Abstract

L'invention concerne un procédé d'application d'une couche au noir sur une base métallique. On utilise un électrolyte formé d'un thiocyanate hydrosoluble du groupe du fer Fe, Co, Ni ou d'un mélange de ceux-ci, de manière à obtenir un coefficient d'absorption aussi grand que possible des rayons du spectre solaire et un pouvoir émissif restreint dans la gamme des rayons calorifiques jusqu'à 400 degrés K. Obtention de couches sélectives absorbantes pour capteurs solaires.
