PROBLEM TO BE SOLVED: To make the adhesion between sprayed coating and a base material excellent while the sprayed coating is made porous one high in thermal insulation properties with respect to a thermal spraying-coated member in which the surface of a base material such as ceramics, metal or the like is thermally sprayed with a thermal spraying coating material to form sprayed coating. SOLUTION: The compsn. of a thermally spraying coating material is composed of, by weight, 0.2<=Li2 O<=10.0, 51.5<=SiO2 <=64.5, 2.0<=CaO<=46.0 and 1.0<=Al2 O3 <=32.0, or as for the thermally spraying coating material, calcium silicate crystals and lithium aluminosilicate are used as the main components, and the compounding ratio of the lithium aluminosilicate crystals is regulated to 5 to 95 wt.%, by which the porosity of sprayed coating is regulated to 10 to 40%. |
