The tribological effects of diamond burnishing are investigated on EN AW 2011 aluminium alloy cylindrical surfaces. In engineering practice, the tribological behaviour of machined parts is often characterized using functional surface roughness parameters such as the Sk (core roughness depth), Spk (reduced peak height), and Svk (reduced valley depth) 3D roughness parameters. In the present study, the influence of various burnishing parameter settings is evaluated comprehensively through both their quantitative roughness values and the corresponding Abbott-Firestone material ratio curves. This combined approach enables a deeper understanding of how the burnishing process modifies the surface topography and, consequently, the tribological performance of the material under operational conditions.
