Information handling system ceramic chassis
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.
1. An information handling system comprising:
a chassis having a ceramic chassis element, the ceramic chassis element having first and second ceramic layers shaped to support information handling system components, the first layer more ductile than the second layer;
a processor disposed in the chassis; and
memory disposed in the chassis and interfaced with the processor;
wherein the processor and memory cooperate to process information;
wherein the first ceramic layer comprises alumina titanate and the second ceramic layer comprises alumina; and
wherein the ceramic chassis element further comprises an intermediate titanium plate disposed between the first and second ceramic layers.
2. The information handling system of claim 1 wherein the first and second ceramic layers form around the intermediate titanium plate into a contiguous piece through hot pressed diffusion bonding.
3. The information handling system of claim 1 wherein the first and second ceramic layers are formed around the intermediate titanium plate with multistage injection molding.
4. The information handling system of claim 1 wherein the ceramic chassis element has a rectangular shape and the intermediate titanium plate is disposed in a diagonal orientation relative to the rectangular shape.
