Abstract
The applicability of Si in low-Mo duplex stainless steel weld metals is examined in terms of corrosion resistance and impact toughness. Nano-secondary ion mass spectrometry and three-dimensional atom probe analysis indicate that Si is enriched at the outermost layer in the form of Si-oxide a few nanometer thick, leading to a significant increase in critical pitting temperature without sacrificing the impact toughness. Improved corrosion resistance suggests that the thin oxide layer possibly acts as a diffusion barrier against aggressive ionic species.
