Tribological Aspects of Slide Friction Diamond Burnishing Process

Even though the foundations of diamond burnishing as a research topic were laid long ago, numerous scientific papers still deal with examining various aspects of the burnishing process today. One such aspect is the investigation of the 3D roughness parameters related to the tribological characteristics of the machined surface, which is detailed in the present study. In this study, the positive properties of slide friction diamond burnishing are presented through the examination of surface quality, which plays a key role in tribological assessment. This study analyzed the surface layer condition of X5CrNi18-10 stainless austenitic chromium-nickel steel test pieces after burnishing. Among the finishing operations, burnishing is an economical and low-environmental impact process. The study includes a description of the technological characteristics of turning and diamond burnishing processes. The main characteristics of the Abbott-Firestone curve are described, and parameter improvement factors are introduced. The experimental results and their evaluations are presented by analyzing the values of the Abbott-Firestone surface curves. The study concludes that the best improvement ratios of <i>S_a</i> (arithmetical mean height), <i>S_q</i> (root mean square height), <i>S_z</i> (maximum height) <i>IS_a</i>, <i>IS_q</i>, and <i>IS_z</i> roughness improvements were achieved when using the parameter combination <i>v</i>₂ = 55.578 m/min, <i>f</i>₂ = 0.050 mm/rev and <i>F</i>₄ = 50 N.
