Dataset of Optical Profilometry Surface Profiles and SEM of As-Fabricated and Electropolished Surfaces of NiTi Channels Produced by L-PBF Additive Manufacturing

Raw surface profile data from a Zygo Zegage optical profilometer and scanning electron micrographs of the surfaces of NiTi channels fabricated by laser powder-bed fusion (L-PBF) with varying laser power, scan speed, hatch space, scan pattern, channel orientation, and channel diameter. A post-process electropolishing is performed and samples are re-measured. Please refer to the associated research article and Data in Brief below for more information.
