What Is Aluminum Surface Treatment Process
Dec 05, 2016

Aluminum surface treatment is divided into: fluorocarbon coating, powder coating, anodizing (cathodic oxidation), electrophoresis, electroplating and so on.

 These aluminum surface treatment methods are simular but different, the common point is that the aluminum surface is added a layer of protective film; the difference is fluorocarbon coating, powder coating is by electrostatic film surface treatment in the aluminum, it is also known as electrostatic spraying. Anodic oxidation, electrophoresis is through the positive and negative DC and the formation of the membrane molecules, atoms and ions of positive and negative absorption of mobile adhesion to the metal surface and the formation of the protective film;

 Electroplating and anodizing, electrophoretic process have similarities, the difference is: can not be plated metal, plating solution containing a metal coating (zinc, chromium, nickel, etc.) compounds, conductive salts, buffers, 

PH adjusters and additives such as aqueous solution composition:

1, plating can be on the metal and plastic processing.

2, electrophoresis and anodizing can only be carried out on the conductive objects.

3, electroplating and electrophoresis are  used to treat material surface, in other words, is the thickness increase.

4, while the thickness of the aluminium profile will be reduced after the object treated by the anodizing.

In short: aluminum surface treatment have to follow the customer's requirements.
