摘　　要：智能涂层由与结构基体紧密结合的驱动层、探测信息的传感层及相应的保护层构成,对智能涂层与基体产生裂纹的部位、时间一致,裂纹扩展的过程一致或具有线性相关性进行了随附损伤分析。进一步利用弹性力学分析法对以金属为基体的智能涂层应力状况进行探讨,为后续智能涂层的疲劳裂纹萌生及扩展行为提供理论依据。Intelligent coating is composed of driven layer by closely combining to substrate and sensing layer of detection information and corresponding protective layer. Intelligent coating and substrate crack parts, at the same time, crack propagation process is consistent or with linear correlation in the attached damage. Further, by using elastic mechanics analysis method of the intelligent coating to metal substrate stress conditions were discussed, which can provide subsequent intelligent coating of fatigue crack initiation and propagation behavior for theoretical basis.
