<P>PROBLEM TO BE SOLVED: To provide a thermal spraying powder capable of securely forming a sprayed coating suitable under use where it is subjected to thermal impact in a corrosive atmosphere or an oxidizing atmosphere and under use where it is subjected to thermal impact in a state of being contacted with a member having reactivity with a base material. <P>SOLUTION: The thermal spraying powder contains yttrium-aluminum multiple oxide granulated-sintered particles obtained by subjecting raw material powder containing yttrium and aluminum to granulating and sintering. The total volume of fine pores with a diameter of ≤6 μm in the granulated-sintered particles is 0.06 to 0.25 cm<SP>3</SP>/g. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
