“…Swirad and Pawlus found that ball burnishing caused reductions in wear and friction under dry sliding compared to milled samples [6]. Ball burnishing led to a decrease in the coefficient of friction in lubricated sliding [15], this effect was related to the improvement of surface quality of steel samples.…”

Experiments were conducted under a dry gross fretting regime. Steel discs were put in contact with ceramic balls. Before tribological tests, discs were subjected to ball burnishing with different pressures. Due to ball burnishing, a decrease in surface amplitude and an increase in microhardness occurred. Ball burnishing caused decreases in the friction force and volumetric wear of up to 45% in comparison to sliding pairs containing milled discs. The friction force and volumetric wear were higher for a higher roughness of disc.

“…The plastic deformation of the M1 surface was likely easier than that of the M2 surface. The possibility of obtaining a smoother surface due to burnishing is important because in [24,34,37], the lowest roughness height led to the smallest friction and wear.…”

The description of the areal texture of the surface is more comprehensive than that of roughness profiles. Ball burnishing led to an improvement in surface quality. In this work, the changes in areal surface textures due to ball burnishing were studied. Three surfaces of steel, two after milling and one after grinding, were subjected to ball burnishing. In the burnishing process, the burnishing pressure and width were variable parameters. Surface topographies before and after burnishing were measured using a white light interferometer. Ball burnishing was found to lead to a decrease in surface amplitude. The highest relative reduction was 94%. The changes in roughness height were greater with a higher amplitude of the surface texture before burnishing. The hybrid parameters also decreased as a result of ball burnishing. The characteristics of changes in spatial parameters mainly depended on the surface texture before burnishing.

“…An overlap is created between the working surface of the tool and the surface of the workpiece to be formed, and thus the tensile residual stress in the post-cutting surface zone is converted to a favourable compressive residual stress. This is one of the most advantageous properties of this process as, in addition to hardening, it also contributes to increasing the lifetime of the machine element, since it improves the resistance of the material to fatigue [14][15][16][17][18][19][20][21][22]. This paper deals with the examination of these two characteristics: surface micro-hardness and residual stress.…”

The purpose of this paper is to present a comprehensive study of the stress state and hardening characteristics of low-alloyed aluminium cylindrical specimens subjected to the diamond burnishing process. Diamond burnishing has a surface hardening effect on structural steels. In the present study, our aim was to check whether this surface hardening effect is also observed for other (less hard) material grades, such as low-alloy aluminium. We also aimed to determine the technological parameters at which the greatest relative increase in hardness can be achieved by burnishing. In addition to the hardness test, the changes in the residual stress state due to burnishing were also analysed. Both hardness and residual stress tests were performed in two variants. Of the 4 technological parameters (burnishing speed, feed, burnishing force and number of passes), the burnishing speed was set to constant for one variant and number of passes was set to constant at the other variant, while two levels were chosen for the other parameters. A special formula was developed to determine the relative improvement in residual stress and hardness. Our experiments were performed using a full factorial experimental design. The results show that diamond burnishing has surface hardening effect and increases of residual stress on an aluminium alloy when applying adequate technological parameters.
