Abstract
A method for preparing a porous metal material comprises: in a vacuum environment, volatilizing one or more volatile alloy elements in an alloy, so as to finally form a porous pure metal or a porous alloy. The process method can be widely applied in the fields such as aeronautics and astronautics, atomic energy, electrochemistry, petrochemical industry, metallurgy, machinery, medicines, environmental protection or construction.
Claims18
A method for preparing a porous metal material, comprising:
- volatilizing one or more volatile alloy elements in the alloy in a vacuum environment, so as to finally form a porous pure metal or a porous alloy, wherein the alloy has at least one pore-forming element, wherein the pore-forming element has a higher vapor pressure relative to the basic element of the alloy, and the pore-forming element and the basic element can form the event alloy, solid solution or mixture prepared by powder metallurgy process.
