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 reinforced back plate for use in a portable information handling system, comprising:
- forming a back plate having a relief pattern;
- cementing a metal foam structure corresponding to the relief pattern to the back plate using an adhesive to form the metal-foam reinforced back plate;
- and
- sintering the metal-foam reinforced back plate under an inert gas at 600° C., wherein at least a portion of the metal-foam structure is diffusion bonded with the back plate,
- wherein the metal foam structure comprises:
- aluminum base metal with lithium;
- iridium oxide;
- and
- ceramic particulate,
- wherein the metal foam structure has a density of about 0.4 g/cm3, and wherein the back plate is a metal plate.
