Abstract
The invention discloses a processing method of a microwave output window for a high-power klystron. Each part is processed separately; a metal sealing sleeve and a welding positioning mold are placed together in a high-temperature furnace for heating; ceramic windows are inserted into the metal sealing In the sleeve, the ceramic window is positioned and fixed in the metal sealing sleeve with a welding positioning mold; the weldment is placed in the graphite mold, and then sealed at high temperature to obtain the seal of the microwave output window; on the outer periphery of the seal And close to the position of the ceramic window, use molybdenum tape and molybdenum wire to bind the sealing part, and then bind the solder wires at the upper and lower ends of the outer periphery of the sealing part respectively; set the upper output window reinforcement sleeve and the lower output window reinforcement sleeve respectively on the The upper and lower ends of the sealing part are finally placed in a high-temperature furnace for high-temperature welding to form the required microwave output window. The microwave output window manufactured by the processing method of the present invention improves the yield of the microwave output window, further improves the performance of the microwave output window, thereby ensuring the reliability of the microwave output window.
Description
technical field [0001] The invention relates to the field of high-temperature welding between metal materials and ceramic materials, in particular to a microwave output window for a high-power klystron and a processing method. Background technique [0002] In the prior art, the welding between two or more parts is generally assembled according to matching dimensions. In the microwave output window sealing parts for high-power klystrons, due to the large difference in thermal expansion coefficient between metal parts and ceramic windows, although the metal parts and ceramic windows cooperate well before high-temperature welding, the metal parts will There will still be a gap between the part and the ceramic window, so the welding yield of the microwave output window of the high-power klystron is low, so that the performance of the microwave output ceramic window is also poor. [0003] For example, the Chinese utility model patent (authorized announcement number 203339103, au...
