Abstract

Cette invention se rapporte au traitement des métaux, et concerne plus précisément un procédé de traitement par arc électrique de pièces et d'ébauches de formes et de tailles diverses, lequel procédé permet d'éliminer les couches oxydes de types divers ainsi que les scories et l'encrassement de la surface à traiter. Cette invention permet d'accroître la qualité et le rendement du nettoyage des surfaces de pièces métalliques ayant des configurations, des sections transversales et des longueurs différentes, ceci en augmentant la densité et l'uniformité de répartition des tâches cathodiques par unité de surface de la surface à traiter, ainsi que la vitesse de déplacement de ces tâches, et en augmentant également la valeur spécifique de la part de courant ionique de l'arc. Ce procédé consiste à traiter la pièce à une pression inférieure à la pression atmosphérique et en faisant se déplacer de manière contrôlée la décharge par arc et la pièce à traiter l'une par rapport à l'autre. On génère également dans le circuit de courant de travail de l'arc une composante fréquence-impulsion de la tension et du courant et/ou on utilise l'effet de quasi-anode. L'installation permettant de mettre en oeuvre ce procédé comprend, en premier lieu, une source de courant qui est équipée d'un convertisseur de tension et d'un dispositif de commande de courant. Cette installation comprend en second lieu une anode d'une structure spéciale qui assure la formation de la décharge par arc entre les pièces et la quasi-anode. Ce procédé ne nuit pas à l'environnement, et les déchets qui en résultent consistent en des oxydes de métaux qui se présentent sous forme de poudre et qui ne contiennent pas de composants chimiques agressifs. Il est également possible de combiner ce procédé de nettoyage à un processus de pulvérisation de protection sous vide.
