Creating hydroxyapatite (HAP) by hydrothermal method in Ti6Al4V alloy surface

Due to the structural properties of titanium and its alloys, it has many advantages over most metals. Especially health, are of great interest in important areas such as automotive and aerospace. For this reason, titanium and its alloys are more widely used in recent years. The increased use of titanium in many areas has increased the research and experimental studies on this alloy. Coatings made on the surfaces of titanium and its alloys protect the material against environmental influences and increase its strength. In this thesis, hydroxyapatite was formed by hydrothermal method on the surface of six Ti6Al4V alloy samples. The surfaces of Ti6Al4V alloys were pretreated using the sanding method. The obtained samples were surface coated using hydrothermal method which is one of hydroxyapatite methods. When the surface is covered, different temperature and time values are applied for each sample. Experimental study was carried out by separating the six samples into two groups. The three samples in the first group were heated at 180°C for 18, 24 and 30 hours, respectively. The three samples in the second group were heated at 200°C for 18, 24 and 30 hours, respectively. Scanning Electron Microscope, X-Ray Diffraction and Atomic Force Microscopy devices were used for the microstructure studies of the obtained samples. The effect of temperature and time parameters was examined by comparing the analysis results of each sample.
