Prototype model electroplating process

Electroplating refers to the metallized metal in the salty solution ,the metal as cathode,through
electrolysis effect to make the cation sedimentary out from the metal surface in the solution,form
to a coating layer it is a surface processing method.The coating performance is different from the
base metal, with new characteristics. According to the function of the coating,can be divided into
protective coating, decorative coating and other functional coatings, this process mainly through
in salt solution containing for metallized substrate metal surface deposition,forming to a coating
layer.
Electroplating process Generally including three stages :
the pretreatment before plating, electroplating, plating post-processing.
The requirements to the plating layer:
1.Should have good adhesion strength between the metal and the coating, the coating film and
 the coating film.
2.The coating should crystal,fine,smooth and uniform thickness.
3.The coating should be stipulated by the thickness and porosity of as little as possible.
4.Coating should have stipulated the indicators, such as brightness, hardness, electrical 
conductivity, etc
