Title (EN) ELECTRODEPOSITION OF CHROMIUM AND CHROMIUM BEARING ALLOYS
(FR) ELECTRODEPOSITION DE CHROME ET D'ALLIAGES A BASE DE CHROME
Abstract:
(EN) A coating on a substrate e.g., mild steel providing high corrosion resistance consists of a first coating of nickel on which is electrodeposited an alloy consisting of 51 to 75% chromium, 5 to 15% nickel and/or cobalt and balance iron.
(FR) Un revêtement sur un substrat, par exemple de l'acier doux, permettant d'obtenir une résistance élevée à la corrosion, se compose d'une première couche de nickel sur laquelle est déposé par galvanostégie un alliage formé de 51 à 75% de chrome, 5 à 15 % de nickel et/ou cobalt, le reste étant du fer.
