Problems solved by technology

[0004] Most of the currently used bone drills are made of stainless steel, containing more Ni elements, which are highly toxic to the human body and have low strength, especially for small-sized stainless steel bone drills. When impacting and rubbing, it is easy to appear blunt edge, bending and other phenomena, the efficiency of bone drilling is low, which increases the pain of patients and may even lead to medical accidents

Abstract

Relating to a biomedical alloy and a processing method for the alloy product, the invention provides a Ti-based amorphous alloy and a method for making a bone drill from the alloy. The invention aims to provide a Ti-based amorphous alloy that does not contain toxic elements and has high elasticity, deformability and torsional strength. The Ti-based amorphous alloy includes Ti, Cu, Zr, Ni, Si, Sn, and SC seven elements, and the seven elements are proportioned by mass according to the general formula of (Ti46.5Cu34.5Zr8.5Fe3.5Sn3Si4)100-xScx, wherein x is greater than or equal to 1 and smaller than or equal to 2.5. The method for making the bone drill from the Ti-based amorphous alloy comprises the steps of: material taking, smelting, melting, suction casting, and finish machining.

Description

technical field [0001] The invention relates to a biomedical alloy and a processing method of the alloy product. Background technique [0002] Amorphous alloy is a new type of alloy prepared by rapid cooling. Its atoms are arranged in a topologically disordered state in three-dimensional space. There are no defects such as segregation, fluctuation of the second equal composition, etc., and the constituent atoms maintain short-range order in the range of several lattice constants, forming a structure similar to atomic clusters. At the same time, no crystallization occurs during rapid solidification, so it has an atomic arrangement structure similar to that of a liquid. It is precisely because of the special atomic structure of amorphous alloys that determine its special physical and chemical properties. Compared with traditional crystalline materials, amorphous alloys have high strength, high hardness, low elastic modulus, high wear resistance and High corrosion resistance....
