In this work, biomaterials consisting of bioactive hydroxyapatite-based
ceramic and nickel-titanium-magnesium alloys were made. The biomaterials
were obtained through powder techniques involving mechanical milling,
uniaxial pressing and pressureless sintering. The purpose of the study was
to evaluate the effect of alloys on the mechanical properties of
hydroxyapatite, the alloy additions were 0, 20, 30, 40, 40, 50 and 60 wt.%.
The results were compared with cortical bone samples of bovine origin. From
the results, it is possible to comment that, with increasing alloy contents
in the hydroxyapatite, the mechanical properties increase considerably. The
behavior of the composites reinforced with 50 and 60 wt.% NiTiMg alloy is
similar to that of bovine cortical bone. The microstructures of the
biomaterials are fine, homogeneous, and similar to those of bovine cortical
bone. From the study it can be commented that given the mechanical
characteristics of the biomaterials obtained, they could be used as possible
bone implants.
