Abstract
PURPOSE: To obtain a graphite electrode to be used for electrolytical oxidation or electrolytical reduction and which is extremely excellent in the oxidative wear resistant property, by forming a deposited layer of carbon on the surface of graphite electrode by heat-decomposing a hydrocarbon gas at a high temperature.
CONSTITUTION: Graphite electrode 8 to be treated held by graphite holder 9 is put into reaction chamber 5, and electrode 8 in chamber 5 is induction-heated to become red hot condition by supplying the electric current to high-frequency coil 6 installed on the outer periphery of chamber 5. Then, under this condition, hydrocarbon gas (e.g. C2H2Cl2) 3 is put into sealed can 1, the N2 gas is sucked as the carrier gas through sucking tube 2, and the reaction gas generated in can 1 is supplied into chamber 5. The above-mentioned reaction gas is decomposed in the vicinity of electrode 8 which has become red hot condition, and a homogeneous layer of carbon is formed on the surface of electrode 8 to have a thickness of, for example, 50W100μm. The electrode material thus obtained has about five-fold life compared with conventional graphite electrode materials.
