Abstract Scope |
Additively manufactured components have a high degree of surface roughness inherent to the nature of the process. AM components find their applications in aerospace, defence etc., made from Inconel 718. Post-processing is necessary to improve the functionality of such high-value components to bring down surface roughness within the permissible limits.
Various techniques are available to achieve the required surface finish, such as electro-polishing, buffing, and lapping. However, these techniques require synthetic additives and lubricants, posing a threat to the environment and increasing the overall operational cost. Natural additives can offer an alternative to ease the process and reduce the operation cost.
In this work, natural additives (citric acid from lemon) and natural abrasives (rock-stone) have been used to enhance the surface finish of AM blocks. A 40% reduction in the surface roughness (Sa) has been obtained using citric acid over Inconel 718, indicating a step towards realizing green surface manufacturing. |
