dc.description.abstractIn this study, mechanical and tribological properties of the borided dual-phase alpha + beta type Ti6Al4V titanium alloy were examined. For this purpose, Ti6Al4V alloy samples were borided for 6 h at a temperature of 1100 ? by the powder-pack boriding process. As a result of boriding, a boride layer consisting of TiB2 with a thickness of max similar to 25 mu m and TiB phases with a thickness of max similar to 10 mu m was obtained on the Ti6Al4V sample surfaces. As a result of the boride layer's nanoindentation tests carried out using the Berkovich indenter, it was found to have an elastic modulus of 534.255 GPa and a hardness of 36.537 GPa. Wear tests were carried out using the pin-on-disc method under a load of 10 N and with a sliding distance of 1000 m. Whereas the dominant type of wear in non-borided samples was abrasive wear, oxidative mild wear was generally observed in borided samples. In borided samples, as a result of becoming of surface smoother by hard asperities breaking and increasing the actual contact area, the friction coefficients increased. It was determined that with boriding, the wear performance of Ti6Al4V alloy improved similar to 46.8 times against the Al2O3 counterpart and similar to 4.57 times against WC-6Co counterpart.
