What is anodizing aluminum alloy?
Nov 26, 2022
The anodizing of aluminum is an electrolytic oxidation process in which the surface of aluminum and aluminum alloys is usually transformed into an oxide film, which has protective, decorative and some other functional properties. From this definition, the anodizing of aluminum only includes the formation of anodizing film part of the process.
anodic oxidation, the electrochemical oxidation of a metal or alloy. Aluminum and its alloys form an oxide film on aluminum products (anodes) under the action of external current under the corresponding electrolyte and specific technological conditions. Anodizing, if not specified, usually refers to the anodizing of sulfuric acid.
In order to overcome the defects of aluminum alloy surface hardness and wear resistance, expand the application range and prolong the service life, surface treatment technology has become an indispensable link in the use of aluminum alloy, and anodic oxidation technology is the most widely used and the most successful.
