Description

Metal substrate surface treatment method

The invention relates to a metal substrate surface treatment method, in particular to a metal substrate surface treatment method for forming different colors by a plurality of anodes and dyeing treatment.

Alloy materials such as aluminum and titanium have advantages such as high strength and light weight, and are widely used in aviation, electronics, communications and other fields. In order to further improve the surface quality and visual effect, it is usually achieved by a coloring or anodizing process. Anodizing pretreatment usually includes processes such as biting, chemical sanding, chemical polishing, etc. The post-anodizing treatment includes dyeing, sealing and other processes, making the surface treatment more complicated. In addition, the thickness of the oxide film obtained by the surface treated by the above process is uniform, and it is difficult to obtain a pattern of a plurality of colors. If you need to obtain a variety of color patterns, you can add a number of masking, dyeing, sealing and other processes, which further increases the processing flow.

In view of the above, it is necessary to provide a surface treatment method which is simple and capable of forming a plurality of color patterns on the surface of a metal substrate.

A metal substrate surface treatment method comprising the steps of: providing a metal substrate; anodizing the metal substrate and performing a sealing treatment; and correspondingly patterning the surface of the metal substrate according to a pattern formed on the metal substrate The different colors are divided into complex processing regions, and the complex processing regions are divided into a plurality of colored processing regions and an achromatic processing region according to colors, and the achromatic processing regions are black and gray corresponding processing regions, and the color processing regions are black, white, and a processing area corresponding to a color other than gray; an oxide film on a color processing region in one of the plurality of colored processing regions is peeled off by laser engraving; an anode, a corresponding color dyeing, and a sealing treatment are performed on the metal substrate to cause the peeling Forming a color oxide film having a corresponding color on the colored processing region after the oxide film; repeating the stripping of the oxide film on the color processing region and performing the dyeing and sealing process on the anode, the corresponding color, in other colored processing regions Forming a colored oxide film having a corresponding color; Color processing laser marking area, to give a gray or black pattern.

Another metal substrate surface treatment method comprises the steps of: providing a metal substrate; anodizing the metal substrate and performing a sealing treatment; and correspondingly patterning the surface of the metal substrate according to a pattern formed on the metal substrate The different colors are divided into two processing areas, the pattern includes gray and a color other than black, white, and gray, and the two processing areas include a chromatic processing area and an achromatic processing area, and the achromatic processing area is a processing area corresponding to gray in the pattern, the colored processing area being a processing area corresponding to a color other than black, white, and gray; peeling off the oxide film on the colored processing area by laser engraving; performing anode on the metal substrate Corresponding color dyeing and sealing treatment, so that a colored oxide film having a corresponding color is formed on the colored processing region; and the achromatic processing region is laser-marked to obtain a gray pattern.

The above method does not require biting, chemical polishing and chemical blasting, so there is no need to shield the metal substrate during the processing, the processing flow is reduced, the processing is simple, and the cost is reduced. The surface of the metal substrate is formed into a plurality of color patterns by performing a plurality of stripping of the oxide film and the anode, dyeing, sealing, and marking the achromatic region.

1 is a flow chart of a method for treating a metal substrate according to an embodiment of the present invention.

The metal substrate surface treatment method of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

Referring to FIG. 1, the metal substrate surface treatment method of the present invention mainly comprises the following steps:

S101: providing a metal substrate;

S102: performing anodizing treatment on the metal substrate and performing sealing treatment;

S103: dividing a different color of a corresponding pattern on a surface of the metal substrate into a plurality of processing regions according to a pattern to be formed on the metal substrate, wherein the plurality of processing regions are divided into a colored processing region and an achromatic processing region according to the color, and achromatic processing is performed. The area is a processing area corresponding to black and gray, and the color processing area is a processing area corresponding to colors other than black, white, and gray;

S104: peeling off an oxide film on one of the plurality of colored processing regions by the laser processing by laser engraving;

S105: performing an anode, a dyeing, and a sealing treatment on the metal substrate, so that a colored oxide film of a corresponding color is formed on the colored processing region after the metal substrate is stripped of the oxide film;

S106: repeating S104~S105 to form a color oxide film of a corresponding color on other colored processing regions;

S107: Perform laser marking on the achromatic processing area, and control the laser energy of the marking according to the pattern of the achromatic processing area to obtain a gray or black appearance with different tones. The laser energy is weak to strong, and the darker the gray color after marking, the laser energy reaches a certain intensity, and the black color is marked after marking;

S108: Mechanically polishing the metal substrate to improve the flatness of the metal substrate.

It can be understood that, in step S106, if the pattern of the achromatic processing area is a single color, for example, the gray of the same color, when the laser marking of the achromatic processing area is performed, the marking condition is not changed, and the achromatic processing area is performed. Gray marking of the same color can be used.

It can be understood that when the number of color processing regions is one, that is, only one color other than black, white, and gray is formed on the formed pattern, the step of S106 can be omitted.

The above method is applicable to the surface treatment of a metal substrate such as aluminum, aluminum alloy, titanium, titanium alloy, etc. In the above method, since the metal substrate has been sealed by the anode oxidizing agent, the laser engraving method is adopted when peeling off the oxide film of one of the colored processing regions. No need for biting, chemical polishing and chemical blasting, so there is no need to mask the ink on other parts of the metal substrate during processing, which reduces the processing flow, makes the process simpler, reduces the cost, and avoids the chemical caused by the ink. Pollution. By performing a stripping oxide film and a color anode on different colored processing regions in a plurality of times, color coloring processing corresponding to the colored processing region is realized. At the same time, the laser marking conditions are controlled to achieve the marking of the gradient color, and the layering of the pattern of the achromatic processing area is realized. After the pattern is formed, the surface gloss and flatness of the product are improved by mechanical polishing.

In summary, the present invention complies with the requirements of the invention patent, and submits a patent application according to law. However, the above is only a preferred embodiment of the present invention, and equivalent modifications or variations made by those skilled in the art will be included in the following claims.
