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.

First claim

What is claimed is:

1. A method for forming an information handling system chassis element, the method comprising:
mixing a ceramic material, polymer and a clay into a viscous material;
forming the viscous material into a chassis element shape around a metal portion by injection molding the viscous material into a mold having the chassis element shape and the metal portion;
sintering the injected molded viscous material and metal portion for a predetermined time at a predetermined temperature to densify the viscous material into a multi-layer ceramic chassis element having a metal insert; and
assembling an information handling system with the ceramic chassis element;
wherein the metal portion comprises a hinge portion to couple the chassis element to a separate chassis element.

2. A method for forming an information handling system chassis element, the method comprising:
mixing a ceramic material, polymer and a clay into a viscous material;
forming the viscous material into a chassis element shape around a metal portion by injection molding the viscous material into a mold having the chassis element shape and the metal portion;
sintering the injected molded viscous material and metal portion for a predetermined time at a predetermined temperature to densify the viscous material into a multi-layer ceramic chassis element having the metal portion as a metal insert; and
assembling an information handling system with the ceramic chassis element;
wherein the metal portion comprises a titanium plate and the viscous material comprises aluminum titanate disposed on an upper and lower surface of the titanium plate.

3. The method of claim 2 wherein the titanium plate has a thickness of less than the thickness of each of the upper and lower surface aluminum titanate injection molded viscous material.

4. The method of claim 2 wherein the titanium plate is disposed in a diagonal orientation relative to the injection mold.
