摘　　要：利用电弧离子镀技术在航空发动机压气机用1Cr11Ni2W2MoV在不锈钢上沉积了(Ti,Al)N梯度涂层.X射线衍射的结果表明涂层为B1型(NaCl)单相结构,具有(220)择优取向.扫描电镜观察表明,涂层均匀致密,与基体结合良好.电子探针元素线分析和截面面分布表明,所制备的涂层是内层富TiN、外层富(Ti,Al)N的梯度涂层.试验结果表明,(Ti,Al)N梯度涂层具有良好的耐磨性等机械性能.Gradient （Ti, Al） N coating was deposited on 1Cr11Ni2W2MoV stainless steel for aero-engine compressor blades by arc ion plating. The XRD results show that the gradient coating has a B1 （NaCl） structure with （220） preferred orientation. The coating was uniform and dense. The elemental gradient distributions of Ti and Al were confirmed by electron probe microanalysis. The surface and cross-sectional morphologies of the coating were investigated by scanning electron microscopy. The experiments indicate that the gradient （Ti, Al） N coating can obviously enhance the wear resistance and other mechanical properties.
