    摘要: A method (8) for brazing a surface (10) of a metallic substrate (12) having a generally passive metal oxide layer (18) including steps for activating said surface (10) of said metallic substrate (12) by machining said metallic substrate (12) with a hard metal tool, grit blasting powdered particles (14) of an activating material on said surface (10), and wetting the grit blasted surface (10) of the metallic substrate (12) with a filler material (16) at a brazing temperature, wherein said activating material is reactive with said metal oxide layer (18) at said brazing temperature.
