    Abstract: The flame spraying of the flame spray powder which has been formed by spray drying of a slip or slurry of fine particles of a flame spray material. This flame spray powder has individual particles which are of substantially spheroid shape, of a size between about 20 mesh and 1 micron, and are formed of multiple subparticles bound together without fusion by a spray-dried binder and having a crush resistance of at least 0.7 grams. For the spray drying, fine particles of any known or conventional flame spray material or combination thereof, such as metals, ceramics, carbides, etc., suspended in a slip or slurry of a liquid, preferably water, with a suitable binder and preferable auxiliary agents, is atomized into a hot drying gas stream forming the spheroid larger composite particles.
