Common Surface treatment Technology of hand Plate (Video +gif ) (Second)


Electroplating is the process of plating a thin layer of other metals or alloys on the surface of some metal or other materials by electrolysis. 

Anodic oxidation refers to the process of forming a layer of oxide film on aluminum products (anode) under the corresponding electrolyte and special process conditions and under the action of external current.

Electrophoretic coating is a kind of electrophoretic coating which moves to the cathode under the action of voltage, and acts with the alkaline substance produced on the surface of the cathode to form an insoluble substance, which is deposited on the surface of the workpiece. 

Micro-arc oxidation also called micro-plasma oxidation, is an instantaneous high-temperature and high-pressure effect produced by arc discharge on the surface of aluminum, magnesium, titanium and its alloys through the combination of electrolyte and corresponding electrical parameters. The ceramic film with metal oxide as the main substrate was grown. 

Metal wire brushing is a kind of surface treatment method to finish the surface of workpiece by grinding product to form the line grain on the surface of the workpiece.


Mechanical polishing is a method to obtain smooth surface by cutting plastic deformation of material surface and removing the raised part after polishing. 

Electropolishing is actually a method of polishing metal surface based on the principle of electrochemical anodic dissolution.
