Abstract

PURPOSE:To improve wetting of the silver solder to prevent soldering defects, by limiting the mixture ratio of flux components for silver soldering of a metal carbide group ultrahard alloy. CONSTITUTION:The flux where mixture components are 5-30wt% borax, 15- 50wt% boric acid, 50-55wt% acid potassium fluoride, 5-20wt% potassium borofluoride, and 1-15wt% potassium hydrogencarbonate is used to perform silver soldering of a metal carbide group ultrahard alloy. The borax functions for oxidation prevention, and the boric acid functions for oxidation prevention and reduction. The acid potassium fluoride enhances the reduction function and lowers the flux melting point. The potassium borofluoride cleans the surface of the base metal. The potassium hydrogencarbonate improves the coating function.
