Abstract

This paper describes some experiments using a deformable dry couplant material attached to piezoelectric probes and used in a send-receive mode. This new couplant has a low acoustic attenuation coefficient and can be 'cold cast' at room temperature and pressure. Therefore even complex shapes of couplant can be manufactured quickly and easily, and it can be cast within ready-made and delicate components. Because the material is highly deformable it can be used on surfaces that are deemed 'too rough' to use the existing rubber couplant alternatives. Experiments have been carried out that use the dry couplant for both normal incidence and angled shear wave inspection. The dry coupled probes have also been used to perform high-temperature ultrasonic measurements up to 370 degreesC.
