Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a thermal spraying material for use in a metal spraying method, low in the porosity of a thermally sprayed body, excellent in hot wear resistance and high in compressive strength and hot shearing adhesive strength. SOLUTION: The thermal spraying material consists of 75-95 wt.% refractory oxide powder and 5-25 wt.% easily oxidizable metal powder, preferably Si powder. As a part of the refractory oxide powder, 2-50 wt.% petalite is used and the balance is one kind or more selected from the group consisting of SiO2 , Al2 O3 , ZrO2 and MgO.
