摘要：
The effect of argon and krypton pressure on the characteristics of a rod cathode of thoriated tungsten in a stationary arc discharge is investigated. The dependences of basic integral parameters of cathode are measured, such as the heat flux to electrode, the electron work function, the temperature, the current density, and the specific erosion at current loads of 20–150 A in the pressure range of 2.66 × 103−105 Pa. The significant effect of pressure on the level of specific erosion of cathode is observed.
