To improve the thermal fatigue performance of barium tungsten electrodes, multi-scale coordinated optimization is required: regulating the composition from the atomic scale, designing the strengthening phase at the microscale, and optimizing the geometry at the macroscale to reduce stress concentration. The factors affecting the thermal fatigue performance of barium tungsten electrodes can be summarized into the following key aspects:

The antioxidant properties of barium tungsten electrodes are affected by many factors, including material formula, preparation process, surface treatment, use environment, etc.

The conductivity of barium tungsten electrode is the result of the combined effect of material composition, preparation process, working environment, surface state and electric field conditions. These influencing factors need to be comprehensively optimized in practical applications.

Barium tungsten electrode is an electrode material widely used in the field of electron emission, and its surface microstructure has a decisive influence on electron emission performance, thermal stability and service life. The surface microstructure mainly includes characteristics such as grain size, porosity, surface morphology and microscopic defects, which directly affect the work function, electron emission uniformity and thermal fatigue resistance of the electrode.
