摘要：
We study the joint dynamics of changes in the parameters of acoustic emission (AE) and in the friction coefficient during TRB friction machine testing of flat steel 12Kh2N4ASh specimens, including those with Ti + Al + N ion-plasma vacuum sputtering. The results of studying the shape of the curve of the reconstructed values of AE-event stream intensity in different parts of the experimental curves of the dependence of friction coefficient on test time are presented. A significant correlation was discovered between the friction coefficient and the reconstructed AE-event stream intensity. Methods are proposed for evaluating the friction coefficient and the time of the run-in stage end based on the reconstructed AE-event stream.
