Abstract
On spécifie les conditions de procédé et, en particulier, les rapports entre les conditions hydrodynamiques de l'électrolyte et les densités de courant grace auxquels dans la galvanisation électrolytique, y compris celle effectuée avec une haute densité de courant, on obtient un dépot très compact et ayant une bonne résistance à la corrosion et un bon aspect superficiel. On a trouvé qu'il existe une ralation précise entre la densité de courant et les conditions hydrodynamiques de l'électrolyte, valable pour des densités de courant de valeur comprise entre les valeurs extremement basses et les valeurs très élevées.
