Abstract: We propose a model for estimating the influence of the relative content of the components in a composite cathode on the average charges of their ions in a vacuum-arc discharge plasma. Using the example a Ti$_{1-x}$Al$_x$ cathode, we show that an increase in the aluminum fraction in the cathode composition leads to a decrease in the average charge of titanium ions and an increase in the average charge of aluminum ions in the discharge plasma.
