Feasibility study on ultrasonic In-situ measurement of friction surface temperature

The feasibility of ultrasonic in-situ measurement of friction surface temperature has been examined. The ultrasonic thermometry that is a method providing nondestructive temperature measurements by ultrasound is applied to temperature measurements of a friction surface at which temperature rise occu...
