Abstract: Isothermal oxidation behaviour of two Ti(C,N)-based cermets (TiC–10TiN–16Mo–6.5WC–0.8C–0.6Cr3C2–(32–x)Ni–xCr, x = 0 and 6.4 wt%) was investigated in air at 800–1100 ℃ up to 2 h. Mass gains exhibited neither linear nor parabolic law during isothermal oxidation. The oxide scales formed at 800–1100 °C were multi-layered, consisting of NiO outerlayer, NiTiO3 interlayer and TiO2-based innerlayer. The internal oxidation zones formed at 1000–1100 C consisted of Ti-based, Ni-based and Mo-based complex oxides. Cermet with 6.4 wt% Cr exhibited superior oxidation resistance.
