How To Improve The Acid And Alkali Resistance Of Aluminum Alloy Trusses?

Because aluminum alloy trusses are welded with high-strength aluminum alloy materials 6061-T6 or 6082-T6, because aluminum itself is a more active metal component, it is prone to chemical reactions with external acids and bases. In the water, the aluminum component also undergoes a chemical reaction in the water. In order to provide stability of the performance of the aluminum alloy truss, Yaona stage technicians have improved his acid and alkali resistance and oxidized the aluminum alloy truss to make its surface An oxide film is attached to prevent the corrosive effect of foreign matter on the aluminum alloy truss. In order to overcome the defects of aluminum alloy surface hardness, wear resistance, etc. and extend the service life, surface treatment technology has become an indispensable part in the use of aluminum alloys. Metal oxide films change the surface state and properties, such as surface coloration, increase corrosion resistance, enhance wear resistance and hardness, and protect metal surfaces. For example, aluminum anodization, the aluminum alloy is placed in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as the anode, and electrolysis is performed under specific conditions and an external current. The anode's aluminum or its alloy is oxidized, and a thin layer of alumina is formed on the surface, with a thickness of 5-20 microns. The anodized aluminum or its alloy improves its hardness and wear resistance.
