This work deals with the analysis of mechanism of nanostructured composite formation at joint electric-arc spraying of graphite electrodes with addition of various elements. It is shown that the morphology of nanoparticles, formed at condensation of carbon vapors with the additive elements that have similar pressures of saturated vapors, can vary significantly. This difference is explained by chemical interaction of an additive element with the carbon matrix.
