Abstract The cyclic oxidation behavior of the Ti--60 titanium alloy, and Ti--48Al and Ti--48Al--12Cr (atomic fraction, %) coatings at 800℃ were studied. The results showed that the Ti--60 titanium alloy showed poor oxidation resistance in the process of cyclic oxidation at 800℃, occurring with oxidation scales fall. The Ti--48Al and Ti--48Al--12Cr coatings showed good oxidation resistance at 800℃. For the Ti--48Al--12Cr coating, the weight gain is much less than that of the Ti--48Al coating, showing better cyclic oxidation resistance.
