Problems solved by technology

First of all, due to the application of titanium-based alloys in the biomedical field, especially as a biological implant material, as the implantation time prolongs, the Ti-Cu-Ni or Ti-Ni-based amorphous titanium alloy The metals Ni, Cu and Al in it will have a series of harmful effects on the human body. For example, after long-term implantation, the metals Cu and Ni will cause cytotoxicity and neurotoxicity to the human body, and Al may cause symptoms such as senile dementia.

Abstract

The invention provides a biological medical non-crystal titanium alloy and a method for preparing the same, and relates to the field of biological medical titanium alloy. The titanium alloy mainly comprises the following components in atom content percentage: 49.5 to 91 percent of Ti, 3 to 20.5 percent of Zr and 6 to 30 percent of Si; or the titanium alloy also comprises Fe, and the composition of the titanium alloy is Ti-Zr-Si-Fe; or the titaniumalloy also comprises Fe and Mo, and the composition of the titanium alloy is Ti-Zr-Si-Fe-Mo; or the titanium alloy also comprises Fe, Mo and Nb, and the composition of the titanium alloy is Ti-Zr-Si-Fe-Mo-Nb. The biological medical non-crystal titanium alloy removes toxic elements of Ni, Cu, B, Al and / or V existed in the prior biological medical non-crystal titanium alloy, thereby greatly reducing the damage of the implantation material to human tissues; moreover, the biological medical non-crystal titanium alloy also has quite excellent corrosion resistance.

Description

technical field [0001] The technical solution of the invention relates to a biomedical titanium alloy, specifically a biomedical amorphous titanium alloy and a preparation method thereof. Background technique [0002] Due to its excellent biocompatibility and bioactivity, titanium alloy has always been a popular research object in the field of biomedical materials at home and abroad. CN101081311 discloses a biomedical β-titanium alloy material; CN101081312 discloses a biomedical β-titanium alloy material; CN1490422 discloses a β-type titanium alloy for surgical implants. All the above-mentioned documents disclose biomedical crystalline titanium alloy materials. [0003] With the rapid development of material science, it has been found that amorphous titanium alloys have higher strength and better corrosion resistance than crystalline titanium alloys, and have superior performance and potential value in the application of biomedical materials. Therefore, in recent years, am...
