The laser powder bed fused (LPBFed) stainless steels showed anomalous and localized corrosion behavior in the nuclear reactor high-temperature water compared to their wrought counterparts, which affects performance during plant operation. In this study, advanced microstructural characterization was performed on LPBFed 316 L sample along with after tests understand underlying mechanisms. results that an inhomogeneous/discontinuous inner oxide layer formed L, contrast continuous specimen. This...
The oxide films formed on AISI 316L(NG) in the temperature range have been characterized by impedance spectroscopy and ex situ analysis using Auger electron spectroscopy. Relatively thick containing a high concentration of mobile defects form stainless steel high-temperature borate electrolyte, but their response is most probably controlled properties thin barrier sublayer. ability mixed conduction model for passive to reproduce experimental data both alloy/oxide/electrolyte...
Corrosion mechanism of 316 L stainless steel produced by laser powder bed fusion-hot isostatic pressing (LPBF-HIP) and metallurgy-hot (PM-HIP) is studied with in-situ electrochemical impedance measurements coupled to detailed oxide film characterization. Quantitative analysis spectra using the Mixed-Conduction Model estimation local kinetic transport parameters interpretation in-depth elemental composition profiles indicated lower corrosion oxidation rates LPBF-HIP PM-HIP materials in...
