Diagnostics of critical points of the friction coefficient of a multilayer nanomodified antifriction coating by an acoustic emission technique
Source abstract
Abstract
The dynamics of the changing parameter of the acoustic emission (AE) in the course of tests of a multilayer nanomodified antifriction coating are considered. The results of investigating the shape and the spectra of AE pulses in different regions of the experimental curve of the dependence of the friction coefficient on the test time are reported. A method is proposed for establishing the transition points from the steady-state stage to the failure and friction-without-coating stages according to the intensity of the restored AE event stream, the spectral distribution, and the amplitude of the concurrent acoustic emission in the ultrasonic-frequency range.
