Beschreibung
Zusammenfassung:	The invention relates to a component (8) comprising a substrate made of chromia-former metal alloy (82), the basic element of which is iron (Fe) or nickel (Ni), wherein the substrate has two main planar faces. According to the invention: - one of the main planar faces is coated with a coating comprising a thick layer of ceramic (80), grooved to delimit channels (800) suitable for the distribution and/or collection of gases, such as H2O water vapour, H2 or air, and/or - one of the main planar faces is coated with a thick metal layer (81), grooved to delimit channels (810) suitable for the distribution and/or collection of gases, such as H2O water vapour, H2, O2 or draining gas. The invention also relates to the associated production processes. L'invention concerne un composant (8) comportant un substrat en alliage métallique (82), de type chromino-formeur, dont l'élément de base est du Fer (Fe) ou du Nickel (Ni), le substrat ayant deux faces planes principales,: Selon l'invention: -une des faces planes principales est revêtue d'un revêtement comportant une couche épaisse en céramique (80), rainurée en délimitant des canaux (800) adaptés pour la distribution et/ou la collecte de gaz, tels que vapeur d'eau H2O, H2, Air et/ou -une des faces planes principales est revêtue d'une couche épaisse métallique (81), rainurée en délimitant des canaux (810) adaptés pour la distribution et/ou la collecte de gaz, tels que vapeur d'eau H2O, H2; O2, gaz drainant. L'invention concerne également les procédés de réalisation associés.
