Abstract Scope Laser powder bed fusion additive manufacturing of nickel-based superalloys allows the fabrication of sophisticated geometries, which has opened up the design space for manufacturing products such as heat exchangers or nuclear reactors that require mechanical and chemical reliability at a wide range of temperatures. However, this novel fabrication method inevitably leaves the printed parts with defects such as porosity and rough surfaces, which may deteriorate such reliability. In order to address this problem, the room-temperature corrosion properties of additively manufactured Haynes 282 were characterized as a function of process parameters and scan strategy. Cubic samples were printed by intentionally varying these printing conditions to control the surface roughness and the porosity distribution. We show that these defects in the printed samples, which are quantified by three-dimensional laser scanning and serial sectioning, affect the corrosion rate. Finally, the process is optimized for more sophisticated geometries to increase their corrosion resistance.
