The device (2, 12, 19, 22, 26) for the electrolytic surface treatment of metals, comprises a nib (4, 11) connected with the unipolar supply of electric current (7) from an external apparatus, the other pole being connected with the metal surface being treated and a device for protecting the operator from the gases and vapours generated, and the protection device consists of a member suitable for providing the area of the nib with a flow of pressurized air (3, 5, 9, 23, 27, 29, 36). Different integrated and non-integrated embodiments of the delivery member of air in the vicinity of the nib are described.
L'invention concerne un dispositif (2, 12, 19, 22, 26) de traitement de surface électrolytique des métaux, comprenant une plaquette (4, 11) de filière connectée à l'alimentation unipolaire de courant électrique (7) d'un appareil externe, l'autre pôle étant connecté à la surface de métal traitée. L'invention concerne également un dispositif destiné à protéger l'opérateur contre les gaz et vapeurs générés, et constitué d'un élément adapté pour générer autour de la zone de la plaquette de filière un flux d'air (3, 5, 9, 23, 27, 29, 36) sous pression. L'invention concerne différents modes de réalisation intégrés et non intégrés de l'élément de distribution d'air autour de la plaquette de filière.
