Control of the Process of Electrodischarge Synthesis of Nanocarbon from Gaseous Hydrocarbons on Metal Surfaces

Abstract

A system for controlling the process of the high-voltage high-frequency electric discharge synthesis of nanocarbon on metal surfaces in a carbon gas medium has been developed. The criteria that determine the production mode of the synthesis of nanocarbon are defined. The synthesis control is performed according to the minimax optimality criterion. It allows the current value in the range of the production mode of the synthesis of carbon nanomaterials with an onion-like structure to be maintained. The control of the movement of the metal surface sample with respect to the electrode in the course of synthesis ensures the uniformity of coating the surface with a layer of a synthesized nanocarbon material.
