| 摘 要： | The NiCrAIY＋ZrO2 thermal barrier coating was prepared on the surface of TiAI alloy by plasma spraying technique. The microstructure and phase structure were analyzed using scanning electron microscopy （SEM） and X-ray diffractometry （XRD）. The high temperature oxidation resistance of the plasma sprayed samples at 850℃ was investigated. The results show that the bonding between thermal barrier coating and substrate is very good. Surface hardness of TiAI alloy is improved too, The microhardness of the coating surface is about HV 900 after the oxidation test at 850 ℃. The oxidation resistance of the samples is improved remarkably.
