A method for strengthening a housing comprises the following steps: providing a housing being made of colored glaze and having an initial temperature of about 480&#xb0; C. to about 550&#xb0; C.; and spraying the surface of the housing using a spray solution containing potassium nitrate, potassium silicate, diatomite, and water to create an exterior layer on the surface. The exterior layer contains Kions, and the concentration of the Kions gradually decreases from a maximum value in the area of the outside surface of the exterior layer to zero in the area of the inside of the housing.

A film includes base and a photosensitive layer formed on the base. The photosensitive layer substantially includes a first photosensitive agent, a second photosensitive agent, and a thermosol. The first photosensitive agent is water-soluble. The second photosensitive agent is an aromatic ketone compound or a benzoin ether compound. The method for manufacturing the film and the masking method using the film is also provided.

A method for forming pattern on substrate comprises steps of: providing a metal substrate; amorphousizing the metal substrate to from an amorphous pattern layer in the metal substrate; etching the metal substrate and forming an etching portion in the surface of the metal substrate which is not covered with the amorphous pattern layer. The article manufactured by the method is also provided.

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.

A device housing includes a substrate and a decorative article formed in the substrate. The substrate defines a cutout therein and the decorative article is received in the cutout and bonded with the substrate. The decorative article is a glass article which is formed in the cutout by molding softened glass material into the cutout. A method for making the device housing is also provided.

A method for making a housing of an electronic device includes applying a layer of ceramic powder material to an outer surface of a metal substrate. The layer of ceramic powder material and a top layer of the metal substrate are melted by laser irradiation, forming a ceramic-metal composite coating integrally bonding with the metal substrate when cooled. The substrate with the ceramic-metal composite coating is heated to a peak temperature, maintained at the peak temperature for a desired period of time, and then cooled down to room temperature. The heat treated metal substrate with the ceramic-metal composite coating is then formed into a desired shape.
