| Abstract | ||
| This research shows the development of a composite material with an alumina matrix reinforced with different percentages of titanium (0.0%, 0.5%, 1%, 2% y 3%) with the intention of analyzing their mechanical and biocompatible properties for its possible application as a biomaterial. Alumina was synthesized using the reaction bonding aluminum oxide (RBAO) methodology. The powders resulting from the milling process had a size distribution ranging from nanometers to 2 microns. By means of X-ray diffraction and differential thermal analysis, it was determined that aluminum oxidizes in both solid and liquid states. It was also found that the alumina formation reaction is complete at 900°C. Using scanning electron microscopy, it was determined that the microstructure has fine grain sizes and homogeneous morphology. Likewise, the elastic modulus and fracture toughness of the composites obtained were determined, results indicate that these properties are higher than the properties of cortical bone. In addition, bioactivity was promoted using the biomimetic method. The results obtained demonstrate that the resulting composite can be used as a biomaterial. | ||
