Description

technical field

[0001] The invention relates to a composite material with high binding force, which belongs to the field of anodized aluminum material without shielding layer prepared by electrochemical method, and is especially suitable for improving the binding force between aluminum material and electroplated metal.

[0002] technical background

[0003] With the rapid development of science and technology and industry, people have more and more stringent requirements on metal properties. Lightweight and high-hardness metal alloy materials are widely used in related fields. Since the output of aluminum in the world is second only to iron, light metal aluminum alloys The material gets a lot of attention. Aluminum and aluminum alloy materials have low hardness, poor wear resistance, and are prone to intergranular corrosion, and a thin oxide film is easy to form on the surface of aluminum under natural conditions, and the film is easy to be damaged, especially under acid (alk...
