Electrochemical method and electrochemical device

Abstract

The invention provides an electrochemical method and an electrochemical device. The electrochemical method and the electrochemical device are applied to electrochemical processing such as electroplating and electro-polishing on the surface of a processed object; in particular when the method and the device are applied to a large-dimension processed object, no large current is needed and continuous batch completion can be realized, and the method and the device have the advantages and effects of effectively saving labor, space and time, and being excellent in processing uniformity; the electrochemical method is mainly characterized in that an electrode plate and an electrolyte are arranged in a plating tank module, the processed object is contacted with the electrolyte by virtue of relative movement generated between the plating tank module and the processed object so that an electrolytic reaction is aroused, and then electrochemical processing on the surface of the processed object is realized.

Description

technical field [0001] The present invention relates to an electrochemical method and its device, especially an electrochemical method and its device which can save power, effectively save manpower, space and time, and have good processing uniformity. Background technique [0002] Electrochemical technology is one of the most important processing technologies in the industry in recent years. Because electrochemical technology involves chemical reactions in which electrons are transferred, it has a wide range of applications. The main application of electrochemical technology is the electroplating process. [0003] The electroplating process has been widely used to repair the worn workpiece surface. For example, hard chrome plating is used for the surface treatment of hydraulic cylinders and rollers, while electroplating copper or nickel metal is often used to fill the worn area of ​​the workpiece. , In addition, silver plating is also often applied to the workpiece of circ...

AI Technical Summary

Problems solved by technology

However, the workpiece size applicable to the immersion plating method will be limited by the size of the plating tank, especially for bulky workpieces or workpieces that only need to be electroplated in a local area, it is difficult to meet the requirements

And especially when the size of the workpiece to be plated increases, the uniformity of the electroplated metal layer will be less ideal, making the thickness difference between the central area and the surrounding area larger

This phenomenon will reduce the yield rate in the electroplating process, thereby increasing the cost of the process
