Sensitivity of Vibroacoustic Signals to the Variations of State of the Surface Layer of Ceramics in Friction

We establish high information content of vibroacoustic signals within the frequency range 10–16 kHz reflecting the changes in the state of the surface layer of a ceramic sample in the course of friction interaction with a steel disk. The accumulated results indicate the possibility of application of...

Zusammenfassung:We establish high information content of vibroacoustic signals within the frequency range 10–16 kHz reflecting the changes in the state of the surface layer of a ceramic sample in the course of friction interaction with a steel disk. The accumulated results indicate the possibility of application of vibration diagnostics systems for the purposes of monitoring the state of ceramic parts in the course of operation and full-scale testing.
