Description

technical field [0001] The application relates to the technical field of titanium-zirconium alloys, in particular to a processing technology for improving the mechanical properties of titanium-zirconium alloys, titanium-zirconium alloys and dental implants. Background technique [0002] With the development of clinical technology, implant materials have become an important part of biomaterials. Titanium and titanium alloys are proven to have excellent mechanical properties, corrosion resistance and biocompatibility, making them the most used dental implants in the world. Pure titanium is the earliest and most widely studied material because of its excellent properties. However, the mechanical strength of pure titanium is not enough, which limits its service life. In order to make up for its defects, researchers have studied various titanium alloys to find materials with better performance than pure titanium, such as Ti-6Al-4V, Ti-Zr, Ti-Mo, Ti-In, Ti-Nb, etc. Studies have...
