Why do aluminum parts need oxidation surface treatment after machining

1. Aluminum alloy is a very corrosion-resistant raw material. The machined surface of aluminum alloy parts will produce oxygen oxidation when it encounters oxygen, which will gradually eliminate its corrosion resistance and gluten resistance after a long time. Aluminum alloy parts machining is especially sensitive to acid. When it encounters acid, it will damage the surface layer of aluminum alloy. Need to oxidize again, add another layer on the surface to improve the surface corrosion resistance protective film.

2. After the surface of aluminum alloy parts is machined by anodic oxidation treatment, the corrosion resistance, hardness standard, wear resistance, insulation performance, and high-temperature resistance have been greatly improved. Anodized aluminum alloy film surface porous structure is easy to adsorb dyes and colored substances, and can be colored to improve its ornamental value. The oxide film is treated with boiling water, high-temperature steam, or nickel salt to further improve its corrosion resistance and wear resistance.

Anodic oxidation treatment technology is widely used in parts machining metal surface treatment

1. Avoid corrosion of aluminum alloy parts

The film obtained by anodic oxidation treatment is reasonably closed and has very good stability in the atmospheric environment. Whether the oxide film is obtained from the sulfuric acid solution, oxalic acid solution, or chromic acid solution with normal processing, its corrosion resistance is very good, such as aluminum pots and pans, pots and pans, washing machine liners, etc. The chromic acid oxidation method is especially suitable for aluminum welded parts and riveted parts.

2. Protection of parts machined parts decorative design effect

On the oxide film with high transparency, the oxide film can absorb a variety of organic dyes or inorganic pigments. On the oxide film, you can get a variety of bright and colorful color combinations and pattern designs. Such as multiple coloring by one oxidation, wood grain pattern design, oxidation offset printing, porcelain oxidation, etc., which makes the appearance design of aluminum alloy parts more individual. Beautiful and pleasing to the eye, this color film is the decorative design layer and also the anti-corrosion layer, such as lighters, gold pens, and various crafts.

3、It can add a hard wear-resistant layer for aluminum alloy parts machining

In sulfuric acid or oxalic acid solution, a thick and hard film layer can be obtained according to the processing standard of adjusting anodic oxidation treatment. The pores and adsorption characteristics of the film can be used to store selective oil, which can be reasonably effective as a standard for operation in a frictional environment. It also has the characteristics of lubrication and wears resistance, such as automobile engine cylinders and piston rods of cars and agricultural vehicles. High-quality appearance parts aluminum alloy parts machining, aluminum alloy CNC anodizing, powder spraying, lightning carving, and other different surface treatment methods, with professional production and processing equipment and high-precision testing instruments, high quality and high speed to complete the order.

Aluminum medical machinery parts hard anodized colors:

Hard anodized surface color, usually done with the original color and black; hard anodized original color, the actual from gray - dark gray-brown/taupe - brown are different, the substrate will lead to different colors of the hard anodized film; In addition, with the increase in film thickness, the color of the film layer will also become darker.
