Beschreibung
Zusammenfassung:	PURPOSE: A method for direct application of a brazing flux to a brazing surface is provided. CONSTITUTION: The method for application of a brazing flux material to a brazing surface comprises the steps of (a) applying a brazing filler material directly onto a substrate by a kinetic spray application to form a brazing surface; (b) depositing a brazing flux material directly onto the formed brazing surface, wherein the step (a) comprises the steps of providing the brazing filler material as a particle mixture, entraining the particle mixture into a flow of a gas, the gas at a temperature insufficient to cause thermal softening of the particle mixture, directing the particle mixture entrained in the flow of gas through a supersonic nozzle placed opposite the substrate, and accelerating the particle mixture to a velocity sufficient to result in adherence of the particle mixture onto the substrate, thereby forming the brazing surface by a kinetic spray application.
