Description

Ultrasonic immersion methods have been used for nondestructive evaluation of material properties as well as for B- or C-scan imaging of internal microstructure and/or defects. However, the direct application of this method is difficult for dissolving or hygroscopic materials as well as rusting metals. Thin waterproof coating on such materials enables us to apply immersion methods for those materials and it is also effective for reducing reflection at the water/material interface, if the coating has an appropriate acoustic impedance.
