摘要
介绍了利用泄漏瑞利波成像检测陶瓷表面缺陷的方法，并通过实例讨论了采用高频聚焦探头激励泄漏瑞利波的特性以及泄漏瑞利波成像的规律。
The method of leaky Rayleigh wave surface flaw imaging on ceramics using conventional high frequency ultrasonic C-scan system is described.Some testing examples are presented.The characteristics of leaky Rayleigh wave imaging with high frequency focusing transducer are discussed.
