POWDER FOR THERMAL SPRAYING THERMAL SPRAYED COATING AND METHOD FOR FORMING THERMAL SPRAYED COATING
본 발명의 용사용 분말은, 1㎛ 이상 20㎛ 이하의 평균 입자경을 갖는 세라믹 입자를 함유한다. 파우더 레오미터를 사용하여 측정되는 세라믹 입자의 유동성 지표값 FF는 3 이상이다. 유동성 지표값 FF는, 상온 상습하에서 세라믹 입자에 9㎪의 전단력을 부여한 때의 세라믹 입자의 최대 주응력 및 단축 붕괴 응력을 측정하고, 최대 주응력의 측정값을 단축 붕괴 응력의 측정값으로 제산함으로써 구해진다.
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.
