摘要

Device for anodising treatment of one of the faces of shaped products made of aluminium or one of its alloys, intended to be coated with a fluorocarbon film. This device comprises an anode consisting of the product 16 whose face to be treated is connected to the positive pole of a source of direct current and is placed facing a pierced cathode 14 which is connected to the negative pole of the same source of current and whose opening 13 is in relation with a vertical duct 12 for feeding the electrolyte 11. The invention finds its application especially in the treatment of cooking utensils such as, for example, frying pans and saucepans. <IMAGE>
