The electrolyte used in the anodizing of aluminum and its alloys is generally an acidic solution with medium solubility, and lead as the cathode only plays a conductive role. When anodizing aluminum and its alloys, the following reactions occur at the anod...

Oxidation of aluminum alloy is a common surface treatment method for aluminum alloy products. Among many processing methods, oxidation is a way to save time and effort and cost.  

The requirements for the oxidized surface effect of aluminum alloy mainly involve a number of aspects to ensure that the treated aluminum alloy surface is both beautiful and has the required functionality. 

Anodizing of aluminum alloy is a common surface treatment process, which forms a dense alumina film on the surface of aluminum alloy by electrolytic oxidation to improve its corrosion resistance, wear resistance and aesthetics. However, in the process of anodi...

The matters needing attention during the anodizing process of aluminum profiles are as follows: First, control the temperature and concentration of the oxidation liquid: the temperature and concentration of the oxidation liquid directly affect the thickness a...

Aluminum or aluminum alloy products as the anode, placed in the electrolyte solution for power treatment, the use of electrolytic effect to form aluminum oxide film on the surface of the process, known as aluminum and aluminum alloy anodizing treatment.

In industrial production and processing, aluminum alloy after a long time storage, the surface will appear black, mold and other oxidation corrosion phenomenon, will affect the quality of the product, appearance, price. Aluminum alloy surface appears black, mildew phenomenon, how should be cleaned?

One, can not dye color

1.Insufficient anodic oxidation film thickness. The solution is to check whether the anodic oxidation process is standardized, to see whether the temperature, voltage, conductivity and other factors are stable, if there is an anomaly, please adjust the specification accordingly, if there is no anomaly, the oxidation time can be appropriately extended to ensure that the film thickness is up to standard.

With the development of modern industry, light metal materials are used more and more widely. Aluminum and aluminum alloy have a series of advantages such as low density, strong electrical and thermal conductivity, excellent mechanical properties, good machinability, etc., and have been widely used in various sectors of the national economy.

The surface oxidation of aluminum and aluminum alloys is the most important surface treatment process in the processing of aluminum products.
