Abstract
A composite member includes a base member and a covering layer. The base member includes a first surface not exposed to an oxidizing atmosphere and contains chromium. The covering layer covers the first surface and includes a first outer surface that is not exposed to the oxidizing atmosphere. At least one of the base member and the covering layer includes an exposed surface that is exposed to the oxidizing atmosphere. The surface roughness of the exposed surface is different from the surface roughness of the first surface or the first outer surface.
Claims15
A member comprising:
- a base member comprising a first surface not exposed to an oxidizing atmosphere and a second surface exposed to the oxidizing atmosphere and being in contact with the first surface, the base member containing chromium;
- and
- a surface roughness of the second surface is smaller than a surface roughness of the first surface.
A composite member comprising:
- a base member;
- a covering layer configured to cover the base member;
- and
- one or a plurality of particle bodies positioned in an inner region, and not positioned in an outer region and in the base member, and
- wherein the covering layer comprises:
- an inner surface facing the base member;
- an intermediate portion positioned at a center between an outer surface of the covering layer and the inner surface;
- the inner region extending from the intermediate portion to the inner surface;
- and
- the outer region extending from the outer surface to the intermediate portion.
