Thermal spray particles and sprayed components

摘要

Rare earth-containing compound particles of polyhedral shape having an average particle diameter of 3-100 mum, a dispersion index of up to 0.5, and an aspect ratio of up to 2 can be thermally sprayed to form an adherent coating, despite the high melting point of the rare earth-containing compound. A sprayed component having the particles spray coated on a substrate surface is also provided.
