Abstract

Procédé de protection des surfaces de nickel noir contre les intempéries. Il consiste à effectuer un dépôt électrolytique sur ces surfaces à partir d'une solution aqueuse convenable de chromate ou de dichromate. Le dépôt transparent obtenu résiste bien aux intempéries tout en conservant au nickel noir ses propriétés de capacité d'absorption élevée et de faible émissivité.
