Abstract Scope |
Additive manufacturing (AM) of metal components has advanced in terms of Technology Readiness Level, thanks to the development of process-structure-property (PSP) maps and refined processing methods. Directed energy deposition technologies such as laser engineered net shaping (LENS) and wire arc AM (WAAM) have shown great promise for components in high-temperature environments such as those seen in the energy and aerospace industries. The surface roughness of AM parts is a significant process-induced defect that can affect part quality, as well as thermal and hydraulic performance—especially important in components such as printed circuit heat exchangers. This parametric study of surface roughness looks at the fabrication of 316L stainless steel and Inconel 718 single-track clads using LENS and WAAM. Surface roughness is measured using laser-optical advanced microscopy, and the initial experimental results for the arithmetic mean surface roughness and PSP maps are presented. |
