Because aluminum alloy truss is of high strength aluminum alloy material is 6061 - T6, or is 6082 - T6 to welded together, because the aluminum itself is one of active metal component, it is easy to acid-base reaction from outside, if it is in the water for a long time, aluminum components will react in water, in order to provide the stability of aluminum alloy truss performance, yao, stage technician for the ability of the resistance to acid and alkali, to oxidation treatment of aluminum alloy truss, make its surface with a layer of oxide film, to prevent foreign materials effect on corrosion of aluminum alloy truss. In order to overcome the aluminum alloy surface hardness and wear resistance of defects, prolong service life, surface treatment technology to become an indispensable part in the aluminum alloy used. Metal oxide film has changed the surface state and performance, such as surface shading, improve the corrosion resistance and enhance the wear resistance and hardness, protect the metal surface and so on. Aluminum anodic oxidation, for example, the aluminum alloy in corresponding electrolyte ( Such as sulfuric acid, chromic acid, oxalic acid, etc. ) As anode, in certain conditions and that under the influence of impressed current electrolysis. Anode aluminum or its alloy oxide, alumina thin layer is formed on the surface, the thickness is 5 ~ 20 microns, anodic oxidation of aluminum or its alloy and improve its hardness and wear resistance.
