The invention is relative to an electrode for gas evolution in electrolytic and electrometallurgical industrial applications, made of a metal substrate having a surface morphology characterised by a combination of micro-roughness and macro-roughness which favours high adherence of a superficial catalytic layer in order to prevent detachment of the same and passivation of the substrate even under critical operating conditions.
L'invention a trait à une électrode destinée au dégagement gazeux dans des applications industrielles liées à l'électrolyse et à l'électrométallurgie. Ladite électrode a une morphologie superficielle caractérisée par une combinaison de qualités telles que la microrugosité et la macrorugosité, lesquelles favorisent une forte adhérence de la couche catalytique visant précisément à en prévenir le décollement, et par la passivation du substrat et ce, même dans des conditions d'exploitation critiques.
