Abstract

Titanium and hydroxyapatite are two materials of great importance as biomaterials. Both are biocompatible materials used in the fields of medicine and dentistry and provide benefits in different applications. In this study, titanium, hydroxyapatite and carbon nanotube materials were mixed by powder metallurgy method and a hybrid structure was obtained. Each powder was subjected to milling under argon atmosphere in a planetary type of ball mill. The milling process was carried out for 5 hours and a 5:1 ball:powder ratio was used. In addition, 400 rpm milling speed was applied and 10 mm diameter tungsten carbide balls were used. In the milling process, 2 wt.% methanol was added as a process control additive to prevent the powders from sticking to the hopper or ball and to obtain high efficiency from the milling process. In hybrid powders, 2 wt.% fixed hydroxy apatite was added to the titanium matrix material and carbon nanotubes were added at varying ratios (0, 0.5, 1, 1.5, 2 wt.%). The morphologies of the ground powders were examined by scanning electron microscopy. In addition, elemental analyses of the ground powders were performed and interpreted by EDS device. As a result of this study, it was observed that the matrix and reinforcement powders were homogeneously dispersed.
