Abstract
An electro-thermally re-solidified layer formed by powder mixed-electrical discharge machining (PM-EDM) on the surface of titanium alloy Ti-6Al-4 V has different properties than the original material. In our research, we studied the mechanical properties and surface integrity of the re-solidified layer based on the characteristics of the heat source distribution. For this purpose, we used Thermo-Calc software to predict the phase transition of Ti-6Al-4 V material properties based on thermography and surface topography data. In our work, we investigated the corrosion behavior of Ti-6Al-4 V and considered the changes in primary and secondary phases. We observed the formation of TiOx in our experiment, which enhanced the surface’s corrosion resistance, biocompatibility, and bio-functionality of Ti-6Al-4 V. Our finding demonstrates that TiOx can be used in surgical equipment and odontological implants.
