Dynamics simulation of burnishing of a thin steel layer beneath an indenter applied with a constant force and then moving with a constant velocity was performed by the finite element method in the plane strain approximation. The indenter was modeled by a perfectly rigid body, and the steel was modeled by an elastoplastic body with isotropic hardening according to an experimentally defined law. The regularities of changes in the stressstrain state of the material near the treated surface were studied and mechanisms of the formation of a nanostructured layer were disclosed. The effect of the friction coefficient and the burnishing force on the height of a bulge of edged material was analyzed. The results of studies agree well with experimental data.

“…A number of authors [1][2][3][4][5][6][7] have studied finishing and hardening burnishing without taking into consideration the possibility of forming nanocrystalline structures. To promote burnishing the papers [8][9][10][11][12][13][14][15][16] bring into the foreground a finishing technique for forming a nanocrystalline structure in the surface layer, which puts to use the method of severe plastic shear deformation (SPD), named nanostructuring burnishing (NSB).…”

The article probes into a relationship of the shear strain intensity and the shear strain rate in the surface layer and the sliding velocity of a spherical indentor and its loading repetition factor. It brings forward an experimental procedure to evaluate the shear strain intensity and rate by analyzing the geometrical parameters of the bulge of plastically edged metal and the thickness of the shifted layer relative to different sliding velocities and feed rates.

“…The surfaces treated by dynamic burnishing are characterised by high smoothness and high material bearing, which is related to the shape of micro-irregularities, which is more "streamlined" [8,10]. "Punching" the machined traces on the processed surface allows the formation of potential "reservoirs" that can accumulate lubricants in their space, thereby contribute to increasing the wear resistance of these surfaces [5,6].…”

The paper presents the research results of roughness and surface topography of the C45 non-alloy steel after centrifugal burnishing and perpendicular peening. The assessment of the geometric structure of the tested steel surface included the parameters: amplitude: Ra, horizontal: RSm, height: Rz, Rp and Rv, and Abbott-Firestone curve: Rpk, Rk and Rvk. Perpendicular shot peening was performed on a special position, while centrifugal burnishing on a 3-axis milling centre XH712G. The variable parameters during shot peening included the impact energy E z = 40 ÷ 220 mJ and the distance between traces x s = 0,15 ÷ 0,5 mm. The machining conditions of centrifugal burnishing were selected in such a way that the perpendicular component of the impact energy, longitudinal feed and transverse travel correspond to the variable parameters of perpendicular shot peening. The T800 RC 120-140 device of the Hommel-Etamic company with software was used for measuring surface roughness and topography.
