The service life of barium tungsten cathodes can vary due to many factors, including application environment, working conditions, electrode quality, electron emission intensity, etc. Typically, barium tungsten cathodes have a relatively long lifetime, but the exact lifetime depends on several factors:
Working environment: The working environment where the electrode is located will affect its service life. If there are high temperature, high vacuum, corrosive gas and other factors in the working environment, the electrode may suffer greater wear and tear, thus affecting its life.
Operating temperature: High temperature environments may affect the performance and stability of electrode materials, so using electrodes under high temperature conditions may shorten their life.
Electron emission intensity: The electron emission intensity and operating current density when using the electrode will affect the wear rate of the electrode. Higher electron emission intensities may cause the electrodes to wear out more quickly.
Quality and preparation process: The quality and preparation process of the electrode directly affect its service life. Better quality, well-prepared electrodes generally have a longer life.
Periodic use: If the electrodes are frequently switched on and off, or subjected to high current discharges many times in a short period of time, this may affect the life of the electrodes.
