Abstract
The erosion and deposition behavior of the SiC coating on plasma facing components were simulated by the modified Erosion and Deposition based on DYnamic model (EDDY code), using typical edge plasma parameters for the Experimental Advanced Superconducting Tokamak (EAST). Compared to non-doped graphite, less deposition and erosion were observed on the SiC coating. Effects of carbon chemical sputtering yield, impurities concentration and edge plasma parameters have also been examined. Results showed that, the carbon deposition rate decreased as the electron temperature increased at low plasma density, while increased with the electron temperature at high plasma density.
