Abstract

This paper describes the propagation characteristics of ultrasonic waves in glass flake coatings. Specimens with glass flake contents from 0 to 35 wt% were prepared and subjected to ultrasonic contact and immersion tests, and the dependence of the bottom echo height on the glass flake content was in-vestigated. It was found that at a test frequency of 5 MHz, the bottom echo height increased with decreasing glass flake content. In contrast, at a fre-quency of 2 MHz, the bottom echo height was independent of the glass flake content. In addition, the frequency of the reflected ultrasound was shifted downwards by about 1 MHz, regardless of the glass flake content or the test frequency．
