摘要/Abstract

摘要： 涂层脱粘常采用超声C扫描成像技术进行定量检测，但涂层厚度过小或探头频率较低均可使顺序界面回波混叠而无法直接采用C扫描方法有效表征脱粘。基于声压反射系数幅度谱特征，通过分析幅度谱极值与谐振频率随粘结界面反射系数的变化规律，提取幅值波动范围、谐振频率阶数两个幅度谱特征重构C扫描图像。采用该方法对厚度0.3 mm环氧树脂基涂层/5 mm铝板构成的含10×10 mm界面脱粘试样进行定量表征，重构C扫描图像定量的脱粘尺寸相对误差分别为4.9%和1.0%。该技术可以克服传统超声C扫描成像的局限性，提高涂层脱粘尺寸定量精度。

Abstract: Conventional ultrasonic C-scan imaging is suitable for quantitatively determining the debonding of engineering components. However, this method using low-frequency transducer fails to detect the thin coatings due to the overlap of the echoes from the sequential coating surfaces. A new ultrasonic C-scan imaging method based on ultrasonic reflection coefficient amplitude spectrum (URCAS) is proposed for determining the coating debonding. The URCAS extremum and resonant frequency dependence of the reflection coefficient at the debonding interface between coating and substrate is investigated. Two URCAS characters:amplitude fluctuation △R and resonant frequency order n are extracted to reconstruct the C-scan images. An ultrasonic experiment is conducted on an epoxy coating specimen with the thickness of 0.3 mm. A debonding with a size of 10 mm×10 mm is embedded between the epoxy and aluminum substrate. The measured relative error of the debonding area through the C-scan images reconstructed by △R and n are 4.9% and 1.0%, respectively. The proposed ultrasonic method is valid for nondestructive characterization of the debonding of the coatings.
