Abstract (en)
[origin: WO2022117935A1] A process (100) for protecting a part comprising an aluminum-based alloy, the process comprising depositing (102) a primer paint layer by anaphoresis over the entire part, polymerizing (104) the primer paint layer in order to form a non-conductive polymerized primer paint layer, laser pickling (106), by means of a laser beam, an area of the non-conductive polymerized primer paint layer in order to form an unpainted area, trivalent chromium chemical conversion (108) of the unpainted area in order to form a conductive protective layer and drying (110) the part, depositing (112) a finishing paint layer on at least a portion of the non-conductive polymerized primer paint layer, and polymerizing (114) the finishing paint layer.
