摘　　要：研究了Ti-60钛合金及Ti-48Al和Ti-48Al-12Cr(原子数分数,%)两种涂层在800℃的循环氧化行为。实验发现Ti-60钛合金基体在800℃氧化严重,氧化层发生了明显剥落。而两种涂层在800℃均能有效地保护Ti-60钛合金基体。在循环氧化过程中Ti-48Al-12Cr涂层增重明显小于Ti-48Al涂层,表现出更好的抗循环氧化能力。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.
