Abstract
An information handling system chassis is built at least in part from ceramic elements. For example, a transparent aluminum oxide ceramic portion covers a touchscreen to provide a rigid outer surface for accepting end user inputs. As another example, a ceramic chassis element has a ceramic material formed around a metal material of similar substance with bonding of the ceramic to the underlying material enhanced with oxidation of the outer surface of the metal material.
Claims3
An information handling system comprising:
- a processor operable to process information;
- memory interfaced with the processor and operable to store the information;
- a chassis, the processor and memory contained in the chassis, the chassis having at least one ceramic chassis element comprising a sheet of a first metal having an oxidized outer surface and a ceramic oxide of the first metal disposed over the oxidized outer surface;
- and
- copper disposed over the ceramic chassis element, the copper treated with microarc oxidation of sodium aluminum oxide.
