Description
Oxidation-resistant coating on the graphite anode sample was investigated experimentally. Boride coatings with anti-oxidation property were characterized via scan electron microscope (SEM) and oxidation weight loss experiments, respectively. The results show that the coating is in glassy state at around 800 deg. C, resulting in easily impregnating into pores of graphite anode sample. The coating with strong adhesive is compact and without cracks. At the temperature of 750 deg. C or above, the oxidation weight loss results indicate that the oxidation loss rate of graphite with coating is much lower than that of without coating. With the increase of temperature, the variation of oxidation weight loss of graphite with boride coating is a small amount, which suggests that the coating has the characteristic of excellent oxidation-resistant
