As is known, many performance properties of the friction surface areas, such as contour area of the contact, oil carrying capacity, abrasive ability, friction coefficient, conformability, etc., are determined by the parts microgeometry of the machine friction couples often expressed by the profile elements height and width. However, the traditional roughness evaluation method using diamond probe surface scanning gives the highquality profilogram and the data on many parameters of surface microgeometry, while it still has a number of disadvantages, including high costs of profilometers, relatively time-consuming measurements, sophistication of maintenance, high sensitivity to various contaminants on the surface. The article presents description of elaborated methods and instruments for acoustic emission quality testers of friction surface areas. The main advantages and spheres of application for the diagnostic system promptly identifying the defects on the heavy-duty surfaces of the machine parts are given and the advantages of multiagent data collection system are presented.
