Embodiment 1
[0031] Component formula: the components and contents of the brazing filler metal are as follows: Ti: 40.0%; Zr: 25%; B: 0.2%; the rest is Cu.
[0032] Preparation:
[0033] (1) After pulverizing raw materials such as electrolytic copper block (Cu), sponge titanium (Ti), sponge zirconium (Zr) and copper-boron alloy, weigh the raw materials according to the above formula on an electronic balance;
[0034] (2) Place the ingredients according to the above formula in the WK type high vacuum Ar atmosphere protection non-consumable electric arc furnace. There are 5 copper crucibles in the electric arc furnace, and a pure Ti sample is placed in one of the crucibles, and the remaining four crucibles can be Put four ingredients of the same formula or different formulas at the same time;
[0035] (3) Before smelting, vacuumize the furnace to 10 -2 Pa, after flushing the furnace with argon for 3-4 times, vacuumize to 10 -2 Pa, refill with argon to -0.06MPa;
[0036] (4) Before formal...
Embodiment 2
[0047] Component formula: the components and contents of the brazing filler metal are as follows: Ti: 35.0%; Zr: 30%; B: 0.3%; the rest is Cu.
[0048] Preparation method: same as the preparation method of Example 1.
[0049] The melting temperature range of the brazing filler metal is 1102 ~ 1130K, using the amorphous brazing filler metal to vacuum braze Si 3 N 4 The bending strength of the ceramic joint at room temperature is 184MPa; the bending strength at high temperature is 123MPa (673K).
Embodiment 3
[0051] Component formula: the components and contents of the brazing filler metal are as follows: Ti: 45.0%; Zr: 20%; B: 0.1%; the rest is Cu.
