Microstructure, mechanical, and corrosion resistance of copper nickel alloy fabricated by wire-arc additive manufacturing

Copper–nickel alloys were obtained by wire-arc additive manufacturing (WAAM) and thoroughly analyzed spectro- and microscopically. Mechanical (microhardness, tensile, and impact strength) and corrosion resistance properties were also tested. The Cu–Ni alloy samples were very uniform, with minimum de...

Summary:Copper–nickel alloys were obtained by wire-arc additive manufacturing (WAAM) and thoroughly analyzed spectro- and microscopically. Mechanical (microhardness, tensile, and impact strength) and corrosion resistance properties were also tested. The Cu–Ni alloy samples were very uniform, with minimum defects, and contained large crystals and single-phase solid solution. The microhardness distribution in the transverse and longitudinal directions was uniform. The regular and breakdown corrosion potentials of the Cu–Ni alloy fabricated by WAAM were equal to − 211 and 17 mV, respectively, while the resistance was 7.6 Ω cm 2 . The Cu–Ni alloys produced by WAAM are excellent compared to conventionally manufactured. Graphical abstract
