Abstract

The invention discloses a method for forming one layer of sol-gel coating with a compact reticular crosslinking structure on the surface of the aviation aluminium alloy substrate material. The coating and an atom on the surface of the aluminium alloy substrate material can be firmly combined by the action of a chemical bond, and the coating has good adhesive force on the substrate material. In the method, graphene is added in a coating ingredient to participate in the crosslinking structure, and therefore the anti-corrosion capability of the coating is enhanced. The coating prepared by the method has strong anti-corrosion capability and adhesive force on the surface of aviation aluminium alloy. In addition, the coating has good chemical stability and thermal stability and can resist the influence on the coating because of an external acid and alkaline environment and temperature variation. The method is simple, is convenient to operate, has low requirement on equipment, is environmentally friendly and is free from pollution.

Description

technical field [0001] The invention relates to a method for treating the surface of a metal or metal alloy substrate, in particular to a method for carrying out anticorrosion treatment on the surface of aluminum and its alloy materials used in the aviation industry, and belongs to the technical field of surface treatment. Background technique [0002] Traditional surface treatment methods include anodic oxidation, chemical oxidation, electroplating and micro-arc oxidation. Among them, the chemical oxidation film prepared by the chemical oxidation method has the advantages of little influence on the fatigue properties of metal and metal alloy materials, simple process, low cost, fast formation speed, good adhesion, etc., and is often used as a primer and coating for metal and metal alloy spraying. pre-processing method. At present, the most commonly used chemical oxidation method is the chromate chemical oxidation method. After the metal and metal alloy are treated with chr...
