Surface treatment


1. Anodizing:

Aluminum and its alloys form an oxide film on the aluminum products (anode) under the action of external current under the corresponding electrolyte and specific process conditions.

In order to overcome the defects of surface hardness and wear resistance of aluminum alloy, expand the application range and prolong the service life, surface treatment technology has become an indispensable part in the use of aluminum alloy, and the anodizing technology is the most widely used and most successful.
