摘要：

Pure silicide coating and Y-Ce modified silicide coating were prepared on Ti-6Al-4V alloy by pack-cementation process. The structures as well as the isothermal oxidation behaviors of the coatings were comparatively studied. The results showed that both pure silicide coating and Y-Ce modified silicide coating prepared at 1080 degrees C for 4 h were composed of a TiSi2 outer layer, a TiSi middle layer and a Ti5Si4 inner layer. The oxidation tests showed that the Y-Ce modified silicide coating possessed much better oxidation resistance than the pure silicide coating at 1000 degrees C, implying the beneficial effects of Y and Ce on the oxidation resistance of the coating.
