Title:
STAINLESS STEEL MEMBER HAVING HEAT-RESISTANT COVER LAYER OR COATING FILM, AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2019/163674
Kind Code:
A1
Abstract:
Provided, as a stainless steel member having chromium poisoning prevention performance, which is sufficiently suited to applications such as collector members of solid oxide fuel cells (SOFC) to be exposed to high temperatures, is a stainless steel member which uses a ferritic stainless steel sheet containing 11-40% by mass of Cr as the base material and has a laminate as a coating film that is formed on the base material, said laminate having a thickness of 0.5-50 μm. The laminate comprises a layer that contains an Co oxide in the outermost surface, while having a layer that contains CoWO4 at a position closer to the base material than the layer that contains an Co oxide.
