Abstract
Embodiments of the present technology include metal foams and methods of manufacture. An example method of creating a porous metal foam includes mixing an amount of a metallic powder with an amount of sacrificial particles in a specified ratio to create a mixture; and applying pressure to the mixture that is sufficient to: compact the mixture; decompose or dissolve the sacrificial particles; and fuse the metallic powder into the porous metal foam.
Claims15
A method of creating a porous metal foam, the method comprising:
- mixing an amount of a metallic powder with an amount of sacrificial particles in a specified ratio to create a mixture;
- applying pressure to the mixture that is sufficient to:
- compact the mixture;
- decompose or dissolve the sacrificial particles;
- and
- fuse the metallic powder into the porous metal foam;
- filling voids of the porous metal foam with a polymer;
- and
- implanting magnetic nanoparticles into the polymer.
6 more elements
A method, comprising:
- providing a mold having a cavity;
- placing or direct three-dimensional printing of sacrificial particulates in the cavity of the mold in such a way that a matrix is formed having voids;
- applying pressure to the sacrificial particulates while the sacrificial particulates are inside the cavity;
- depositing a metal onto the sacrificial particulates using any of chemical vapor deposition, physical vapor deposition, or electroless or electrolytic plating;
- vaporizing the sacrificial particulates or diluting the sacrificial particulates with a chemical solvent to reveal a metal foam;
- and
- fusing the sacrificial particulates using any of heat or a chemical solvent.
