Abstract
Provided is a thermal spray material capable of, when used in a thermal spray operation for repairing a furnace wall of an industrial furnace or for other purposes, maintaining good post-repetition bondability with respect to a target surface to thereby prevent peel-off of a resulting thermally sprayed deposit, and improving initial ignitability while suppressing dust-generating property. The thermal spray material comprised a basic compound comprising at least one of a Ca component and an Mg component, a metal Si powder, and a silica-based or alumina-silica based powder. A content rate of a fraction constituting the basic compound and having a particle size of 0.15 mm or less is 30 mass % or more with respect to 100 mass % of the basic compound, and a content rate of a fraction constituting the metal Si powder and having a particle size of 20 μm or less is from 10 mass % to 25 mass % with respect to 100 mass % of the thermal spray material. Further, (the content rate (mass %) of the fraction constituting the metal Si powder and having a particle size of 20 μm or less, with respect to 100 mass % of the thermal spray material)/(a content rate (mass %) of the fraction constituting the basic compound and having a particle size of 0.15 mm or less, with respect to 100 mass % of the thermal spray material) is from 0.8 to 10, and a content rate of a fraction constituting the metal Si powder and having a particle size of 10 μm or less is 60 mass % or more with respect to 100 mass % of the metal Si powder.
