摘要:
A method for making patterns on a metal article comprises providing a metal substrate having an outer surface. A light-absorbing coating is formed on selected regions of the outer surface to reduce the surface laser reflectivity of the metal substrate. The selected regions cooperatively have a shape of a desired pattern. The selected regions are treated by laser-quenching, thereby hardening the selected regions. The outer surface is sandblasted, enabling the outer surface besides the selected regions to have a greater surface roughness than the selected regions. A metal article made by the method is also provided.

A method for surface treating plastic products includes providing a plastic substrate; forming a base paint layer on the plastic substrate; forming a flat paint layer on the base paint layer, the flat paint layer made of a flat paint and having an initial specular gloss at 60° geometry of about 5-10; partially masking the flat paint layer; and polishing unmasked portions of the flat paint layer to achieve a specular gloss at 60° geometry of about 80-90. A plastic product made by the present method is also described.
摘要:
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.
摘要:
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.
