The evaluation of the structure and hardness of dental Ti-Zr alloys

Many types of alloys are available as dental implants, but titanium and its alloys have been widely used due to their outstanding properties. In this research titanium alloys with different Zr contents were prepared by arc-melting. Phase identification was performed by XRD analysis. Microstructure was observed by light microscope after etching in two solutions. Detailed microstructural observations were realized by SEM and EDS. Vickers hardness measurements were performed as well. Alloy with higher Zr content shows nearly beta-phase structure and more adequate hardness values for dental implants than alloy with lower Zr content.
