Title:
PRODUCTION METHOD FOR THERMAL SPRAY PARTICLES, TURBINE MEMBER, GAS TURBINE, AND THERMAL SPRAY PARTICLES
Document Type and Number:
WIPO Patent Application WO/2016/129522
Kind Code:
A1
Abstract:
Provided is a production method for thermal spray particles that form a ceramic layer wherein longitudinal cracks extending in the thickness direction are dispersed in the surface direction of the ceramic layer, and a plurality of pores are included inside the ceramic layer. In a production method for thermal spray particles: the solid content concentration of a slurry (13) is regulated to 75-85 wt%; the slurry (13) is supplied to a disk-shaped atomizer (12) of a spray drying device (10); the protrusion speed at which the slurry (13) protrudes from the atomizer (12) is set to 60-90 m/second; the slurry (13) heat-treats dried thermal spray particle bodies (22); and thermal spray particles comprising YbSZ, of which 50% of the particle diameters in the cumulative particle-size distribution are from 40 μm to 100 μm, are produced.
