An integrated mathematical model depicting chemical vapor deposition( CVD) process of SiC coating on specialshaped components was developed.The model was proposed to simulate deposition behavior of SiC coating on typical special-shaped components.The calculated results indicate that the components with a slope have significant influence on the CVD process of SiC coating.Small angle between the slope and horizontal plant is beneficial to the quality control of CVD SiC.In terms of the components with step sha...
