New wetting mechanism induced by the effect of Ag on the interaction between resin carbon and AgCuTi brazing alloy

The interface microstructure between molten Ag-68.8Cu-4.5Ti (wt%) and resin carbon has been studied for the first time by transmission electron microscopy (TEM). It is revealed that the element of Ag promotes the interfacial reaction between carbon and Ti, and tends to aggregate at the interface between resin carbon and the production of TiC. As a result, good wetting of resin carbon by a thin monocrystalline Ag layer was observed.
