Abstract
The outstanding mechanical property of the diamond improves the working life of the diamond tool .There is high interfacial energy between diamond and general metals .as a result the diamond grain can't be wetted by generally low-melting-point alloys and diamond grain will peel off easily. In order to solve the above problems, we submit Ag-Cu-Zn alloy welding materials and a new Cu -based filler which adds Sn, Ti, then analyse the influence of Cu and Zn in Ag-Cu-Zn alloy welding materials, and analyse the function of Sn and Ti in Cu -based filler thus we solve the problem of wetting of the diamond in brazing process.
