Abstract The Si-B composite coatings with different doping amount of CeO₂ were prepared on the surface of molybdenum substrate by two-step pack cementation methods. The effect of CeO₂ doping on phase structure and cross-section morphology of Si-B composite coatings before and after oxidation at 1 150℃ were analyzed by XRD, EDS and SEM. The oxidation kinetics of Si-B composite coatings before and after CeO₂ doping oxidized at 1 150℃ for 160 h were studied by mass-loss method. The results showed that appropriate doping amount of CeO₂ had certain per-meation effect on Si element in pack cementation process. The Si-B composite coatings with thick, uniform and dense structure were obtained when the doping amount of CeO₂ was fixed at 1wt%. However, the thickness of Si-B composite coatings decreased with the further increase of CeO₂ doping amount. The oxidation rate constant (1.48×10^-4 mg²/(cm⁴·h))of the doped Si-B composite coating oxidized at 1 150℃ for 70 h was significantly lower than that without CeO₂ doping, which indicated that the Si-B composite coating doped with CeO₂ has better high temperature oxidation resistance.

Key words： molybdenum two-step pack cementation Si-B composite coating CeO₂ doping
