Outline of Final Research Achievements

Nondestructive inspection of a high temperature structure is required to guarantee its safety. However, there are not any useful sensors for a high-temperature structure. Some of them can’t work at high temperature over 50℃. Another one is too expensive to use it. Therefore, the sensing system which can transmit and receive an ultrasonic wave traveling long distance by using a long waveguide has been studied. It means that an ultrasonic sensor could be driven at atmospheric temperature. We could finally confirm that a guided ultrasonic wave generated by a trial electromagnetic acoustic transducer (EMAT) with Ni-thin sheet on the surface of the pipe can travel more than 10m using a thin bar with a 2mm - diameter as a wave guide. Next, we tried to transmit and receive a guided wave into a pipe using the developed system. It is indicated that a special shaped waveguide on the pipe is useful.
