Description

Technical Field

[0001] The utility model relates to the technical field of electroplating cathode protection, in particular to a cathode protection structure of an electroplated automobile trim ring. Background Art

[0002] Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. It is a process that uses electrolysis to attach a layer of metal film to the surface of metal or other material parts, thereby preventing metal oxidation (such as rust), improving wear resistance, conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and enhancing aesthetics. The outer layer of many coins is also electroplated. Cathodic protection is a type of electrochemical protection technology. Its principle is to apply an external current to the surface of the corroded metal structure, and the protected structure becomes the cathode, thereby inhibiting the electron migration caused by metal corrosion and avoiding or reducing the occurrence of corrosion.

[0003] Nowadays, automobile trims need to be electroplated for their aesthetics. Traditionally, the old glue dipping method and iron wire are used to bind and fix the trims, which easily leads to inconsistent surface thickness and large state differences of the trims after electroplating.
