Abstract

Solution pour le dépôt électrolytique de chrome ou d'alliages de chrome dans laquelle la source de chrome est une solution aqueuse équilibrée d'un complexe de thiocyanate de chrome et un matériau tampon qui fournit un des liants du complue. Application au revêtement de disques magnétiques, objets métalliques, décoratifs, etc.A solution for the electroplating of chromium or chromium alloys in which the source of chromium is a balanced aqueous solution of a complex of chromium thiocyanate and a buffer material which provides one of the binders of the complue. Application to the coating of magnetic disks, metal objects, decorative, etc.
