ABSTRACT

The present work is concerned with the modeling of titanium carbide coating growth on plain carbon steels by CVD, without the presence of hydrocarbons in the gas phase. The model is based on the simultaneous solution of the mass balance and diffusion equations of the system, allowing solutions for variable carbon concentration in steel. The comparison of the obtained numerical results with the experimental coating growth measurements of TiC coatings produced on plain carbon steels by conventional CVD, as well as by the Fluidized Bed CVD (FBCVD) process, indicates that they are in a good agreement.
