Is Black Anodizing The Same As Blackening?
Nov 04, 2022
It's not the same.
Anodic oxidation is the electrochemical oxidation of metals or alloys. 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.
Blackening is a common means of chemical surface treatment. The principle is to produce a layer of oxide film on the metal surface to isolate the air and achieve the purpose of rust prevention. When the appearance requirements are not high, blackening can be used. The surface of steel blackening is also called blue.
