Abstract

L'invention concerne un substrat d'anode à base de métal pour cellule d'électro-obtention d'aluminium, qui comprend une partie centrale à base d'alliage de nickel ; une couche d'argent sur la partie centrale ; et une couche contenant du nickel et du fer, qui recouvre la couche d'argent et sert de couche d'ancrage pour ancrer un revêtement de surface électrochimiquement actif constituant la couche supérieure du substrat d'anode. Le revêtement de surface électrochimiquement actif peut être un revêtement à base de cérium. La couche d'argent permet d'inhiber la diffusion d'espèces fluorure dans la partie centrale et de prévenir une interdiffusion entre constituants de la partie centrale et constituants de la couche d'ancrage.
