Abstract
The anodizing treatment of metal base surface includes the following steps: anodizing treatment to form oxide film on the surface of metal base; laser carving or etching to eliminate partial oxide film; secondary anodizing treatment; and repeating the last mentioned two steps. Through the said anodizing treatment, colorful and grainy stereo pattern may be formed on the surface of the metal base.
Description
[technical field]
The present invention relates to a kind of anode treatment method of metal base surface, be meant a kind of anode treatment method that forms multicolour, many lines texture or stereo pattern at metal base surface especially.
[background technology]
As everyone knows, alloy materials such as aluminium, titanium are because of having advantages such as intensity height, light weight, and are widely used in fields such as aviation, electronics, communication.In order further to improve its surface quality and visual effect, industry adopts painted usually or anode processing technique is reached.As United States Patent (USP) the 5th, 215, disclosed a kind of trailing of titanium base object No. 606, before to the object spraying, at first under vacuum, add hot basal body, its surface microstructure is grown up, carry out anodizing then, and by changing the two poles of the earth voltage control surface oxide layer color.For another example, 1155019A number disclosed a kind of titanium of Chinese patent CN surface coats the novel process of composite armor, and the mode that this process using anodic oxidation combines with heated oxide is to improve the stability of surface oxide layer.
But the oxide thickness homogeneous that aforesaid method obtained lacks the convexo-concave stereoscopic sensation.In addition, it is difficult to obtain the pattern of multicolour, many lines texture on same metallic matrix, so that the surface color and polish dullness, lacks aesthetic feeling.
[summary of the invention]
The object of the present invention is to provide a kind of formation to have the method for multicolour, many lines texture or stereo pattern at metal base surface.
The object of the present invention is achieved like this: to the metal base surface anodizing time, according to following steps: (1) anodizing forms oxide film at metal base surface; (2) partial oxide film is removed in laser sculpture or etching; (3) carrying out secondary anode handles; (4) repeating step (2) and (3).
Compared with prior art, the invention has the advantages that: can obtain to have multicolour, many lines texture or relief pattern at metal base surface as required.
[embodiment]
