【Abstract】 Graphite electrodes were impregnated with boride solutions. The rates of oxidation loss of graphite electrodes with and without boride impregnation were compared through testing in a simulating furnace. The physical properties and surface morphology of specimens were also investigated after oxdation test. Results showed that the boride formed a continious antioxidation film on the surface of the graphite electrode at high temperatures. This continuous film filled up the surface pores and thus slowed down and suppressed the oxidation of the electrode. The consumption of the impregnated electrode could be decreased by about 15%.更多还原
