Low-temperature plasma refers to plasma generated at relatively low temperatures (usually room temperature to several hundred degrees Celsius). It has attracted much attention due to its unique advantages in materials science, biomedicine, environmental science and aerospace technology.

The realization of the machining accuracy of barium tungsten electrodes requires comprehensive control of multiple influencing factors such as material properties, machining parameters, environmental conditions, operating skills and quality inspection.

The application of barium tungsten electrode in high-frequency plasma benefits from its unique material properties: tungsten provides stability and heat resistance, and barium reduces the work function to improve the electron emission ability. This electrode is an efficient electron emission source in high-frequency plasma systems, which can help generate and maintain stable plasma and is widely used in material processing, surface treatment and plasma chemistry.

The thermal cycle performance of barium tungsten electrodes refers to their ability to maintain structural integrity and performance stability during repeated heating and cooling. The main influencing factors are as follows:
