| Résumé | Additive Layer Manufacturing (ALM) presents many design benefits compared to mechanical machining, particularly for complex shape parts. Significant weight and cost savings are achieved because of the production of near-net-shape metallic parts combined with a lower amount of raw materials. However ALM parts suffer from high roughness, worsening the corrosion resistance and the technical endurance. A post-treatment is then necessary to reach mechanical requirements. Electrochemical polishing, usually performed in harmful solutions, appears as a promising technic to reduce surface roughness. The aim of this study is then to develop a sustainable electropolishing process for 316 L ALM parts by using a Deep Eutectic Solvents (DES) as electrolyte. The best electropolishing conditions were first determined on Cast and ALM samples. After electropolishing, both types of sample exhibit bright and smooth aspects, revealing a high roughness reduction. The pitting corrosion resistance of both materials is also enhanced by this process. |
