Abstract:
A housing for an electronic device includes a metal substrate and a ceramic coating directly formed on at least portions of the substrate, the coated portions of the substrate having a rough surface. A method for fabricating the housing comprises roughening predetermined portions of the substrate; thermally spraying a ceramic coating on the roughened portions of the substrate, fixing the substrate on a tool having cold water circularly running there within during the thermal spraying; and grinding and polishing the ceramic coating.
Abstract:
A display window is formed by mechanically processing a transparent ceramic article. The composition of the ceramic article includes yttrium oxide and thorium oxide, the mole percentage of yttrium oxide is about 85% to about 94.99%, and the mole percentage of thorium oxide is about 4.99% to about 15%. The display window has a high light transmittance, good acid and alkali corrosion resistance, high hardness, long lifetime.

Abstract:
A housing for a portable electronic device is transparent and U-shaped. The housing includes a first section, a second section opposite to the first section, and a connection portion connecting the first section to the second section.
Abstract:
A stainless steel article is provided. The stainless steel article includes a stainless steel substrate, and a pattern formed on an outer surface of the substrate. The pattern is defined by at least one recess formed on the outer surface. The pattern has a surface roughness of about 50 nm-150 nm. A method for making the present article is also provided.
