  • Method of constantly restoring an electrode during plasma treatment of materials
    Patent number: 4810851
    Abstract: A method of electric arc treatment of materials by constantly restored solid and hollow electrodes in plasma-forming mixtures including hydrocarbons and carbon oxides, whereby carbon is deposited on an initial electrode (2) to form said constantly restored true-carbon electrode (1). Treatment is performed at a temperature of contact of the initial and true electrodes (2,1) not exceeding the temperature of carbon sublimation.
