Abstract
Methods for manufacturing a metal foam and a metal foam reinforced back plate may be used to provide high-strength and low weight structural elements in portable information handling systems. A method for manufacturing a metal foam may include selectively adding iridium oxide and ceramic particulate to a light-metal allow to create desired mechanical properties of the metal foam.
Claims9
A method for manufacturing a metal foam, the method comprising:
- preparing a first melt comprising aluminum and lithium;
- preparing a second melt by adding iridium oxide, ceramic particulate, and calcium carbonate to the first melt;
- heating the second melt to evolve gas, wherein a metal foam is generated in the second melt;
- and
- cooling the second melt to solidify a metal foam casting, wherein the metal foam casting has a density of about 0.4 g/cm3.
