The article describes the deformation-topographic method, developed on the basis of hypsographic and sclerobatic modeling of the microrelief of friction surfaces. Hypsographic modeling allows us to represent the microrelief of roughness of friction surfaces in the form of a normalized coordinate system “relative reference line - relative approximation” tp–ε. Sclerobatic modeling allows to reproduce the diagrams of the distribution of microhardness along the normal to the friction surface of details and in the potential area of their worn layer.
