“…It is known that the main threats to surface integrity come from the plastic deformation of the workpiece during the machining process, and the plastic deformation could change if we modify any turning parameter, such as feed rate [18,19]. In this sense, Fig.…”

This study investigates the corrosion potential of ASTM A-36 steel after slide burnishing using different applied forces. Turned samples of ASTM A-36 steel were subjected to slide burnishing surface treatment. The burnishing process was carried out with forces of 150 N, 300 N, and 450 N, at a travel speed of 100 mm/min. The effects of burnishing on the chemical composition of the material were analyzed using Grazing Incidence X-ray Diffraction and X-ray photoelectron spectroscopy, which indicated no changes in the chemical composition of the material. Corrosion potential measurements were performed using the Tafel test. The results showed that as the burnishing force increased, the corrosion potential shifted to lower values. Additionally, roughness analysis suggested that the change in corrosion potential was attributed to plastic deformation caused by the burnishing process. The increased mechanical work exerted on the material during burnishing may be the underlying reason for the observed shift towards lower corrosion potentials with higher applied forces.

“…Another result is the improvement of areal surface roughness by subsequent burnishing is proportional to the surface roughness generated by previous turning, which is in consistence with other literatures. 36,37 This reason is essentially determined by the surface residue induced by turning with different feeds. However, there is less difference in the surface roughness values after UWB treatment for turned surfaces obtained by any feeds.…”

Improving the surface integrity of laser cladded layer via burnishing is an important research topic in remanufacturing field. However, the initial surface roughness condition induced by mechanical machining generates great influence on the strengthening mechanism of subsequent burnishing. In this study, the effects of ultrasonic-assisted burnishing (UB) and ultrasonic-assisted warm burnishing (UWB) on the surface integrity of laser cladded layer were analyzed when treated on different surface conditions obtained by turning with different feed parameters. The results indicated that both the UB and UWB treatments would cause great improvements in microhardness, surface roughness including height and functional parameters, and residual stress of the laser cladded layer when compared to those by turning. First, the severe plastic deformation in UB and UWB treatments counteracted the thermal softening effect in turning process, so that the machined surface could maintain high hardness. Second, UB treatment reduced the roughness by 70% compared with turning, while the surface roughness after UWB treatment was even 30% lower than that obtained by UB. Third, the tensile residual stress shifted to deep compressive state by both UB and UWB treatments, though the thermal load in UWB generated a negative effect on generating compressive residual stress. According to the surface integrity evaluation results by radar diagrams, turning with feed f = 0.2 mm/r and UWB is preferred in machining of the laser cladded layer for enhanced surface integrity. On the basis of this research, it is expected to achieve the purpose of high-efficiency and high-quality cutting of the laser cladded layer.

“…The complex surface topography was simplified to ideal sinusoidal micro-notches, and the maximum error between the experimental and theoretical results was only 2 %. Zhang et al (2010) simplified the surface roughness as semi-elliptical micro-notches and proposed a relationship between the surface roughness and fatigue life. Liao et al (2015) simplified the surface topography as semielliptical micro-notches and established a 3D FE model of the flat surface topography to determine the influence of the micro-notch parameters on the SCF.…”

Abstract. Surface topography is an important parameter for evaluating the quality of surface machining, and the stress concentrations produced at notches can have a profound effect on the fatigue life of notched components. The stress concentration factor (SCF, Kt) and relative stress gradient (RSG, χ) are important parameters used to quantitatively characterize stress concentration. In this study, a finite-element (FE) method was used to evaluate the surface SCF and RSG and determine the effect of microscopic surface topography on machined surfaces. An FE simulation of the static tension test of V-notched round-bar specimens was performed, and the stress due to the local surface topography was investigated. The FE method was used to analyze the stress concentration of round-bar specimens with Kt=1, and the reliability of the results was verified using a perturbation method. The FE method was used to calculate the surface SCF and RSG with high accuracy. The surface SCF and RSG values increased with the surface roughness, and the local maximum values of the surface SCF and RSG were at the bottom of the local topography. Therefore, the SCF and RSG could be estimated based on a linear relationship involving average roughness.
