Abstract
The invention discloses a method for generating microarc and colorful anode on light metal or light metal alloy, and the method comprises the following steps: A. on the surface of the light metal or light metal alloy, printing or spraying an anti-microarc-oxidation substance according to a designed figure or pattern; B. putting a product into a microarc oxidation tank, and generating a ceramic membrane in the tank; C. taking out the product generating the ceramic membrane, and removing the anti-microarc oxidation substance; D. putting the product into an anode oxidation tank, and generating an oxidation membrane in the tank; and E. taking out the product. By utilizing the method, the microarc oxidation ceramic membrane and the anode oxidation membrane can simultaneously exist on the surface of the product of the light metal or light metal alloy, so that the product simultaneously reaches various appearance levels and has improved appearance texture; and in the oxidation membrane forming process, dye is used for colouring to bring vivid color for the oxidation membrane and increase beauty. Meanwhile, the ceramic membrane and the oxidation membrane both have hardness and abrasive resistance, and the abrasive resistance of the product is guaranteed.
Description
Technical field
The present invention relates to the surface treatment method of a kind of metallic surface treatment process, particularly light metal or light metal alloy.
Background technology
Before light metal or light metal alloy product carried out practical application, all can carry out surface treatment to form compact film usually at product surface.Such rete has good hardness and antiwear characteristic, can protect the ground of product not corroded, but also makes product surface that good insulating property be arranged.
Light metal or light metal alloy product are carried out the technology that surface treatment uses differential arc oxidization technique is arranged, it places aqueous electrolyte liquid with light metal or light metal alloy product, utilize electrochemical process to produce the spark discharge spot on the surface of product, in the thermochemistry effect, under the acting in conjunction of plasma chemistry effect and electrochemical action, the surface of product forms the metal oxide ceramic film.But this ceramic membrane sense of touch is drier and more astringent, and the gloomy dullness of color.
The technology of the surface of light metal or light metal alloy product being handled use also has anodizing technology, this technology is the electrochemical oxidation to light metal or light metal alloy, its with the product of light metal or light metal alloy as anode, adopt electrolytic method, under the effect of specified conditions and impressed current, carry out electrolysis, thereby make product surface form sull.According to the difference of light metal or light metal alloy material and the difference of oxidation treatment method, sull can present the comparison unique color, and outward appearances such as texture characterize, and is single but this sull outward appearance characterizes, and do not have the level aesthetic feeling.
Summary of the invention
The technical problem to be solved in the present invention is, the outward appearance that overcomes the light metal of prior art or the rete that the surface of light metal alloy treatment process forms does not have the defective of aesthetic feeling, a kind of differential of the arc and colored anodic method of generating on light metal or light metal alloy is provided, this method can provide on the surface of light metal or light metal alloy in the different appearance tactile impression and aesthetic feeling, can also guarantee the wear resistance of product.
In order to achieve the above object, the technical solution used in the present invention is:
On light metal or light metal alloy, generate the differential of the arc and colored anodic method, it is characterized in that comprising following steps:
A. at light metal or light metal alloy product surface according to the figure or the pattern printing of design or spray anti-differential arc oxidation material;
B. product is placed the differential arc oxidation groove, in groove, generate ceramic membrane;
C. take out the product that generates ceramic membrane, remove anti-differential arc oxidation material;
D. product is placed anodizing tank, in groove, generate oxide film;
E. take out product.
As a kind of optimal way,, be added with stain in the anodizing tank at step D.
Adopt technique scheme, the present invention has reached following beneficial effect with respect to prior art:
Use this method that ceramic membrane and oxide film are present on the product surface of light metal or light metal alloy simultaneously, make product reach two kinds of texture simultaneously; Oxide film can also bring the color of the outward appearance of product with uniqueness; Can also in the film formed process of oxidation, give paintedly, can bring bright colour, increase aesthetic feeling to oxide film with stain.Meanwhile, ceramic membrane and oxide film are all had hardness and a wear resistance, can guarantee the wear resisting property of product.
Description of drawings
Fig. 1 is the present invention generates the preferred implementation of the differential of the arc and colored anodic method on light metal or light metal alloy a schematic flow sheet.
Embodiment
The present invention is described further below in conjunction with accompanying drawing and preferred implementation.
What Fig. 1 showed is the present invention generates the preferred implementation of the differential of the arc and colored anodic method on light metal or light metal alloy schematic flow sheet.As shown in the figure, the method for present embodiment comprises following steps:
A. at light metal or light metal alloy product surface according to the figure or the pattern printing of design or spray anti-differential arc oxidation material;
B. product is placed the differential arc oxidation groove, in groove, generate ceramic membrane;
C. take out the product that generates ceramic membrane, remove anti-differential arc oxidation material; This moment is promptly exposed outside by the product surface that anti-differential arc oxidation material is covered with originally;
D. product is placed anodizing tank, in groove, generate oxide film; At this moment, the oxidized formation oxide film of exposed product surface, ceramic membrane then can not be subjected to anodised influence;
E. take out product.
The external appearance characteristic of ceramic membrane is a mist, and sense of touch is dry and astringent, and color is gloomy, dull; The external appearance characteristic of oxide film is according to the difference of the difference of light metal or light metal alloy material and anode oxidation method and difference, and for example the product to aluminium alloy carries out anodic oxidation: the oxide film through sulphuric acid anodizing is colourless; Through the oxide film of oxalic acid anodizing according to adopting electric current kind difference, the thicknesses of layers difference, the surface is yellow-green colour to Vandyke brown; Through the general gray of oxide film of chromic acid anodizing to grey black.
Thereby the appearance tactile impression of ceramic membrane and oxide film is different, and the coexistence of the two can increase the appearance tactile impression and the outward appearance level of product surface.
Simultaneously, in anode oxidation process, add colored stain in anodizing tank, stain can be deposited in the oxide film, can be so that oxide film presents bright colour.
With embodiment the present invention has been done detailed explanation in conjunction with the accompanying drawings above, but the present invention is not limited to this, any those skilled in the art under the prerequisite of aim of the present invention, can make various distortion and modification in the ken that is possessed.
