Problems solved by technology

[0004] Due to the improper surface treatment of the substrate during electroplating, there are certain holes on the surface, which leads to uneven coating formed by electroplating, and even leads to certain pores in the formed coating, which affects the overall strength of the formed coating. At the same time, due to its overall The strength is low. In a high-heat environment, there is a large space for the expansion of the coating inside the coating, which causes the thermal stress of the coating to change easily. The corrosion resistance of the coating is greatly reduced, affecting its protection of the substrate

Abstract

The invention discloses a fast-charging corrosion-resistant coating, which belongs to the field of electroplating. A fast-charging corrosion-resistant coating has the effect of two opposite and misaligned dislocation undulating stays inside the coating through the setting of a reinforcing interlayer in the coating. On the one hand, the impact resistance of the coating is improved, and on the other hand, the overall strength of the coating is effectively improved. At the same time, with the stability of the umbrella point and the reinforcement of the umbrella point, the new lightweight air condensation in the fulcrum layer of the umbrella surface Colloidal particles can fall and infiltrate into the outer coating along the end of the main carbon fiber tube and fill the gaps in it, so as to make up for the low density and gaps caused by the pores on the surface of the substrate, thereby effectively improving the strength of the outer coating. At the same time, it can effectively improve the thermal stress stability of the coating, reduce the occurrence of falling off when it is hit, effectively avoid the occurrence of local falling off, and then significantly improve its corrosion resistance.

Description

technical field [0001] The invention relates to the field of electroplating, in particular to a fast-charging corrosion-resistant coating. Background technique [0002] Electroplating is to use electrolysis Principle The process of coating some metal surfaces with a thin layer of other metals or alloys, using electrolysis The process of attaching a layer of metal film to the surface of metal or other material parts to prevent metal oxidation (such as rust), improve wear resistance, Conductivity , reflectivity, corrosion resistance (copper sulfate, etc.) and aesthetic enhancement. The outer layer of many coins is also electroplated. [0003] During electroplating, the plated metal or other insoluble materials are used as the anode, and the workpiece to be plated is used as the cathode, and the cations of the plated metal are reduced on the surface of the workpiece to be plated to form a coating. In order to eliminate the interference of other cations and make the coating...
