つきが大きくて不安定であった。(Conventional technology and its problems) Conventionally, Ag-Cu-Ti has been used to bond the above ceramics.
A brazing filler metal made of an alloy is used, but this brazing filler metal has a soft (Hv150) but hard (Hv350) AgCuTi matrix, which is dotted with thick grains of Cu Ti phase, which causes stress during processing. When processed into a thin wire rod, the CuTi phase part breaks during drawing, and when processed into a thin sheet, unevenness occurs or cracks occur in the CuTi phase part during rolling. The machinability was extremely poor as holes appeared. In addition, the strength of brazing was low (it was unstable due to large variations).

The reason for adding 0.1 to 2 wt% of at least one of Ni and Ni is to uniformly and finely disperse the CuTi phase in the AgCuTi matrix. When the compound crystals of CuTi become large and processed into a plate shape with a thickness of 50 μm or less, the CuTi crystals fall off and form holes, and when it exceeds 2 wt%, TiFe,
This is because compounds such as T1Co and TiNi are created, and the Ti component necessary for joining ceramics sometimes does not move to the ceramic side during brazing, and therefore cannot be joined.

wt% is added and the CuTi phase is uniformly and finely dispersed, so when processed into the desired shape of the wax product, stress is applied uniformly and there is no possibility of bending or cracking. Further, as mentioned above (because the Cu Ti phase is uniformly and finely dispersed, the wettability with ceramics is improved, and the brazing strength is significantly increased).

がりのセラ 。The brazing filler metals for ceramics having the compositions shown in the left column of the table below are made through the steps of melting, casting, wire drawing, heat treatment, wire drawing, and cutting. Ceramic wires with a diameter of 7 mm and a length of 30 m shown in the center column of the table were placed in a vacuum (10-5 mmHg) furnace.
00 wires were brazed, and the brazed wire rods were subjected to a JIS A point bending test, and the strength of the brazing was measured, and the results shown in the right column of the table below were obtained. Also, the finished Cera before use.

たからに他ならない。(Leaving space below) As is clear from the table above, the brazing filler metal for ceramics and 7x bonding of the example has a larger brain size of the CuTi phase after processing before use than that of the conventional brazing filler metal for bonding ceramics. It can be seen that the brazing strength of ceramic wires brazed together with this brazing filler metal for ceramic bonding is higher and more stable than that of conventional brazing filler metal for ceramic bonding. It can be seen that This is simply because the CuTi phase of the ceramic bonding brazing material of the example was evenly and finely dispersed in the AgCuTi matrix, and the wettability with ceramics was improved.
