Additive manufacturing (AM) by Laser powder bed fusion (LPBF) has gained significant research attention to fabricate complex 3D Inconel alloy components for jet engines. The strategic advantages of LPBF based AM to fabricate jet components for aerospace applications are well reported. The jet components are exposed to high degree of vibration during the jet operation in variable aqueous environment. The combined vibration and the aqueous environment create a tribological condition which can accelerate the failure mechanism. Therefore, it is critical to understand the tribocorrosion behavior of the Inconel alloy. In the present work, tribocorrosion behavior of the LPBF fabricated Inconel 718 in the 3.5% NaCl aqueous solution is presented. The LPBF fabricated samples are analyzed to determine the impact of porosity, generated as a result of LPBF, on the trobocorrosion behavior of AM Inconel 718. This study provides an insight into a critical aspect of the AM Inconel components.
