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.

Thermal spray slurry comprising:
- at least two raw material slurries comprising thermal spray particles having a different distribution of volume-based cumulative particle diameter and 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, the thermal spray slurry having 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 mass of a cake of the thermal spray particles obtained by precipitating the thermal spray particles out of the thermal spray slurry by centrifugation at a temperature of 25° C. at a rotary speed of 20,000 rpm for 10 hours, and B denotes mass of a dry matter obtained by removing the dispersion medium from the cake by heating the cake at 120° C. for 24 hours.
