Investigating the impact of post-processing techniques on surface morphology and wettability of Inconel 718 components fabricated via selective laser melting

Original language description

This study investigates the impact of three post-processing methods—sandblasting, centrifugal tumbling, and electrolytic polishing—on the surface characteristics and wettability of SLM-printed Inconel 718. Surface roughness parameters, including arithmetic mean height (Sa), maximum peak height (Sp), maximum valley height (Sv), maximum height (Sz), root mean square roughness (Sq), surface kurtosis (Sku), and surface skewness (Ssk), were analyzed to assess the effectiveness of each treatment. The results revealed notable reductions in surface roughness: sandblasting reduced roughness by 45%, centrifugal tumbling achieved a 67% reduction, and electrolytic polishing provided a 47% improvement when applied individually. Remarkably, when all three methods were combined, the overall surface roughness decreased by 90% compared to the as-printed state. Surface topography analysis identified defects such as micropores, cracks, and dimples on the treated surfaces. Wettability assessments demonstrated enhanced hydrophilicity, with the contact angle decreasing from 82° to 35° after post-processing. This study highlights the importance of post-processing in improving the surface finish and functional characteristics of Inconel 718 produced through SLM, thereby expanding its potential for various industrial uses. © 2025 The Authors
