In the machining process of mechanical equipment parts, the surface treatment processes of metal aluminum parts often include black anode, sand blasting oxidation, wire drawing oxidation, natural color anode oxidation and hard white oxidation. These treatments are to make the parts achieve the corresponding effect. Let’s take a look at the principle of natural color anodizing in the surface treatment of mechanical parts
The meaning of Natural Color Anodizing of aluminum for mechanical parts is: the color of aluminum after electrolysis after alkali corrosion. In fact, the thickness of aluminum film determines the color. Generally, the electrolysis time is 10 minutes, the voltage is 12F and the temperature is 24D. It is found that the composition of aluminum material changes, and the oxidized film should be between 10mu-15mu. This treatment is called natural color anodizing of aluminum. The function of Natural Color Anodizing not only increases the hardness of the part surface, prolongs the service life of the part, but also improves the appearance of the part.
The above is the sharing of the principle of natural color anodizing in the surface treatment of mechanical parts. Thank you for your attention!
