Embodiment 1

[0017] (1) Put Cu, Co, and Ni in a vacuum melting furnace, evacuate the furnace to 1Pa, heat to 1350°C, and then cool to room temperature to make a copper-cobalt-nickel master alloy;

[0018] (2) Put the copper-cobalt-nickel master alloy together with Ag, Ge, Nd, and Yb components into a vacuum melting furnace, evacuate to 0.4Pa, and heat to 1300°C; after it forms a melt, cool down to 1000°C, Pour the molten liquid into the shaping mold, and after the temperature drops to room temperature, take the shaping mold out of the vacuum furnace to obtain the ingot required for processing the sealing material;

[0019] (3) When the ingot is rolled to a thickness of 1~2mm by a rough rolling mill, it is coiled and placed in a heat treatment furnace, and the temperature is raised to 700°C for 2 hours, then lowered to room temperature, and then rolled to a thickness of 0.03~0.2mm by a finishing mill , trimmed and stamped to the desired shape.

Embodiment 2

[0021] (1) Put Cu, Co, and Ni in a vacuum melting furnace, evacuate the furnace to 0.5Pa, heat to 1200°C, and then cool to room temperature to make a copper-cobalt-nickel master alloy;

[0022] (2) Put the copper-cobalt-nickel master alloy together with Ag, Ge, Nd, and Yb components into a vacuum melting furnace, evacuate to 0.2Pa, and heat to 1100°C; after it forms a molten liquid, cool down to 900°C, Pour the molten liquid into the shaping mold, and after the temperature drops to room temperature, take the shaping mold out of the vacuum furnace to obtain the ingot required for processing the sealing material;

[0023] (3) When the ingot is rolled to a thickness of 1~2mm by a rough rolling mill, it is coiled and placed in a heat treatment furnace, and the temperature is raised to 600°C for 5 hours, then lowered to room temperature, and then rolled to a thickness of 0.03~0.2mm by a finishing mill , trimmed and stamped to the desired shape.

Embodiment 3

[0025] (1) Put Cu, Co, and Ni in a vacuum melting furnace, evacuate the furnace to 0.1Pa, heat to 1280°C, and then cool to room temperature to make a copper-cobalt-nickel master alloy;

[0026] (2) Put the copper-cobalt-nickel master alloy together with Ag, Ge, Nd, and Yb components into a vacuum melting furnace, evacuate to 0.04Pa, and heat to 1200°C; after it forms a molten liquid, cool down to 950°C, Pour the molten liquid into the shaping mold, and after the temperature drops to room temperature, take the shaping mold out of the vacuum furnace to obtain the ingot required for processing the sealing material;

[0027] (3) When the ingot is rolled to a thickness of 1~2mm by a rough rolling mill, it is coiled and placed in a heat treatment furnace, and the temperature is raised to 650°C for 4 hours, then lowered to room temperature, and then rolled to a thickness of 0.03~0.2mm by a finishing mill , trimmed and stamped to the desired shape.

Abstract

The invention discloses a multicomponent alloy sealing-in material which comprises components by mass percentage: 6-73% of Ag, 26-30.5% of Cu, 0.5-2% of Ge, 0.1-1% of Co, 0.2-0.5% of Nd, 0.1-2.5% of Ni, and 0.1-0.5% of Yb. The multicomponent alloy sealing-in material is high in cleanliness, good in sealing-in airtightness, and high in corrosion resistance and oxidation resistance.

Description

technical field [0001] The invention relates to a sealing material for vacuum electron tubes in the vacuum electronics industry, in particular to a silver, copper [0002] Germanium, cobalt, ytterbium, nickel, neodymium alloy sealing material. Background technique [0003] In the vacuum electronic sealing industry, due to the high frequency of use of vacuum electron tubes and the need to maintain a vacuum state, the airtightness and sealing materials of vacuum electronic tube sealing, especially the sealing materials of ceramics and metals, and metals and metals The requirements are relatively high. The existing conventional sealing materials are not ideal for vacuum tubes with extremely high frequency of use. For example, the airtightness of conventional sealing materials after sealing is not satisfactory, and the anti-oxidation and anti-corrosion properties are not good enough under long-term high-frequency operation. Contents of the invention [0004] In view of the ...
