How to improve the stability of Aluminum Triangle Bolt Truss

Mar 13, 2019

The Aluminum Triangle Bolt Truss is made of high-strength aluminum alloy material 6061-T6 or 6082-T6. Because aluminum itself is a relatively active metal component, it is easy to chemically react with the external acid and alkali. In the water, the aluminum component also reacts chemically in the water.


In order to provide the stability of the performance of the aluminum triangular bolt truss, the acid and alkali resistance of the aluminum triangular bolt truss is improved, and the aluminum triangular bolt truss is oxidized to provide an oxide film on the surface, which prevents the external matter from adhering to the aluminum alloy truss. Corrosion. In order to overcome the defects of surface hardness and wear resistance of aluminum alloy and prolong the service life, surface treatment technology has become an indispensable part of the use of aluminum alloy.


Metal oxide films alter surface conditions and properties such as surface coloration, improved corrosion resistance, enhanced wear resistance and hardness, and protection of metal surfaces. For example, aluminum is anodized, and the aluminum alloy is placed in a corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as an anode, and electrolysis is performed under specific conditions and an applied current. The aluminum of the anode or its alloy is oxidized, and a thin layer of aluminum oxide is formed on the surface thereof, and the thickness thereof is 5 to 20 μm. The anodized aluminum or its alloy improves the hardness and wear resistance.
