“…The response surfaces illustrating the variation of the responses studied (Hv, Rm, W, e) as a function of burnishing parameters (Py, i) (Fig 8). The graphics show that the effect of the number of tool passes "i"on the surface hardness "Hv" and rupture strength "Rm" are more significant compared to burnishing force "py", where it clearly appears that "Hv" is all more improved, as the number of tool passes increases (i = 3) in particular for low loads [40]; which reaches a value of 243.06 Hv (Fig 8a). Likewise, the rupture strength "Rm" increases considerably with the increase in the number of tool passes (Fig.…”

Often, surface mechanical treatments (SMT) or heat (quenching, tempering) are used to improve the surface condition and mechanical characteristics such as impact resistance and tensile strength. Hence the objective of this experimental work, where ball burnishing (BB) as well as quenching and tempering were applied on S355 JR steel specimens in order to evaluate the surface hardness "Hv", the rupture strength "Rm", the energy absorbed "W" during the impact test and the work-hardened thickness "e" after the burnishing operation. Factorial designs were used for the tests organization and mathematical models were established for the prediction of "Hv", "Rm", "W" and "e" in function on treatment parameters considered: number of tool passes ( i) and the pressure force (Py). The results show that the surface hardness increases by 30.46%. The high levels of "Py" and "i" were allowed to improve "Rm" by 30.8% as well as an increase in tenacity of only 3.6%. Increasing the force to 20kgf promotes mixed rupture under the effect of impact to shock. The quenching and tempering improve the resistance "Rm" by 183% and 119% respectively, while the effect of burnishing was limited to a rate of increase of this property of 28% compared to machining.

Surface quality of product plays a vital role to take competitive advantages in present market condition. Surface finish is an important service characteristic of a product, such as corrosion resistance, wears resistance and fatigue life. Burnishing is one of the cost-effective surface finishing processes which is utilized in the aerospace, biomedical and automotive industries to increase the component's reliability and performance. Burnishing produces a very smooth surface finish by pressing a ball or roller against the machined workpiece. In addition, due to the surface plastic deformation caused by the movement of the hardened ball or roller, the mechanical and physical properties such as residual stresses, surface finish, hardness, roundness, diameter reduction, wearing, etc. could also be improved. These positive improvements are dependent on burnishing process parameters such as speed, feed rate, burnishing force, ball diameter, strategy and a number of revolutions, etc. Diverse studies have been focused on the theoretical, numerical and experimental stages of this process in order to analyze and predict the influence of process parameters. The most important purpose of this work is to present the reviewed state of the art of various studies of the burnishing process, providing a general overview of the developing research of the process. The studied materials and the main parameters are discussed, stating the value ranges preferred by different researchers. In addition, other important parameters are discussed such as: kind of tool, geometry of the working piece, design of experiments, kind of lubricant and effect of the process on the surface integrity of the workpiece.

“…Zhuang and wicks [17] worked on aircraft engine components and conducted a three-dimensional study of the complex pressure generated due to cyclic plastic deformation. Salahshoor and Guo [18] worked on a Ti6Al4V workpiece that considered the ceramic ball as a ball material and developed a three-dimensional analysis for compressive stresses and surface roughness. Mounira Bourebiaa in [19] mentions that burnishing imparts a superficial hardness improvement to the surface.…”

Burnishing is a cold working technique used as a surface enrichment to meet the desired surface properties of the workpiece. It improves the visual properties, dimensional tolerances, fatigue strength, surface roughness, and hardness of the work material by applying appropriate pressure through a complex ball burnishing tool to cause plastic deformation. In the current work, the mathematical modeling of the burnishing process was carried out to predict surface roughness by considering the process parameters such as contact radius, penetration depth, and elastic rebound. Further, a customized tungsten carbide (W.C.) insert having a hardness of 80 HRC was developed for the burnishing operation. The micro-hardness of the resulting burnished surface improved from 44 to 48 HRC. The surface quality of the tungsten carbide insert improved by up to 17.1 nm through polishing. Several experiments were performed by selecting appropriate process parameters using developed model feedback. The surface quality of the workpiece improved by up to 45 nm, which resulted in automatic improvements in fatigue strength up to seven times that of the virgin material. The results predicted from the mathematical model were in good agreement (less than 5% deviation) with the experimental results. This study helps to understand the surface formation mechanism in the burnishing process in more detail. Additionally, the achieved results show a significant improvement in the surface finish (~95%), indicating the potential of the burnishing process and how fast and cost-effective it is. The novelty of this paper lies in the improvement in surface roughness and the validation of our mathematical model results with the experimental results.
