Abstract

The invention provides a surface palladium-free environment-friendly low-cost activated electroplating process. The process comprises the following steps of S1 pretreatment; S2 degumming; S3 copper replacement; S4 acid copper plating; S5 chromium plating; and S6 drying. The electroplating process is good in degreasing and activating effects, short in copper-plating and chromium-plating time, stable in copper-plating and chromium-plating effects, high in electroplating efficiency, simple and convenient to operate, stable in process performance, low in electroplating cost, good in economic benefit, nontoxic and environment-friendly in raw materials used in the electroplating process and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of electroplating, and in particular relates to a surface palladium-free, environment-friendly and low-cost activation electroplating process and a grinding process thereof. Background technique [0002] Electroplating is the process of plating a thin layer of other metals or alloys on the surface of certain metals using the principle of electrolysis. It is a process of using electrolysis to attach a layer of metal film to the surface of metal or other material parts to prevent metal oxidation ( Such as rust), improve wear resistance, electrical conductivity, reflective properties, corrosion resistance (copper sulfate, etc.) and enhance the appearance. 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...
