Aluminium alloy anodic treatment
Nov 25, 2022
1, aluminum alloy anodic treatment refers to anodic alumina, is in aluminum and aluminum alloy surface plating a layer of dense alumina, in order to prevent its further oxidation. The principle is the anode effect: refers to the current transmission between the anode and the electrolyte is inhibited resulting in blocking phenomenon.
2, anodic alumina production process
(1) Mechanical polishing;
(2) Chemical treatment to remove the copper composition on the surface of some alloys;
(3) clean and remove oil;
(4) Put in dilute sulfuric acid as an anode for electrification, generating surface oxide layer;
(5) dyeing;
(6) Fixed.
