The arcjet performance of an arc heated wind tunnel is an important research field for thermal protection technology of the hypersonic flight environments and for disposal of industrial and medical waste in the environmental problem. The aerodynamic heating and shock layer around a blunt body under the arc heated flow have a lot of differences of chemical and thermal equilibrium. The research is aim to understand the thermal response for TPS material by using Huels type arc heater as the working gas for carbon dioxide. Virgin structure can be seen in the crystallization and lapping defect on surface, while structure after arc heating is changed recrystallization due to dissociate CO_2 gas. Shore hardness (HS) for SiC have 112 on surface of virgin material and 80 to 100 after ablation testing, respectively.
