Application of Diffusion Brazing in Stockage of Vacuum Electronic Devices

The vacuum electronic device is the key components widely used in the fields of radar, navigation, electronic warfare and so on. Multi-brazing process is adopted in the manufacturing, and the leakage is easy to happen at many parts, such as brazed seams and base materials of tube shell, leading breakage of the devices. But now the brazing filler metal used in the stockage of vacuum electronic devices is very seldom. For the safe of vacuum electronic devices, stockage temperature must be lower than the brazi...
