ON THE FEATURES OF THE INFLUENCE OF IMPURITIES OF THE ELECTRODE MATERIAL ON THE ELECTRICAL CONDUCTIVITY OF THE PLASMA OF PULSE ELECTRICAL DISCHARGE IN WATER

he influence of impurities of the electrode material on the electrical conductivity of pulsed discharge plasma in water is considered. Experimental studies of electrical conductivity were conducted and calculations were performed based on the Grade method of moments. It is shown that a small amount of metal and carbon impurities can significantly change the value of the plasma electrical conductivity coefficient compared to the case of pure water vapor. It is found that metal and carbon impurities can cause both an increase and a decrease of the plasma electrical conductivity, which is related to the processes of interparticle collisions and the presence of clusters.
