DJ triangle lighting truss is made of high-strength aluminum alloy material 6061-T6, or 6082-T6, because aluminum itself is a more active metal component, it is easy to chemically react with the external acid and alkali, if it is long-term In the water, the aluminum component will also react chemically in the water. In order to improve the stability of the performance of the DJ triangle lighting truss, the acid and alkali resistance is improved, and the DJ triangular lighting truss is oxidized to make the surface attached. An oxide film prevents the corrosive effect of foreign substances on the aluminum alloy truss.
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 ring metal oxide film used in aluminum alloy to change the surface state and performance, such as surface coloring and improve resistance. Corrosive, enhanced wear resistance and hardness, protection of metal surfaces, etc.
For example, aluminum is anodized, and an aluminum alloy is placed in the corresponding electrolyte 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, the thickness of which is 5-20 micrometers, and the anodized aluminum or its alloy improves the hardness and wear resistance of the DJ triangular illumination truss.
