    Abstract: A supersonic flame spray apparatus (1, 1′) utilizing an internal burner continuously feeds oxy-fuel products of com­ bustion through an extended length nozzle (7, 37) of dimi­ nished throat area (14, 35), supersonic expansion duct (15, 44) and an extended length nozzle passage (16, 36). The expansion from the throat (14, 35) to the end of the expand­ ing duct provides a gas velocity of well in excess of super­ sonic velocity. Solid material in rod or particle form is in­ troduced axially or radially into the supersonic gas flow at the end of the expanding duct (15, 44). This permits the extended length nozzle passage (16, 36) to have a relatively large diameter which prevents the solid material (4, 29) introduced to the flow to melt, reach the nozzle passage wall, and adhere thereto or abrade the nozzle wall, while permitting low pressure material injection into the gas flow stream (G).

    Abstract: Disclosed is a method of, and apparatus for, flame spraying particulate material utilizing the thermal energy of a very hot gaseous primary stream (27) produced in an oxy-fuel combustion chamber (11) combined with kinetic energy from a surrounding annular sheath of warm high velocity secondary air (28), the velocity of the said sheath of secondary air (28) being sufficiently close to the velocity of the primary stream (27) to avoid significant mixing between the two streams.

    Abstract: A fusion-bonded matrix coating on endless, flexible metallic casting belts for continuous casting machines is described. The fusion-bonded matrix coating comprises a nonmetallic refractory material interspersed substantially uniformly throughout a matrix of heat-resistant metal or metal alloy, for example nickel or nickel alloy. The coating is applied to a revolving belt (10,20) being supported and driven by pulleys (34,36) in a machine by thermally spraying a powdered mixture directly onto the roughened casting surface of the belt. The machine holds the revolving belt under tension and applies cooling to the rear surface of the revolving belt (10,20) opposite to the region where the thermal spray gun (66) is applying the coating to the belt (10,20), and causes the thermal spray gun (66) to traverse uniformly transversely across the belt. The result is to insulate and protect the underlying belt from intimate molten metal contact. The life of the coated belts is dramatically increased, and the surface quality and properties of the cast product are significantly improved.
