| Abstract Scope |
The restricted availability of casting facilities has significantly impacted the production and delivery schedules for Cu-Ni alloys, which are essential for numerous applications. To address this challenge, it is imperative to explore alternative manufacturing methodologies. Wire arc additive manufacturing (WAAM) presents a promising solution by enabling the rapid production of complex Cu-Ni alloy components on a large scale, thanks to its high material deposition rate and low production costs. In this study we explore the corrosion behavior of WAAM-produced Cu-30Ni alloy in 0.6 M NaCl as a surrogate for marine environments. A suite of electrochemical techniques alongside multi-scale characterization methods were employed to understand the evolution of corrosion resistance as functions of heat treatment and exposure time. The results suggest that processing conditions and post-build heat treatments significantly influence the overall corrosion performance of the alloy. |
