Embodiment Construction

[0019] According to the surface pattern or text coloring method of the aluminum alloy material of the present invention, such as image 3 and Figure 4 As shown, the steps are as follows:

[0020] a. First, an aluminum alloy material 10 to be colored is subjected to insulation treatment, that is, the aluminum alloy material is insulated into a non-conductor, that is, an insulator by means of electro-deposition coating. Of course, at this time, the aluminum alloy material 10 will be Because of its surface forming an insulating layer 20 to change the primary color of the aluminum alloy material such as Figure 4 a with Figure 4 the changes shown in b;

[0021] b. Use laser engraving technology to engrave text or patterns 30 on predetermined parts of the surface of the aluminum alloy material 10, such as Figure 4 A, B, C and other characters shown in c, or such as Figure 5 The whale pattern 40, such as Figure 6 There are three descriptive characters 50, and the characte...

Abstract

The invention relates to a method for coloring surface pattern or character of aluminum alloy material and products thereof. The method comprises the following steps: a surface of the aluminum alloy material is provided with an insulating layer and the pattern or character is carved by laser to become a status of local insulation and local conduction ; then by using a way of electrical coating, the conductive part of the pattern or character is sequentially processed by electrical draping to enable the pattern or character to have a draping layer different with the color of the aluminum alloy material and represent different colors as well as keeping a flat surface.

Description

technical field [0001] The present invention relates to a coloring method, in particular, to a method for coloring patterns or characters on the surface of an aluminum alloy material and its products, more specifically, to a method of engraving patterns or characters by laser, and changing the patterns or characters It is in a state of partial insulation and partial conductivity, so that the conductive part of the pattern or text can be treated with electro-deposition coating to make it appear different from the color of the aluminum alloy material. Background technique [0002] Bicycle parts known in the prior art, automobile rims, optical equipment parts, and aerospace industry parts require light weight, high-strength workpieces, mostly made of aluminum, magnesium or titanium alloys; and in order to make the workpiece wear-resistant, Corrosion resistance and high voltage resistance, it is often used to anodize the workpiece to form an oxide film on the surface of the work...
