摘要： PURPOSE: To join securely a sintered hard material and metallic material at a low temp. by sandwiching a green compact composed of the specific compsn. consisting of Ti, etc. as well as Sn and Cu and heating the same in a vacuum to convert the green compact to a liquid phase then pressurizing the materials.
CONSTITUTION: 3W30wt% powder of ≥1 kinds among Ti, Cr, Zr, Mn, Mo and W, 5W20% Sn powder and the balance Cu powder and additive metallic powder, etc. of ≥1 kinds among Ag, Zn, V, Nb, Ta and B to be added according to need are compaction-molded. Such green compact is sandwiched betweenthe sintered hard material such as diamond or cubic boron nitride and the metallic powder and is heated to about 700W750°C in about 10
-2 W10
-3 Torr vacuum by which the green compact is converted to the liquid phase. These materials are thereafter pressurized under about 10W100kg/cm
2 and are cooled, by which the sintered hard material and metallic material are securely joined without cracking and performance deterioration.
