  • Composite thermal spray powder of metal and non-metal
    Patent number: 5122182
    Abstract: Two constituent powders of a powder blend for thermal spraying are in the form of composite particles containing subparticles of nickel alloy and benoite for clearance control coatings. The composite particles are formed by spray drying. In one embodiment the volume percentage of metal in one constituent powder is at least 25% greater than in the other powder. In another embodiment the difference is about 10% by volume, and the alloy rich constituent has alloy subparticles sufficiently large to act as core particles to which the finer subparticles of bentonite are bonded.
