Production and characterization of metallic biomaterials produced by SHS

NiTi alloy produced by SHS method is used as a biomaterial due to its corrosion performance and biocompatibility. The corrosion resistance and biological properties of NiTi can be improved by hydroxyapatite coating. In this thesis, NiTi alloys were hydroxyapatite coated using hydrothermal method. Different temperatures and dwell times were preferred for surface coating. NiTi alloys in the first group were heated at 180˚C for 24 and 30 hours. NiTi alloys in the second group were heated at 200˚C for 24 and 30 hours. Scanning Electron Microscopy and Energy Dispersive X-ray Spectroscopy were used for microstructural investigations of NiTi alloys.
