Problems solved by technology

However, in the electroplating process, the coating material is not environmentally friendly, and there is a problem of environmental pollution during the process.
Some vacuum plating technologies partially solve the emission problem to some extent, but the adhesion between the coating and the substrate is poor
[0003] Another method is to directly spray metal paint on the substrate to achieve anti-corrosion effect, but the surface hardness is low and easy to wear, once worn, it can no longer play the role of corrosion resistance

Embodiment 1

[0020] A multi-layer aluminum-chromium composite cable coating and its preparation method, characterized in that: the structure of the aluminum-chromium composite coating is: the bottom layer is an adhesive layer, the middle is an aluminum-chromium composite metal layer, and the top layer is an organic anti-corrosion layer. corrosion layer.

[0021] The composite metal layer mainly contains aluminum and chromium, and the content of aluminum and chromium is: 85-90:15-10 by mass; the coating is used for copper, ordinary carbon steel, stainless steel or hard alloy cable metal Substrate surface. The structure of each layer reaches the sub-nanometer structure, the middle aluminum-chromium composite metal layer is 0.5-0.6 μm, and the upper organic anti-corrosion layer is 0.2-0.3 μm. Among them, the bottom adhesive layer is 0.2-0.3 μm, and the aluminum content is 20-40%. Wherein the bottom adhesive layer also includes methyl ether, and its content is 10-20%. The composite metal co...

Abstract

The invention relates to a multilayer aluminum-chromium composite metal cable coating and a preparation method thereof. The coating is applied to abrasion resistance and corrosion resistance of surfaces of cable metal materials including copper, straight carbon steel, stainless steel, hard alloy and the like, adds the metallic effect and belongs to the field of metal surface treatment, metal corrosion and protection and mechanical processing. The wear-resisting corrosion-resisting aluminum-chromium composite cable coating and the preparation method thereof lead the coating to have the metallic attractive effect, and simultaneously in the machining process, the multilayer aluminum-chromium composite metal cable coating and the preparation method thereof cause no environmental pollution, reduce cost and are applicable to large-scale production.

Description

technical field [0001] The patent of the invention relates to a multi-layer aluminum-chromium composite cable coating and its treatment method. texture effect. It belongs to the field of metal surface treatment, metal corrosion and protection and mechanical processing. Background technique [0002] Traditionally, the surface treatment of the metal base material of the cable has the effect of anti-corrosion and wear resistance, which is achieved by using electroplating technology to attach one or a composite corrosion-resistant material to the surface of the base material. The electroplating technology basically uses the substrate as the anode, the material to be plated as the cathode, and applies a voltage so that the material to be plated is evenly deposited on the surface of the substrate, increasing the wear resistance and reflective properties of the substrate, and improving the appearance of the metal effect. Corrosion resistance can also be achieved to a certain exte...
