简介 PROBLEM TO BE SOLVED : To provide a thermal-spraying powder suitable for depositing a sprayed coating having the excellent plasma-erosion resistance, and a method for depositing the sprayed coating. SOLUTION : The thermal-spraying powder contains particles comprising oxides of rare earth elements of any one of the atomic numbers 39, 59-70. The collapse strength of the particles in the thermal-spraying powder is ≥80 MPa, and the ratio of the bulk density to the true specific gravity of the thermal-spraying powder is ≥0.15. The particles in the thermal-spraying powder are preferably granulated and sintered ones, and the average grain diameter of the primary particles constituting the granulated and sintered particles is preferably ≤6 μm. The thermal-spraying powder is preferably used in applications of depositing the sprayed coating by plasma thermal spraying. COPYRIGHT : (C)2008, JPO&INPIT
