Titanium and hydroxyapatite materials have great potential for different applications in the
field of biomaterials. The mechanical strength of titanium and the biological similarity of
hydroxyapatite allow the development of effective and reliable biomaterials that can be used
in various health fields. In this study, Titanium was used as a matrix material. Hydroxy apatite
and carbon nanotube were added as reinforcement materials to strengthen the matrix.
Hydroxy apatite was added to all samples at 2 wt%, while carbon nanotube material was
added at varying ratios (0, 0.5, 1, 1.5 and 2 wt%). The process of adding reinforcement
particles to the matrix material was carried out by powder metallurgy method. The matrix and
reinforcement materials were mixed in a planetary type high energy ball mill under argon
atmosphere with a rotational speed of 400 rpm for 5 hours. In addition, tungsten carbide balls
with a ball to powder ratio of 5:1 and a diameter of 10 mm were used in the mixing process.
The mixed powders were sintered by hot pressing method at 600 °C under 600 MPa pressing
pressure for 3 hours. The sintering process was carried out under argon atmosphere. The
morphology of the produced hybrid powders was examined by scanning electron microscopy.
Elemental analysis of the hybrid powders was carried out by EDS device. X-ray diffraction
analyses of hybrid nanocomposite powders were also performed and discussed. Finally, the
hardness of the sintered hybrid nanocomposites was measured by Brinell hardness. The
highest hardness value of the hybrid nanocomposites is 631 HB.
