Correlation of the experimental data obtained on several MHD devices reveals the main features of the behavior of cathode spots in open-cyle MHD channels. The parameters of the cathode spots in MHD channels operating in different conditions were measured. The characteristics of the discharge and erosion of the electrodes were greatly affected by the film of seed compounds deposited on the electrode surface by the plasma stream in the channel of an open-cycle MHD generator. Data were obtained for the erosion of electrodes of different materials. The most probable erosion mechanism for copper electrodes is discussed.
