How To Improve The Acid And Alkali Resistance Of Aluminum Alloy Truss?
- Aug 30, 2017 -

Because aluminum alloy truss is the use of high-strength aluminum alloy material T6, or 6082-t6 to weld, because aluminum itself is more active metal components, it is easy to react with the outside world of acid-base reaction, if it is in the water, aluminum composition will also occur in the water chemical reaction, In order to provide the stability of the aluminum alloy truss performance, the Yao Na stage technician has carried on the enhancement to the acid and alkali ability to him, the aluminum alloy truss carries on the oxidation treatment, causes its surface to attach a layer of oxide membrane, prevented the outside material to the aluminum alloy truss corrosion effect.

In order to overcome the defects of aluminum alloy surface hardness, abrasion resistance and other aspects, prolong the service life, surface treatment technology becomes an indispensable part in the use of aluminum alloy. Metal oxide films change the surface state and properties, such as surface coloring, enhance corrosion resistance, enhance wear resistance and hardness, protect metal surface and so on. For example, aluminum anode oxidation, aluminum alloy in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as the anode, in the specific conditions and the effect of the external current, electrolysis. Anodized aluminum or its alloy oxidation, surface formation of alumina thin layer, its thickness is $number micron, anodized aluminum or its alloy, improve its hardness and wear resistance.
