“…The beater with a ball (8), which is an interchangeable element, moves while operating in the ball guides (7). The table, on which the workpiece is attached, performs a feed movement, and the speed of this movement may be controlled with a guide screw (11) and the gear (12).…”

“…The change in the concentration of the crystalline structure defects is also the effect of burnishing machining, resulting in compressive stresses constituted in the surface layer [25]. Changing the state of residual stresses results in an increase in fatigue durability [11,23]. Burnishing is successfully used not only to improve the properties of the surface layer, but it is also used to round the edges of the workpiece [15].…”

This article presents the research results of roughness and topography of the surface of Inconel 718 nickel alloy after shot peening. The evaluation of stereometric properties of the surface layer of the examined material was performed based on the amplitude, height and Abbott-Firestone curve parameters. The shot peening was carried out on the impulse shot peening stand. The impact energy E z , distance between the traces x s and the ball diameter d k were changed in the range: E z = 60 ÷ 240 mJ, x s = 0,15 ÷ 0,5 mm, d k = 3,95 ÷ 12,45 mm. The T8000 RC 120-140 device of the Hommel-Etamic company, along with the software, was used for measuring the surface roughness and for determining the material bearing curve. As a result of the machining, the surface roughness was reduced and the selected functional parameters were improved.

“…The present work performed soaking, quenching, and tempering on 51CrV4 steel since this kind of heat treatment is a conventional manufacturing route to improve its mechanical properties. Previous researchers have studied the effects of various parameters during heat treatment on the microstructure and mechanical properties of 51CrV4 steels [3,[19][20][21]. However, very few researches have focused on the detailed quenching conditions such as the oil-bath temperature and the out-of-oil workpiece temperature, which is essential to obtain the required strength and ductility.…”

51CrV4 steel is extensively used in large-size damping springs for trains and vehicles. Quenching conditions play an important role in performance enhancement. The present work investigated the effects of various oil-bath temperatures and out-of-oil temperatures on the microstructure and the mechanical properties of this steel. The morphological examination focused on both the quenched martensite and the tempered troostite. Tensile and hardness tests were carried out to evaluate the mechanical properties. The results showed that a coarsening of the martensite occurred at a high oil-bath temperature. In addition, the size and fraction of bainite islands also increased with the increase of oil-bath temperature. In contrast, the carbide size and the intercarbide spacing both increased with the increase of oil-bath temperature. Thus, the tensile strength and the hardness both decreased with increasing oil-bath temperature in accordance with the Hall-Petch relationship. Correspondingly, the ductility increased as the oil-bath temperature increased. At a relatively high out-of-oil temperature, the martensite underwent an auto-tempering process, which led to the precipitation of many tiny carbide particles in the as-quenched martensite laths. This auto-tempering effect enhanced the width of large-sized carbides and reduced their length in the final microstructure. The intercarbide spacings increased with increasing out-of-oil temperature. As the oil-bath temperature increased, the tensile strength and hardness decreased, and the ductility increased. The fracture morphology was examined to explain the results of mechanical properties.

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.
