The invention relates to a method for inspecting the surface quality of the deposit created on the surface of an electrode in the electrolytic treatment of metals. According to the invention, a cathode (1) obtained from electrolytic treatment is illuminated by at least one light source (3) placed in an oblique position with respect to the plane (12) that constitutes the cathode surface, and an image of the illuminated surface (12) is made with at least one camera (8); said image is then transmitted to an image processing arrangement (9), and on the basis of said image, there are defined possible irregularities of the surface in order to classify the deposit (11) located on the cathode for the next processing step.

L'invention concerne un procédé permettant de contrôler la qualité de la surface d'un dépôt qui a été formé à la surface d'une électrode dans le traitement électrolytique des métaux. Dans le mode de réalisation décrit dans l'invention, une cathode (1) obtenue à partir d'un traitement électrolytique est éclairée par au moins une source lumineuse (3) placée dans une position oblique par rapport au plan (12) que constitue la surface de la cathode. Une image de la surface (12) éclairée est produite à l'aide d'au moins une caméra (8); cette image est ensuite transmise à un dispositif (9) de traitement d'images. En fonction de cette image, d'éventuelles irrégularités de la surface sont alors définies de manière à classifier le dépôt (11) se trouvant sur la cathode pour la prochaine étape de traitement.
