Abstract:
A manufacturing method for a member with a coating having molten metal corrosion resistance for use in a molten metal bath, comprising:applying, on a coating formed of oxide system ceramics formed on an outermost surface of a substrate, a sealing solution including an inorganic colloid compound solution containing an inorganic colloid having a grain diameter within a range of 5-50 nanometers in an amount of 5-50 weight percent, and an inorganic binder, said inorganic binder being mixed at a weight ratio of 0.3-3.0 with respect to a weight of 1.0 of the inorganic colloid, said oxide system ceramics formed on the outermost surface of the substrate being an oxide containing 5% or more of a composite oxide comprising (a) at least one of Al, Ti, V, Cr, Fe, Co, Rh, In and rare earths, which are trivalent metal elements, and (b) at least one rare earth different from that used in (a), andbaking the sealing solution on the coating after permeation.
