The production process of barium tungsten cathodes involves multiple steps, requiring precise manipulation and control from material preparation to final assembly. The following are the basic steps in the production of general barium tungsten cathodes:
Material preparation: Choose high-purity tungsten alloy as the base material, usually containing a certain proportion of barium. At the same time, other auxiliary materials such as substrates, electron beam control elements, etc. are prepared.
Electrode design and mold preparation: According to the application requirements, design the shape and size of the electrode, and make a suitable mold. The mold is used to fill the material into the desired electrode shape.
Mixing and molding: Tungsten powder and barium compound are mixed, and the mixture is filled into molds for molding. Molding can adopt methods such as pressing and injection molding.
Pre-firing and sintering: The formed electrode is pre-fired at high temperature to remove part of the organic material and volatile components. Then, high-temperature sintering is performed to solidify the material into a hard electrode.
Electrode processing: Process the prepared electrode, such as cutting, trimming, etc., to ensure that the size and shape of the electrode meet the requirements.
Assembly: Assemble the prepared electrode with other necessary components to form a complete electronic device. This may involve joining methods such as welding, gluing, etc.
Testing and debugging: The finished barium tungsten cathode needs to be tested and debugged to ensure that it meets the expected electron emission and electron beam control requirements.
Quality Control: Throughout the production process, quality control is performed to ensure electrode consistency and stability. This includes raw material inspection, process control, finished product inspection, etc.
Packaging and delivery: After testing and quality control, the prepared barium tungsten cathode is packaged for transportation and use.
