Background

Aluminum-based alloys are widely used as mainstream metallic materials in the world, and are widely applied to ships, mechanical equipment, marine engineering and harbor facilities in seawater medium, and facilities such as pipelines and cables in sea mud. The requirements of the working conditions on the metal material are severe, and the oxide film of the aluminum-based alloy plays a crucial protection role on the material, which is mainly embodied as follows: (1) the corrosion resistance is high, the aluminum oxide film is a compact and transparent protective film, the chemical property of the aluminum oxide is stable, the aluminum oxide film is very corrosion resistant, and the pure aluminum oxide film is even more corrosion resistant than the aluminum oxide film. (2) The surface porous oxide film has the capacity of adsorbing a lubricant, so that the surface of the industrial aluminum profile is more wear-resistant. (3) The anodic oxide film of the industrial aluminum profile is not a metal substance, and the aluminum oxide is non-conductive and is a good insulating material. It is especially suitable for electronic and electric equipment manufacturers. (4) The heat insulation property is that the heat conductivity coefficient of the anodic oxide film is greatly lower than that of the aluminum profile substrate, the aluminum oxide film can resist the high temperature of 1500 ℃ at most, and the aluminum profile substrate can only bear the high temperature of 660 ℃ at most. (5) The adsorption property, which is a metal in the United states, is considered that the anodic oxide film of the industrial aluminum profile is a porous structure and has strong adsorption capacity, so that various pigments, lubricants, resins and the like are filled in the pores, and the protection, insulation, wear resistance and decoration properties of the aluminum product can be further improved. In summary, the aluminum oxide film is critical to the protection of the aluminum alloy.

At present, the process of the aluminum oxide film mainly comes from an electrochemical oxidation method and an alkaline oxidation method, and in the process of forming the oxide film, the density and the uniformity of the aluminum oxide film formed on the surface of the aluminum alloy are difficult to control in the process, and an inspection means is lacked, and the density and the uniformity of the aluminum oxide film have a crucial influence on the performance of the material, so that the research and development of a detection device capable of detecting the uniformity of the aluminum oxide film have great research significance and market prospects.
