Abstract

A heat dissipation mechanism for connecting with at least one heat source includes a main body and at least one heat dissipation block. The main body is made by a material of alloy or metal through a die casting process and has a first side and a second side that are corresponding to each other. The heat dissipation block is disposed on the first side of the main body, made by a first high thermal conductivity material, and having a connecting surface that protrudes outside the main body. The connecting surface directly or indirectly connects with the heat source. The heat dissipation block connects with the main body by means of a first connecting structure, the first connecting structure having a first pair of interlock structures that are disposed in the main body and the heat dissipation block respectively.

Abstract

A method of anodic treatment for a metal workpiece combined with a non-metallic material includes steps as follows. A pretreatment process is applied to the metal workpiece. The metal workpiece is anodic oxidized, and washed with water. Then, the metal workpiece is put in a vacuum environment to evaporate a residual chemical agent between a metal part and a plastic part of the metal workpiece. The metal workpiece is washed with water. An activating treatment is applied to the metal workpiece. The metal workpiece is dyed, and is sealed.

Abstract

A method of fabricating an antimicrobial metal complex surface, and the method includes providing an article, and the article has a first metal complex surface treated by anodization. The first metal complex surface is formed with a first pore. Secondly a silver suspension is provided. The silver suspension also has pore sealing agent. The article is soaked in the suspension to form a pore sealing layer having silver particles on the first metal complex surface such that the silver particles are distributed in the pore sealing layer. The antimicrobial metal complex surface fabricated by the method inhibits microorganism growth on the anodized metal surface.

Abstract

A method of forming a skid-proof leather-texture surface on a metallic substrate, including the following steps of: providing a metallic substrate; roughening the surface of the metallic substrate by performing sand-blasting; performing a first pretreatment to clean the surface of the metallic substrate; etching the surface of the metallic substrate through an etchant while using a etch-moderating agent to moderate the condition of etching performing a second pretreatment, such as pickling or chemical polishing, on the surface of the metallic substrate; performing an anodic treatment on the surface of the metallic substrate to form an oxidized film having micro-porous structure thereon; activating the surface of the metallic substrate after the anodic treatment; dyeing the surface of the metallic substrate; sealing the micro-porous structure formed on the surface of the metallic substrate; and ash-removing to clean the metallic substrate.

Abstract

A method of producing a multicolor surface is described herein. The method includes the following steps: providing an aluminum-based substrate having an outer and inner surfaces; performing a mechanical process on the substrate; forming at least one fixing portion on the inner surface of the substrate; forming at least one conductive hole on the fixing portion; performing a first anodization on the substrate to form a first oxide layer that can be dyed with a first color on the outer surface of the substrate; removing at least some of the first oxide layer from the fixing portion and the outer surface of the substrate; performing a second anodization on the substrate to form a second oxide layer that can be dyed with a second color on the exposed outer surface of the substrate stripped of the first oxide layer; and removing the fixing portion.
