Barium tungsten electrodes are mainly used for certain specific applications, such as plasma welding or discharge machining, and their burnout rate (the loss rate of electrode materials caused by high temperature, arc or other factors during operation) is affected by many factors. The following are the main factors affecting the burnout rate of barium tungsten electrodes:

The emission efficiency of barium tungsten electrodes is the result of the coupling of multiple influencing factors, mainly involving material properties, preparation process, working conditions and environment, etc.

The factors affecting the surface roughness of barium tungsten electrodes involve multiple links such as material preparation, working environment, processing technology and post-treatment, and their formation mechanism is complex and interrelated.

The thermal expansion coefficient of barium tungsten electrode is mainly affected by factors such as material composition (ratio of barium to tungsten, doping elements), microstructure (grain size, porosity), preparation process (sintering, pressing, heat treatment) and use environment (temperature, atmosphere).

The grain size of barium tungsten electrode is crucial to its performance (such as electron emission ability, thermal stability and mechanical strength), and its influencing factors can be summarized as follows:

The arc erosion resistance of barium tungsten electrodes is the core indicator of its resistance to material loss, shape change or performance degradation under the action of arc, which directly affects its service life and stability. This ability is affected by multiple factors. The following is a systematic analysis from four dimensions: material properties, manufacturing process, use conditions and environmental interaction:

The corrosion resistance of barium tungsten electrodes is the comprehensive result of influencing factors such as material properties, working environment and use conditions. Optimizing electrode composition, improving manufacturing process, controlling working environment (such as using inert gas protection or reducing working temperature) and surface modification are effective ways to improve corrosion resistance.

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 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.
