The paper concludes the results of computing the parameters of contact interaction of rough surfaces of friction. The microgeometry of the surfaces was simulated using Gaussian random fields, the statistic characteristics of which were determined by the results of profilogram processing. The force of contact interaction of elastic surfaces was calculated by solving the Hertz problem of point contacts. The dependences of the contact area, coefficients, the volume of the contacting material, and the surface interaction force on the generalized parameter of roughness for pairs of friction steelsteel and steelbronze are cited. The results of a computational study of the contact surface interaction made it possible to estimate the limits of friction regimes depending on the surface microgeometry and specific load on supportingsealing assemblies.
