Abstract
Official abstract text for this publication.
There is provided a metal member capable of effectively preventing a coating layer from peeling off from a base. The metal member in an embodiment is a metal member that is used in a solid-oxide type electrochemical stack, and includes: a base formed of ferritic stainless steel; and a metal film provided on the base, in which the metal film includes a first metal layer containing Co and a second metal layer made of Mn, and is a stack in which the first metal layer and the second metal layer are sequentially stacked from the side of the base.
First claim
Opening claim text (preview).
What is claimed is: 1. A manufacturing method of a metal member being a manufacturing method of a metal member for being used in a solid-oxide type electrochemical stack, the metal member comprising: (a) a base formed of ferritic stainless steel; and (b) a metal film provided on the base, wherein the metal film includes a first metal layer containing Co and a second metal layer made of Mn, and is a stack in which the first metal layer and the second metal layer are sequentially stacked from a side of the base, the manufacturing method comprising: heating the metal film provided on the base to form a composite oxide, wherein an element ratio of an amount of the first metal layer to an amount of the second metal layer is from 8:2 to 7:3 in density such that the metal film is prevented from peeling off from the base.
