Abstract
A method of forming a skid-proof leather-texture surface on a metallic substrate, including the following steps of: providing a metallic substrate; 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.
