Composite materials on carbon-copper base have advanced electric and exploitation characteristics. They usually used as materials for sliding contacts for high-speed railway. Arc discharges appear during pantograph lowering process in pantograph-catenary system, so injection of contact material into discharge gap has place. Therefore, investigations of electric arc plasma between such composite electrodes can be useful for further optimization of materials. It would be very useful as well to examine the peculiarities of electric arc plasma and contacts’ working surface interaction. So, the aim of this work is spectroscopy investigations of electric arc discharge plasma between C-Cu composite electrodes. The mutual correlation of plasma properties and composition of contacts’ was found.
