| Abstract Scope |
Manufactured parts by laser powder bed fusion (L-PBF) with complex geometries, such as notched ones, have high surface anomalies due to the presence of overhangs which can detrimentally affect the mechanical properties and fatigue behavior. Therefore, applying post-processing can play a crucial role in addressing these issues leading to improved mechanical properties. In this study, the effects of different chemical surface post-treatments of chemical polishing (CP), chemical brightening (CB), and electro-chemical polishing (ECP) as well as T6 heat treatment (HT) on the surface texture, microstructure, and rotating bending fatigue behavior U-notched L-PBF AlSi10Mg specimens were investigated comprehensively through various experiments. The obtained results indicated that chemical treatment was very influential on surface texture modification of the very narrow notched parts, resulting in considerable fatigue life improvement. |
