Abstract

The high information content of the vibroacoustic signal in the frequency range of 10‒16 kHz to the change in the state of the surface layer of the ceramic sample during frictional interaction with the steel disk was established. The results obtained indicate the possibility of using vibration diagnostics systems for monitoring the state of ceramic parts during operation and fi tests.

Keywords

ceramics, vibroacoustic (VA) signal, surface layer (SL), root mean square value (RMS) of vibration acceleration, frictional interaction (FI), wear, destruction,
