At present, the possible connection methods are tantalum welding, solid phase diffusion bonding and transient liquid phase diffusion bonding. However, these methods are also in many disadvantages: the connection temperature of the soldering is usually low', but the soldering (10) point is generally low, and the soldering It is difficult to make joints that can be used at high temperatures; for _diffusion connections, it is necessary to achieve a high temperature for the connection with the ceramics, and the holding time is often greater than 1 hour at the connection temperature I, the processing time is long, and the energy consumption is large = The liquid phase diffusion bonding method to achieve tin bronze and oxygen f gate must make the liquid phase appear in both, and the melting point and diffusion performance between the tin bronze and the oxygen ceramics are kept in a short time, and the connection time is too long. The main 'expenditure' needs to extend the liquid phase overflow to the outside of the joint, affecting the quality of the joint.

The DC pulse power supply has a pulse width ratio of 1 2 : 2 and a maximum current of up to 50,000 A 〇 [0020] (6) The graphite mold 50 is placed in the furnace 13 of the discharge plasma sintering apparatus 10, and used The indenter 51 and the lower indenter 52 are respectively aligned with the positive and negative electrodes 12 of the discharge plasma sintering apparatus 10, and the furnace 13 is evacuated to a vacuum of 6 to 10 Pa, and the DC pulse power source 14 is turned on to warm the workpiece, and the following process is set. The parameter is to discharge plasma connection of the workpiece: the axial pressure is 20~40MPa, the heating rate is 50~300°C/min; when the temperature is 700~900°C, the temperature range is maintained for about 20~40 minutes, This temperature is the connection temperature. [0021] (7) After the cooling, the connecting member of the tin bronze and the alumina ceramic is taken out. [0022] The above method for connecting tin bronze to alumina ceramics adopts a discharge isochronization 099125823 Form No. A0101 Page 8 / 18 pages 0992045311-0 201206861 Ο Sub-body sintering equipment 10 (or pulse current heating equipment) A pulse current is applied to heat the workpiece, and the upper portion 532 and the lower portion 534 of the graphite mold 5 are designed to have different cross-sectional areas perpendicular to the current direction, so that the oxidized glass member 30 is located at the upper portion 532 having a smaller cross-sectional area, and tin The bronze member 20 is disposed on the lower portion 534 having a larger cross-sectional area. When the current passes through the graphite mold 50, the current density of the upper portion 532 is greater than the current density of the lower portion 534, so that the tin bronze member 2〇 and the alumina ceramic member are located in the same mold. 3〇 is subjected to different current densities, and the current density acting on the alumina ceramic member 3大于 is greater than the current density acting on the tin bronze member 20, thereby causing the temperature rise rate of the alumina ceramic member 3〇 to be larger than that of the tin bronze member 2〇. The temperature rise rate is increased, so that the tin bronze member 20 and the alumina ceramic member 30 can be softened at the same time to the respective softening temperatures, thereby shortening the connection time. 1 [0023] Ο Another 'under the pulse current' discharge between the tin bronze member 2 〇 and the oxidized glass member 30 produces a hot plasma 'the plasma cleans and activates the surface of the workpiece' to enhance the surface of the workpiece Atomic diffusion capacity. Moreover, under the action of the pulse current, the tin bronze member 20, the oxidized ceramic member 3, and the metal intermediate layer 40 generate self-heating and partial discharge heat, which promote the physical and chemical reaction of the contact interface and the diffusion of atoms. In addition, under the axial pressure, the contact area between the workpieces is continuously increased, and finally the close contact is made and connected together. [0024] The method for connecting the tin bronze to the alumina ceramic is to sequentially place a copper foil, a nickel foil and a titanium foil as a connecting medium between the tin bronze member 20 and the alumina ceramic member 30, since nickel and copper have similar expansion coefficients. Conducive to the combination with the tin bronze piece 20' and the expansion coefficient of Qin is relatively low, and the expansion coefficient of the oxidized Ming Tao is relatively close, and Qin's high temperature activity is high, which is beneficial to the oxidation of Ming Tao actually 099125823 Form No. A0101 Page 9 / A total of 18 pages 0992045311-0 201206861 pieces of 3 0 combination.

The connection portion of the crucible is 6〇. The connecting portion 60 includes a copper layer 61, a first transition layer: .6.2'-recording layer β3, a second transition layer 64, a titanium layer 65, and a third transition layer 66. The copper layer 61 is directly connected to the tin bronze member 20. Since the main composition of the copper and tin bronze member 2 is relatively close, no significant transition layer is formed between the copper layer 61 and the tin bronze member 20. The first transition layer 62 is located between the copper layer 61 and the nickel layer 63, which is a transition layer between the copper layer 61 and the nickel layer 63. The first transition layer 62 is mainly composed of a solid solution of copper and nickel and a copper-nickel intermetallic compound, and has a thickness of about 20 to 40 mm. The second transition layer 64 is located between the nickel layer 63 and the titanium layer 65, which is a transition layer between the nickel layer 63 and the titanium layer 65.

The third transition layer 66 is located between the titanium layer 65 and the alumina ceramic member 30. The third transition layer 66 is mainly composed of a titanium oxide compound, a titanium aluminum intermetallic compound and a small amount of titanium aluminum solid solution, and has a thickness of about 10 〜20mm 连接 The joint portion 60 of the tin bronze and alumina ceramic connecting member 100 is dense and uniform, free from cracks and voids. The tin bronze/alumina ceramic interface of the tin bronze and alumina ceramic connector 100 has been tested to have a shear strength of 099125823.
