural investigations and hardness measurements were carried
out. X-ray diffraction analysis confirms that the alloys retain the initial phase
even after the addition of carbon. The optical microscopy allowed us to observe
a refinement of the grain size of the base alloy (Ti50Zr50). Finally, it was observed
that the TiC distributed in the metallic matrix of the Ti50Zr50 alloy generated by
the incorporation of the graphite which makes the alloy harder, which is
determined as an improvement in its mechanical properties.
