Several studies indicate that Titanium and its alloys are materials with high
affinity to be used as human bone substitutes. However, despite its excellent
characteristics as biomaterial, due to its bioactivity and biocompatibility, there
have been cases of rejection, so it is convenient to treat the material. The affable
features are: porosity and mechanical properties, such as: specific weight and
elasticity modulus, close to those of human bone.
From mesh powder -325mm, monoliths of 10 mm diameter and 7 mm high with
different porosity, were generated using pulsed power assisted in a sintering
equipment. A medium spacer was manipulated to generate the different levels
of porosity. The behavior of the variables in the two stages of the sintering
according to the proportion of Titanium and spacer was analyzed. In addition,
cell structures were characterized by SEM, XRD and Nanoindentation.
It was observed that the materials synthesized by this technique show better
mechanical properties. In addition, smooth cellular structures with
interconnected porosity can be obtained in a controlled manner, which suggests
the possible obtaining of biomaterials with characteristics similar to those of
human bone.
