Abstract

The invention discloses a porous niobium-tantalum-titanium alloy material with controllable pore spaces and a preparation method of the porous niobium-tantalum-titanium alloy material. The porous niobium-tantalum-titanium alloy material is prepared from, by atomic percent, 5%-25% of Ta, 5%-25% of Ti and the balance Nb; and a template impregnation method and a powder metallurgy method are combined,the purpose of controlling the porosity, pore diameter and other parameters of porous alloy is achieved by controlling the concentration of an organic adhesive solution and the solid content of impregnation slurry, and therefore the fundamental purpose of controlling the mechanical property and biological properties of an alloy support is achieved. According to the prepared porous niobium-tantalum-titanium alloy material, the porosity is 50%-80%, the open porosity is larger than or equal to 90%, the pore diameter is 47-536 micrometers, the compression strength is 18-122 MPa, the modulus of elasticity in compression is 0.11-2.08 GPa, meanwhile, pore spaces present anisotropic characteristics, and more excellent structure and property simulation performance are achieved compared with traditional porous alloy.

Description

technical field

[0001] The invention belongs to the field of biomedical metal materials, and in particular relates to a porous niobium-tantalum-titanium alloy material with controllable pores and a preparation method thereof. Background technique

[0002] Biomedical materials are mainly used for diagnosing, treating, repairing or replacing the damaged tissues and organs of living organisms or improving their functions. According to the composition and properties of materials, biomedical materials can be divided into biomedical metal materials, biomedical polymer materials, and biomedical inorganic non-metallic materials. At present, the most widely used biomedical metal materials include titanium alloys, stainless steel, and cobalt-based alloys. However, elements such as V, Co, and Al in traditional metal materials have teratogenic, sensitizing and even carcinogenic side effects on the human body. Therefore, β-type alloys with no toxic side effects, better biocompatibility...
