摘　　要：压气机叶片是航空发动机的重要零件之一,直升机飞行、起飞、降落过程中,空气中的固体粒子会随着高速气流进入压气机,对压气机叶片造成冲蚀破坏.在叶片表面镀抗冲蚀防护涂层是保护压气机叶片的有效措施,目前使用最多的抗冲蚀涂层为TiAlN涂层.由于固体粒子的冲蚀速度、冲击角度、粒子粒径等条件不同,对叶片造成的冲蚀破坏也不一样.对压气机叶片进行防护涂层冲蚀破坏模拟可以有效地预测冲蚀位置和冲蚀程度.该文通过建立冲蚀模型,从粒子粒径、冲蚀速度方面对冲蚀结果进行分析.The compressor blade is one of the important parts of aero engine,and the solid particles in the air during the helicopter flight,takeoff and landing will enter the compressor with the high speed air flow,causing erosion damage to the blade of the compressor.The protective coating on the blade surface is an effective measure to protect the compressor blade.Nowadays,the most used erosion resistant coating is TiAlN.Due to the different conditions of erosion velocity,impact angle and particle size of solid particles,the erosion damage caused by blades is different.The erosion damage simulation can effectively predict erosion position and erosion degree.In this paper,an erosion model is established to analyze the corrosion results from particle size and erosion velocity.
