Abstract

The invention discloses a porous metal material. The material is a multi-level porous metal material, which is classified according to the pore size of the material, and the number of grading stages is at least two; The elastic modulus of the porous metal material is below 80GPa, and the porosity is not less than 48%. The preparation method is as follows: mixing the raw material powder used to prepare porous metal materials and the pore-forming agent used to prepare the smallest pore cavity to prepare a slurry, uniformly filling the slurry into a polymer material support, forming a green body and drying, The mixed particles are obtained by crushing, and the mixed particles are evenly mixed with the pore-forming agent used to prepare a cavity larger than the smallest cavity to form a dense green body, which is then vacuum sintered, and the conventional follow-up treatment is carried out according to the raw material process. The material has multi-level elastic modulus to meet different use requirements, has good penetration, is especially suitable as a tissue regeneration material, and has a simple and convenient preparation method and is easy to realize.

Description

technical field

[0001] The invention relates to a porous metal material, in particular to a porous metal material with a multi-level pore structure and a preparation method. Background technique

[0002] Porous metal materials, as a new type of engineering material with excellent performance in both function and structure, have been widely used in industries such as metallurgical machinery, petrochemical industry, energy and environmental protection, national defense and military industry, nuclear technology, biopharmaceuticals, and medical equipment. In particular, porous metal materials are widely used in the medical and health industry, especially as implants. Most of the medical porous metal materials that have been used so far are single-pore materials. Compared with the original dense materials, these materials have significantly reduced the overall elastic modulus. The elastic modulus of the prepared porous titanium reported in the literature is 0.1 GPa-30GPa, The el...
