Abstract |

内容記述 |
The impact of femtosecond laser texturing (FLT) on the corrosion and stress corrosion cracking (SCC) behavior of binder jet printed (BJP) 316L stainless steel, both in its as-printed form and after hot isostatic pressing (HIP), is investigated. Hierarchical micro- and nano-surface architectures were produced using FLT through 200, 400, and 800 laser passes, corresponding to low-, medium-, and high-depth textures, respectively. The latter two resulted in superhydrophobic surfaces, while the low-depth texture imparted superhydrophobicity to BJP 316L but only hydrophobicity to BJP+HIP 316L. Compared to the low-depth textures, the medium- and high-depth textures significantly reduced the adhesion of corrosive media. Cyclic potentiodynamic polarization tests showed that FLT enhanced localized corrosion resistance in BJP 316L but diminished it in BJP+HIP 316L. Corrosion rates correlated directly with increasing surface roughness, following the order 200 < 400 < 800 passes. Crucially, medium-depth FLT markedly improved SCC resistance in BJP 316L. Post-FLT, the SCC performance of BJP 316L matched that of their HIP-treated counterparts. These findings demonstrate that FLT is a promising post-processing strategy to bolster both localized corrosion and SCC resistance in additively manufactured 316L stainless steel. |
