Abstract

PURPOSE:To obtain a brazing filler metal having superior workability and stabilized high brazing strength by melting Ag, Cu and Ti in a high frequency melting furnace having a specified degree of vacuum, coating a casting mold made of Cr-Cu with a specified releasing agent and pouring the resulting molten alloy into the mold at a specified pouring speed. CONSTITUTION:Ag, Cu and Ti are melted in a high frequency melting furnace having 10<-4>Torr degree of vacuum. A casting mold made of 1wt.% Cr-Cu and preheated to 100 deg.C is coated with a liq. mixture of soot with white gasoline as a releasing agent and the resulting molten Ag-Cu-Ti alloy is poured into the mold, e.g., by about 4kg in 5-6sec to obtain an Ag-Cu-Ti alloy brazing filler metal for joining ceramics. The brazing filler metal does not break or crack during wire drawing.

(Conventional technology and its problems) Conventionally, a brazing filler metal made of AgCu-Ti alloy has been used for joining ceramics, but this brazing filler metal is made of AgC
The uTi matrix is soft (Hv 150) but hard (Hv 350). Because the CuTi phase is scattered in large particles, stress is applied unevenly during processing, and when processed into a wire with a small diameter, The wire broke at the CuTi phase part during wire drawing, and when it was processed into a thin plate, the CuTi phase part became uneven, cracked, or holed during rolling, resulting in extremely poor workability and low yield. It was bad. In addition, brazing had low strength, large variations, and was unstable.

(Function) As described above, in the manufacturing method of the present invention, Ag, Cu, and Ti are melted in a high frequency melting furnace with a degree of vacuum of 10-' Torr, so that Ti is difficult to oxidize. In addition, 1W of Ag-Cu-Ti alloy molten metal preheated to 100℃
Since it is cast into a mold made of t%Cr-Cu, the mold reaction is relatively mild. In other words, since there is a slight Cr oxide film on the mold surface, it fits well with the mold, and there is no scattering at the beginning of pouring (therefore, no particles are generated.Furthermore, before pouring the molten metal into the mold, there is no separation). Since a mixture of oil smoke and white gasoline is applied as a molding agent, the molding reaction takes place slowly, the casting surface is clean without any unevenness, and there are no large cavities inside.Also, approximately 4 kg of molten metal is 5
Since the casting speed is ~6 seconds faster, the cooling rate is faster, and the Cu-Ti intermetallic compound with a high melting point does not segregate or become liberated, so it does not grow into large particles. , it is uniformly and finely dispersed, and no nests are formed.
