The surface treatment technology currently used can be divided into many types according to the method used. What is the electrochemical method? Take a look at the simple analysis below.

Electrochemical method is to use electrode reaction to form a coating on the surface of workpiece. So, how does it work?

Oxidation

In the electrolyte solution, the workpiece is the anode, and the process of forming an oxide film on the surface under the action of external current is called anodic oxidation, such as the anodic oxidation of aluminum alloy.

Plating

In the electrolyte solution, the workpiece is the cathode. The process of forming a coating on the surface under the action of an external current is called electroplating. The coating can be metal, alloy, semiconductor or contain various solid particles.

Actually? Commonly used steel can be treated by oxidation and electrochemical methods. The chemical method is to put the workpiece into an oxidizing solution, and rely on chemical action to form an oxide film on the surface of the workpiece, such as the bluing treatment of steel.

The above is the electrochemical method in surface treatment technology. The manufacturer reminds that more details are available in Zhibang Technology.
