METHOD AND SYSTEM FOR THICK-FILM DEPOSITION OF CERAMIC MATERIALS

摘要

A method of depositing a solid film on a substrate (28) in which a stream comprising particles suspended in a transport gas is moved through a heating zone (30). The particles are combined with the transport gas from a powder feeder (22) operatively coupled to a gas flow tube (16). The particle stream is directed toward the heating zone (30) by ejecting the powder stream from a nozzle connected to a distal end of the gas flow tube. A radiation source (34) is directed at the suspended particles as they move through the heating zone (30) so that the particles are heated to a molten state. The molten droplets are undercooled in a cooling zone (32) before impact with the substrate (28).
