The most important techniques in the synthesis of SiC/C function gradient material (FGM) are to control the SiC/C ratio and to obtain the moderate deposition rate. For these, various gas systems and flow rates were attempted and evaluated. It turned out that the CH4+SiCl4+H2 system was suitable for the deposition of SiC-rich layers, the C3H8+SiCl4+Ar system for the deposition of carbon-rich layers, and the C3H8+SiCl4+H2+Ar system was good to deposit the layers between them.
