The structure and properties of carbon materials formed 
in an arc between graphite electrodes in the case of decreased pressure 
of a buffer gas are considered. A mechanism of formation of a cathode 
coating by positively charged carbon macroparticles is proposed. The 
particles melt upon collision with the cathode surface and then the 
stage of growth of a coating from a liquid phase occurs.
