| Abstract: | Deposition process of SiC on the surface of a heat resisting steel OCr19Ni9 by CVD was investigated. High temperature corrosion behaviours of OCr19Ni9, TiC coating and SiC coating in an O2-Br2-Ar atmosphere were compared. The corrosion kinetics of SiC is interpreted in terms of thermodynamics. It is proved that a dual layer film of TiC/SiC deposited on the heat resisting steel can greatly improve its high temperature corrosion resistance. |

| Keywords: | SiC films CVD high temperature corrosion O2-Br2-Ar atmosphere. |
