Abstract
The effect of surface finishing treatments for inner surfaces of additvely manufactured Inconel 718 specimens were analyzed using X-ray computed tomography (CT). The tube-shaped specimens were built by Laser Powder Bed Fusion (LPBF) at different build orientations and the inner surface characteristics such as roundness, equivalent diameter, 3D curvature distribution and distance to nominal surface as radial roughness for internal channels, both in the primary as built condition and after the subsequent treatment, were evaluated.
