摘要：

Measured temperature profiles for various oxide-tungsten cathodes and for pure tungsten cathodes are presented for high-current arcs burning in argon at atmospheric pressure. Temperature profiles are also presented for thoriated tungsten cathodes with different cathode cone angles, are currents and composition of the gas provided to the are. Evidence is also presented that the temperature and the behaviour of the cathode are sensitive to the oxygen concentration in the argon.
