Claim Text:
1. A method of manufacturing powder for forming a thermal-sprayed layer, the method comprising the steps of: preparing (1) mixed powder consisting of 4.0 to 6.5 mass % of B, 39.0 to 64.0 mass % of Mo, and 7.5 to 20.0 mass % of Cr, a balance being 5 mass % or more of Ni and unavoidable elements, wherein the ratio by mass % of Mo to B is 8.9-11.1, or (2) mixed powder which contains 4.0 to 6.5 mass % of B, 39.0 to 64.0 mass % of Mo, 7.5 to 20.0 mass % of Cr, and 0.1 to 10.0 mass % of V, a balance being 5 mass % or more of Ni and unavoidable elements, wherein the ratio by mass % of Mo to B is 8.9-11.1; wet grinding the mixed powder to make a wet ground powder; granulating the wet ground powder to make a granulated powder; and sintering the granulated powder at a temperature of 1000 to 1150° C. for 30 to 90 minutes, at a temperature elevation speed in the sintering of 0.5 to 60° C./min.
