METHOD FOR COATING A SURFACE WITH A SELF-FLUXING ALLOY, WHICH COMPRISES HEATING THE SURFACE TO BE COATED TO A TEMPERATURE BETWEEN 400 AND 1000*F. BELOW THE MELTING POINT OF THE ALLOY TO BE SPRAYED, THE THEREAFTER PASSING A COMBUSTIBLE FLUID AND A COMBUSTION SUPPORTING FLUID ALONG A PATH OF FLOW WITH A SUBSTANTIAL LINEAR VELOCITY IN A DIRECTION TOWARD SAID SURFACE, FLAME-CONBUSTING THE FLUIDS ALONG SAID PATH OF FLOW, PASSING SAID SELF-FLUXING ALLOY IN FINELY DIVIDED, SOLID FORM ENTRAINED IN A SMALL VOLUME OF CARRIER GAS, INTO THE CENTRAL PORTION OF SAID FLAME AT A SMALL FRACTION OF THE LINEAR VELOCITY OF THE COMBUSTION GASES FOR PASSAGE THROUGH SUBSTANTIALLY THE HOTTEST PORTION OF THE FLAME, WHEREBY THE PARTICLES ARE FUSED AND ACCELERATED IN DIRECTION TOWARD SAID SURFACE AND SPRAYED ON SAID SURFACE.
