摘要： PROBLEM TO BE SOLVED: To provide a thermal spray material from which a thermal spray film excellent in corrosion resistance to an acid such as hydrochloric acid is manufactured.SOLUTION: A thermal spray material comprises granules containing an oxyfluoride (LnOF) of a rare earth element and a fluoride (LnF) of a rare earth element. The thermal spray material of 50 g is put in 500 mL of hydrochloric acid of 3 mol/L at 40±5°C, kept at 40±5°C for 2 hours under stirring and then subjected to solid-liquid separation to obtain a liquid. The C/S value (unit: mol g/(mL) of the liquid is 0.04 or less, where C (unit: mol/L) indicates a concentration of the rare earth element in the liquid; and S (unit: m/g) indicates a BET method specific surface area of the thermal spray material. The angle of repose of the thermal spray material is preferably 40° or less. The differential angle of the thermal spray material is preferably 10° or less.

摘要： PROBLEM TO BE SOLVED: To provide a thermal spray material excellent in flowability when supplied in a flame and capable of easily obtaining a uniform spray film.SOLUTION: The thermal spray material of the present invention consists of a granule including yttrium oxy fluoride (YOF). The granule may further include yttrium fluoride (YF). An oxygen content of the granule is suitably 0.3-13.1 mass%. The fracture strength of the granule is suitably 0.3 MPa or more and less than 10 MPa. Some yttrium (Y) in the granule may be replaced by at least one kind of rare earth elements (Ln) except an yttrium element. The mole fraction of Ln to a total of Y and Ln in that case is suitably 0.2 or less.
