Refractory carbide coated carbon materials are widely used in current fusion devices.To relieve intense thermal stresses at interfaces resulted from heat loading and unloading, TiC/C functionally graded materials (FGMs) were designed by finite element methods.According to the design, TiC/C buffer layer was fabricated by chemical vapor deposition.Scanning electron microscopy (SEM) was used to study morphologies and cross-section micrograph of TiC/C materials.Results showed that interfaces between adjacent layers were ambiguous in TiC/C FGMs with 3 interlayers.That would be beneficial to improvement of soundness and thermal shock resistance of coatings.Thermal cycles in plasma environment suggested that the asprepared TiC/C FGMs had better thermal shock resistances and no penetrating cracks were observed.
