Description

technical field

[0001] The invention relates to a method for fixed-point corrosion of the shielding at the bottom of an anodic oxidation channel by a chemical acid agent, which belongs to the field of electrochemically preparing anodic oxidation film aluminum materials without shielding layers, and is especially suitable for the application of improving the bonding force between aluminum materials and electroplated metals.

[0002] technical background

[0003] Aluminum or aluminum alloy anodizing refers to the process of immersing aluminum or aluminum alloy in a suitable electrolyte as an anode for electrification, and forming an oxide film (Al2O layer) on the surface of aluminum or aluminum alloy. The existence of this layer of oxide film can improve the corrosion resistance of aluminum alloy. At the same time, with the help of the special structure of the oxide film and the later treatment process, for example, the anodic oxide film can also be combined with surface paintin...
