摘要
A cermet powder for thermal spray coating, which is sprayed on a roll surface of a conveyer roll inside a furnace for heat treating a high tensile strength steel strip thereby to form a coating film, comprises: an alloy powder containing 3 to 8 mass % of Al, 16 to 25 mass % of Cr, 0.1 to 1 mass % of Y, and at least one of Co and Ni as the residual, with respect to the whole amount of the cermet powder; and a ceramic powder containing at least one of 1 to 5 mass % of a boride and 5 to 10 mass % of a carbide, with respect to the whole amount of the cermet powder.
