Abstract Scope |
Recent demand of manufacturing Cu-Ni alloys for naval application has become a growing interest. Due to the lack of casting houses, the lead times for Cu-Ni has grown tremendously. Laser Powder Bed Fusion (LPBF) is a rapid solidification process that can create parts of various size and geometries. The influence of LPBF on non-equilibrium microstructure which impact factors such as the corrosion behavior can be different than wrought material. In naval environments where factors such as flow and electrolyte can impact the corrosion behavior, it is important that AM can match or outperform wrought material. Within this study, LPBF processing on Cu-Ni will be explored in relevant quiescent chloride solutions in flowing environments while comparing to wrought material. Difference in the corrosion product film during long term exposure was notable in static environments and incorporating flow while the resultant microstructure, corrosion behavior, and film formation was studied will be detailed. |
