Abstract

The results of experimental studies of acoustic emission signal, which are registered in the friction surfaces of specimens with coating is conducted. Was shown that with increasing axial load on the friction pair occurs the growth of the average power of the resulting acoustic emission signal and its variance and standard deviation. It was determined that growth of this parameters by nonlinear law.
