    A low frequency ultrasonic Rayleigh like wave method suitable for characterizing shear and longitudinal wave velocities, thickness and density of ultra thin coating layer of coating/substrate laminate composite is presented. By “ultra thin”, we mean that the thickness of the plate is only a fraction of the ultrasound wavelength so that the echoes from the front and back surfaces cannot be separated in the time domain. The dispersion curve of the ultrasonic Rayleigh like wave is obtained by employing the frequency domain analysis of the leaky ultrasonic Rayleigh like wave. In conjunction with the method of least square, the secant algorithm is used to estimate the parameters of the coating. Te reasons for evaluation error of the parameters and the sensitivity of the method for different parameters are analyzed. Using a pair of broadband longitudinal wave with 2MHz center frequency transducers, we have accurately characterized the parameters of silver coating, with the thickness of 26μm, of the silver/glass composite.

    本文提出低频超声类瑞利波定征方法来估计覆层/基层层状复合结构超薄覆层的纵波声速、横波声速、厚度和密度等参数。这里“超薄”的概念是指覆层厚度h远小于覆层中的声波波长λ,导致在时域上覆层前后界面的各次回波信号相互混迭。文章采用水楔耦合方式,利用超声漏类瑞利波频域分析方法获取层状复合结构超声类瑞利波色散曲线,提出以色散特性为基础的低频超声类瑞利波覆层定征方法和在最小二乘意义下以色散曲线为基础的反向算法对覆层进行了参数估计。文中分析了影响估计准确性的各种因素,研究了低频超声类瑞利波定征方法对覆层各参数的灵敏度及其在误差传递中的意义。实验结果证实,对于银箔/玻璃层状复合结构,该方法能够准确估计厚度小到26μm银箔覆层的声学参数。
