ABSTRACT:
A method of depositing a solid film on a substrate in which a stream comprising particles suspended in a transport gas is moved through a heating zone. The particles are combined with the transport gas from a powder feeder operatively coupled to a gas flow tube. The particle stream is directed toward the heating zone by ejecting the powder stream from a nozzle connected to a distal end of the gas flow tube. A radiation source is directed at the suspended particles as they move through the heating zone so that the particles heated to a molten state. The droplets are undercooled in a cooling zone before impact with the substrate.
