Abstract: A method of forming an SiC or SiC/Si3N4 coating layer on a bare graphite substrate via a solid-vapor process is disclosed. Synthesis of the SiC coating layer on the graphite substrate is accomplished by reaction of SiO vapor and carbon (C) of the graphite, and that of the SiC/Si3N4 coating layer is accomplished by reaction of SiO vapor, N2 and C of the graphite. Thickness of the SiC coating layer is affected by porosity of the graphite substrate, reaction temperature, and dwell time. By controlling the reaction temperature, hardness of the SiC coating may be increased to 10-15 times that of the bare graphite substrate. The SiC/Si3N4 coating is much thinner than the SiC coating and has a higher surface hardness. Thermal oxidation tests show that the SiC or SiC/Si3N4 coated substrate exhibits improved oxidation resistance over bare substrates. In particular, the SiC/Si3N4 coated substrate shows outstanding resistance to thermal oxidation.
