Outline of Final Research Achievements

In this work, a new ultrasonic thermometry has been developed to provide an effective temperature profiling for both surface and internal temperature distributions of a rotating object. A laser-ultrasonic technique has been applied to a rotating cylinder being heated and its usefulness for non-contact temperature monitoring has been demonstrated. In addition, two-dimensional temperature determination method by the ultrasonic thermometry is studied. Furthermore, temperature profiles near a friction surface of a sliding solid have successfully measured by the ultrasonic method. Thus, practicability of the developed ultrasonic thermometry for material process monitoring has been demonstrated through the present work.
