Abstract

The invention discloses a preparation method of a pure copper toughened biomedical titanium-based amorphous matrix composite material, which is a biomedical titanium alloy with low modulus, high hardness and high corrosion resistance, and the molar percentage concentration is 90%. ‑95% amorphous matrix plus 10%‑5% Cu composition. Spherical nano-Ti was first prepared by high-energy ball milling 60 Zr 10 Ta 15 Si 15 Amorphous powder; then use electroless plating on spherical nanoscale Ti 60 Zr 10 Ta 15 Si 15 The surface of the amorphous powder is coated with a uniform copper film with a thickness of nanometer scale; finally, these composite powders are sintered into the desired shape by spark plasma sintering (SPS) technology, and a pure copper three-dimensional network skeleton is filled. Composite material with Ti-based amorphous structure. The titanium alloy of the invention not only has the advantages of high strength, high corrosion resistance and low elastic modulus of amorphous materials, but also has the excellent plasticity of pure copper, and is suitable for medical fields such as bone implantation.

Description

technical field [0001] The invention relates to the fields of medicine and chemistry, and relates to a preparation technology of a metal material, in particular to a pure copper toughened biomedical titanium-based amorphous matrix composite material and a preparation method thereof. Background technique [0002] Bulk amorphous alloys are a new type of material that has emerged in recent years. Due to the long-range disorder of atomic arrangement in amorphous alloys, there are no defects such as grain boundaries and dislocations. Compared with corresponding crystalline alloys, amorphous alloys have extremely high strength. , lower elastic modulus, good corrosion resistance and wear resistance. For example, under the same corrosion conditions, Fe-Ni-P-Ca amorphous has better corrosion resistance than stainless steel. In recent years, titanium-based amorphous alloys have become one of the hotspots in the field of amorphous alloy research due to their superior performance and p...
