Abstract

Procédé par lequel un abrasif granulaire, en combinaison avec un métal déposé, est déposé sur un métal de base pour obtenir une électrodéposition sur un outil par dépôt électrolytique. Une chambre de cathode (4) est formée dans un réservoir électrolytique (1) de sorte qu'une partie de la chambre de cathode (4) fait saillie au delà de la surface de l'anolyte (Sa). Une couche d'abrasif granulaire (8) est formée sur le fond de la chambre de cathode (4). Une partie de l'anolyte dans une chambre d'anode (7) est versée dans la chambre de cathode (4) depuis son côté supérieur de sorte qu'une différence de tête (Sc-Sa) est formée entre la surface du catholyte (Sc) et la surface de l'anolyte (sa), créant des conditions de placage telles que le pH du catholyte et la concentration du métal sont régulés de sorte que l'abrasif granulaire (8) est déposé sur un métal de base (3) sans diffuser la couche abrasive granulaire (8). Ce procédé est utilisé avantageusement pour fabriquer un outil plaqué par électrodéposition, et permet de déposer un abrasif granulaire, tel qu'une poudre de diamants, du nitrure de bore cubique ou une fine céramique, sur une base métallique, avec un métal, tel que du nickel ou du cuivre, pour produire différents outils de meulage, polissage ou coupe.
