Abstract

To evaluate the adhesive property of chemical vapor deposit (CVD) diamond coating layer, back-scattered Rayleigh surface wave method is applied. However, the interpretation of the back-scattered Rayleigh surface signal is not easy. To take care of such a difficulty, we propose the time trace angular scan (TTAS) method and the frequency spectrum angular scan (FSAS) method to help the interpretation of the back-scattered Rayleigh surface waves from the CVD diamond coating layer. Using the proposed signal interpretation tools, we evaluate the adhesive property of CVD diamond coating layer. In this paper, the concept of the TTAS and the FSAS methods and the initial experimental results are presented to demonstrate the effectiveness of the proposed approach.
