| Abstract: | The mechanisms for chemical vapour deposition of TiN deposited on low carbon steel substrate, T10 steel substrate and Cr12MoV steel substrate under surface process limiting conditions were studied in this paper. The apparent activation energies of chemical vapoar deposition TiN deposited on these substrates and the apparent activation energies of Fe catalytic reaction were measured. The step of Fe surface diffusion on TiN coating surface was determined to be the limitiug step of the Fe catalytic reaction. A transformation temperature of the deposition mechanism for chemical vapour deposition of TiN deposited on T10 steel substrate and Cr12MoV steel substrafe was proposed and discussed. |
