- Abstract
The nanostructure around the wetting triple line in the Ag-Cu-Ti/SiC reactive wetting system was studied. The reaction product consisted of an upper separated Ti5Si3 layer more than 20 nm thick, and a lower TiC layer less than 10 nm thick was observed exceeding the front line of Ag-Cu-Ti brazing metal. At the top of the reaction product, the lower TiC layer was observed to project beyond the front line of the upper Ti5Si3 layer. In Ag-Cu-Ti/Si3N4 system, structural change around the wetting triple line as reactive wetting progressed has been reported, however, in the Ag-Cu-Ti/SiC system, the structure around the triple line did not change. The difference between the two systems was explained from the viewpoint of a stable phase change with the decrease of Ti activity as reactive wetting progressed.
