摘要： A thermal spray powder of the present invention contains ceramic particles having an average particle size of 1 μm or more and 20 μm or less. The ceramic particles have a flowability index value FT of 3 or more measured by using a powder rheometer. The flowability index value FF is determined by measuring the maximum principal stress and the uniaxial collapse stress of the ceramic particles at normal temperature and normal humidity when 9 kPa of shear force is applied to the ceramic particles, and by dividing the measured maximum principal stress by the measured uniaxial collapse stress.
