The possibilities of creating a plateau-like surface using turning followed by axial roller burnishing are presented. The influence of the parameters of symmetric triangular roughness after turning and the burnishing speed on selected surface profile parameters was investigated. Regression equations were derived, capturing the influence of the apex angle of the roughness, the spacing of the roughness valleys after turning, and the burnishing speed on the surface profile after roller burnishing.Surface treatment is the deliberate application of various methods to material surfaces (semi-finished products) in order to create a surface layer that, under specific technical and economic conditions, meets operational requirements [3]. The state of the surface layer has a decisive influence on wear processes, and thus on the durability and reliability of vehicles (devices). The following properties of the surface layer have the greatest impact on the functional quality of a product: geometric structure of the surface, type and structure of the material zones, hardening (strengthening) of the surface layer, residual stresses of the surface layer, and the size and distribution of material defects. Parts with a plateau-like profile have many advantages, such as: practically no break-in period, and much greater durability and wear resistance compared to parts made using traditional methods. (…)
