Surface Roughness Improvement by Sliding Friction Burnishing of Parts Produced by Selective Laser Melting of Ti6Al4V Titanium Alloy

Selective laser melting is a frequently used, powder bed fusion additive manufacturing technology for producing metallic parts. However, appropriate surface quality cannot be achieved, so post-processing often necessary. Subsequent machining of surfaces serves multiple objectives such as improvement dimensional accuracy, changing roughness and modification the residual stress state higher hardness. Beyond its several advantageous properties, Ti6Al4V material has, weaknesses, low tribological behavior wear resistance. Sliding friction burnishing conventional chipless coolant-free environmentally conscious that simultaneously decreasing increasing Until now, there has been research gap regarding diamond selective melted In this study, we investigated how parts can modified via sliding burnishing. 2D 3D characteristics were measured by chromatic measuring device. Indices defined studied function parameters. Optimal parameters power—P = 280 W scanning speed u 1200 mm/s—for effective are proposed.
