Thermal spray slurry, thermal spray coating and method for forming thermal spray coating

摘要

This invention provides a thermal spray slurry capable of forming a favorable thermal spray coating. The thermal spray slurry comprises a dispersion medium and thermal spray particles formed of at least one material selected from the group consisting of a ceramic, a cermet and a metal. 800 mL of the thermal spray slurry contains A kg of the thermal spray particles; when 800 mL of the thermal spray slurry in which the thermal spray particles are dispersed is supplied at a flow rate of 35 mL/min to a horizontally-placed tube and collected, the collected slurry contains B kg of the thermal spray particles; and the slurry has a supply efficiency index If of 70% or higher, determined by the next equation If (%)=B/A×100.
