Embodiment Construction

[0023] For a further understanding of the purpose of the present invention, method steps and functions, please refer to figure 1 , and detailed as follows:

[0024] In order to achieve the above object, the present invention provides a method for imitating anode treatment of aluminum alloys with high silicon content, which comprises the following steps:

[0025] Step 101: Provide an aluminum alloy product, and perform mechanical polishing and / or wire drawing on the surface of the aluminum alloy product;

[0026] Step 102: Degrease the mechanically polished and / or wire-drawn aluminum alloy product in a degreasing agent to remove surface grease;

[0027] Step 103: using a chemical polishing solution to chemically polish the degreased aluminum alloy product;

[0028] Step 104: Spray or dip-coat the surface of the chemically polished aluminum alloy product with a high-hardness nano-transparent coating.

[0029] Wherein, the high silicon content refers to that the mass percentag...

Abstract

The invention discloses a high Si-content aluminum alloy anode imitation processing method and a product thereof. The method includes the following steps: (1) providing an aluminum alloy product and carrying out mechanical polishing and / or wire drawing for the surface of the aluminum alloy product; (2) in degreasant, degreasing the aluminum alloy product after being processed through the mechanical polishing and / or the wire drawing to degrease oil on the surface of the aluminum alloy product; (3) utilizing chemical polishing liquid to carry out chemical polishing for the aluminum alloy product after being degreased; and (4) placing high-hardness nanometer transparent coating on the surface of the aluminum alloy product which is processed through the chemical polishing in a spaying coating mode or a dip coating mode. The invention further discloses the product generated through the high Si-content aluminum alloy anode imitation processing method. The high Si-content aluminum alloy anode imitation processing method and the product thereof place the high-hardness nanometer transparent coating on the surface of the aluminum alloy product which is processed through the chemical polishing in a spaying coating mode or a dip coating mode, so that the processed aluminum alloy product can maintain white metal texture. In addition, the product generated after being processed is high in wear resistance and corrosion resistance.

Description

【Technical field】 [0001] The invention relates to an imitation anode treatment method and a product thereof, in particular to an imitation anode treatment method and a product of an aluminum alloy with high silicon content. 【Background technique】 [0002] Anodic treatment is a widely used surface treatment technology. It is a surface treatment technology that has long been used in electrochemistry. Anodized treatment is generally used in: A. Increase corrosion resistance; B. Increase wear resistance; C , Improve the adhesion between the substrate and the coating; D, provide an insulating surface; E, heat dissipation; F, protect the polished and machined surface; G, improve the appearance, etc. [0003] At present, the anodic treatment seen in the market is mostly used in aluminum, aluminum alloy sheet or extruded profile products, and aluminum die-casting parts are more and more widely used recently, such as radiators, automobile fasteners and other products. [0004] Howev...
