Abstract

The invention discloses a biotoxicity-free Zr-based amorphous alloy and a preparation method thereof, and relates to the technical field of amorphous alloys. The biotoxicity-free Zr-based amorphous alloy is composed of the following elements: Zr, Cu, Al, Ti, Fe and Ni, wherein the percentage content of Zr atoms is 56%, the percentage content of Cu atoms is 24%, the percentage content of Al atoms is 9%, the percentage content of Ni atoms is 1-6%, the percentage content of Ti atoms is 4%, and the percentage content of Fe atoms is 1-7%. The Zr-based amorphous alloy has the beneficial effects thatthe defect that common toxic elements Nb, Pb, B and V exist in an existing common Zr-based amorphous alloy and have alloy components which are toxic to organisms is overcome, excellent corrosion resistance and high strength of the amorphous alloy are reserved, and the alloy is low in cost, easy to prepare and wide in adaptability.

Description

technical field [0001] The invention relates to the technical field of amorphous alloys, in particular to a non-biotoxic Zr-based amorphous alloy and a preparation method thereof. Background technique [0002] Amorphous alloys are different from crystalline materials. The long-range disordered structure and the molecules (or atoms, ions) that make up its substance do not show regular periodicity in space, which makes it have unique physical and chemical properties, and there is superplasticity in the supercooled liquid phase region. Phenomenon. [0003] The vast majority of zirconium-based amorphous alloys contain toxic elements Nb, Pb, B and V elements, which makes amorphous alloys still have many shortcomings in biological applications. Application, especially as a biological implant material, as the implantation time prolongs, the toxic elements in the amorphous alloy will have a series of harmful effects on the human body, for example, for long-term implantation, metal ...
