| titleOfInvention | A method for preparing metal foam with controllable pore structure |
| abstract | The invention relates to a method for preparing foamed metal with controllable pore structure, belonging to the technical field of foamed metal material preparation, and solves the problem that the pore-forming agent is not completely dissolved out of the foamed metal sample during the molding process of the sintering dissolution method, and the matrix is easily destroyed when the pore-forming agent is dissolved. The technical problem of corrosion, the solution is: use sodium thiosulfate as a pore-forming agent to prepare a foamed metal with a controllable pore structure, design the pore shape, determine the weight of the required sodium thiosulfate particles and metal powder, and prepare the pore-forming agent , powder mixing, cold pressing, pore-forming agent dissolution, drying, sintering, to obtain foam metal with controllable pore structure. The present invention uses sodium thiosulfate as a pore-forming agent, uses 3D printing technology to process plastic molds, can reshape sodium thiosulfate as required, and obtains sodium thiosulfate particles of any shape and structure, so as to prepare prepared sodium thiosulfate particles As a pore-forming agent, by adopting the sintering method, various metal foams with uniform and regular pore structure can be obtained. |
