Description

technical field [0001] The invention relates to the technical field of aluminum alloy processing, in particular to a wear-resistant electrophoresis aluminum alloy profile. Background technique [0002] Aluminum alloy has the characteristics of low density and high strength, and is widely used in daily life, architectural decoration and industrial fields. However, the corrosion resistance of aluminum alloy materials is poor, and intergranular corrosion is prone to occur, which limits its application range. Electrophoresis aluminum profile is a product that coats a layer of paint film on the surface of aluminum alloy profile by electrophoresis process. The corrosion resistance of profiles has many advantages compared with traditional aluminum alloy profiles. However, the electrophoretic paint film on the surface of the aluminum alloy substrate still has the problem of insufficient wear resistance, and once it is worn, it will greatly affect its corrosion resistance, thereby ...
