This article describes the results of research of the acoustic emission of friction pairs in the process of their operation. The dependences of the parameters of acoustic emission that correspond to the alteration of the energy dissipation mechanism of the superficial layers of friction pairs at the transition to "quasiwearless" mode of their operation are obtained.

The theoretical research of the influence of temperature on the parameters of the alteration of acoustic emission signals from plastic deformation is considered. It is shown that increasing temperatures cause an increase in the amplitude of acoustic emission signals in an area of low temperatures and a decrease in an area of high temperatures. At the same time, there is an intermediate area of temperatures in which the amplitude of acoustic emission signals remains constant when temperature is increased. As shown in the article, this fact is connected with the alteration of the process of plastic deformation. [ABSTRACT FROM AUTHOR]

The perspectives of application of using RVS technique for repairing and prophylactic of hydraulic systems' units, particularly axial-piston machines are considered. Physical background of revitalization processes, which took place on the friction surfaces during drifting of cermets coating (CC) are uncovered. The results were received from numerous investigations. [ABSTRACT FROM AUTHOR]
