A METHOD OF DEPOSITING FLUX OR FLUX AND METAL ONTO A METAL BRAZING SUBSTRATE
Application IN/PCT/2001/00961 published 2006-02-10, filed 2001-09-14
The present invention is directed to a means for the surface preparation of a metal or metal alloy substrate. In the process of the present invention, a stream of a mixture of flux particles and metal particles is hurled at the substrate at velocities effective for flux adhesion to the surface. The velocities of the particle stream is adjusted so that the flux particles adhere to the surface and the metal particles bounce off the surface. At higher temperatures and velocities, the metal particles are co-deposited with the flux (FIG.1).
