Method for producing porous metal with micro-holes

摘要

A method for producing porous metal with micro-holes comprises the steps of selecting a base material, sintering or smelting, removing the filling material, washing, drying and reduction. The base material is selected from pure metal and alloy powder for sintering or casting. The filling material is fine powder solvable in water or in alkaline solvents. The sintering step further includes steps of mixing and metal powder metallurgy. The casting utilizes high or low waves to fuse the base material particles. A selected solvent removes the filling material in the raw metal bulk produced in the sintering or casting step, and a product of porous metal with micro-holes is formed.
