摘要
An object of the present invention is to provide a member for a molten metal bath provided with a composite sprayed coating having excellent corrosion resistance and peeling resistance against a molten metal. A cermet sprayed coating lower layer comprising 5-60% by weight of a metal boride and 5-30% by weight of at least one member selected from the group consisting of Co, Cr, Mo, and W with the balance comprising a metal carbide and unavoidable impurities is formed on a surface of a member for a molten metal bath such as a roll in a bath, and an oxide ceramic sprayed coating surface layer comprising combined various oxides is formed on the cermet coating, and then the obtained composite coating is subjected to sealing treatment by means of an inorganic sealing agent.
