| Abstract Scope |
This study compares the corrosion behavior of two advanced Ni-based alloys, GRX‑810 and HaynesŪ 233, produced via additive manufacturing. GRX‑810, an oxide-dispersed strengthened superalloy, was fabricated using laser powder bed fusion (LPBF), while Haynes 233 was produced using wire arc additive manufacturing (WAAM). Both were tested in 3.5 wt.% NaCl solution. Electrochemical analysis showed superior corrosion resistance for the GRX‑810 as-built sample, with higher corrosion potential and lower current density, while the Haynes 233 wrought condition outperformed its WAAM variants. Surface analysis confirmed Cr₂O₃ as a key passive film component. These findings highlight the influence of microstructure and processing routes on corrosion resistance, supporting the need for post-processing in AM components for aerospace and marine applications. |
