    Abstract: To provide thermal spray slurry capable of forming a thermal sprayed coating having a high adhesion strength on a thermal spray target surface of a substrate, disclosed is thermal spray slurry for forming a thermal sprayed coating on the thermal spray target surface by spraying the thermal spray slurry on the thermal spray target surface of the substrate, the thermal spray slurry containing: thermal spray particles having a 50% particle diameter D50 equal to or larger than 1 μm and equal to or smaller than 5 μm in volume-based cumulative particle diameter distribution; and a dispersion medium in which the thermal spray particles are dispersed. In addition, a ratio D10/Ra between a surface roughness Ra (unit: μm) of the thermal spray target surface and a 10% particle diameter D10 (unit: μm) of the thermal spray particles in the volume-based cumulative particle diameter distribution satisfies a formula “0.4

    Abstract: Provided is thermal spray slurry capable of forming a dense coating by thermal spraying while suppressing cracks. Thermal spray slurry includes: thermal spray particles having an average particle diameter of 1 μm or more and 10 μm or less and a dispersion medium in which the thermal spray particles are dispersed, and has a filling rate of 84 mass % or less, the filling rate being calculated by the following expression, filling rate (mass %)=B/A×100, where A denotes the mass of cake of the thermal spray particles obtained by precipitating the thermal spray particles out of the thermal spray slurry by centrifugation, and B denotes the mass of a dry matter obtained by removing the dispersion medium from the cake.
