Ti-6Ta exhibits superior corrosion resistance and repassivation ability in the liquid phase compared to the vapor phase, whereas pure titanium shows enhanced performance in the vapor phase compared to the liquid phase. This reversal behavior can be attributed to the phase-dependent composition of the passive films. X-ray photoelectron spectroscopy analysis reveals that the liquid-phase passive film on Ti-6Ta has a significantly higher content of protective oxides (12 % Ta₂O₅, 37.3 % TiO₂) compared to the vapor-phase film (10.9 % Ta₂O₅, 29.7 % TiO₂). In contrast, the liquid-phase film on pure titanium retains a lower protective TiO₂ content (46.4 %) than that in its vapor-phase film (54.9 %). First-principles calculations indicate that tantalum enhances corrosion resistance by elevating surface work function, increasing oxygen vacancy formation energy, and promoting dense Ta₂O₅-TiO₂ composite passive films with phase-dependent composition.

This work investigates the corrosion response of LPBF-processed AlSi9Cu3 alloy under different heat treatments, focusing on the correlation between melt pool features, microstructure, and corrosion mechanisms. In the as-built condition, the alloy exhibited a well-defined melt pool structure with Si- and Cu-rich precipitates concentrated along the melt pool boundaries. These precipitates acted as efficient cathodic sites, driving micro-galvanic interactions and leading to an inter-melt pool corrosion morphology. Low-temperature heat treatments preserved the melt pool structure while promoting the precipitation of additional Cu- and Si-rich phases. This increased the galvanic interactions and exacerbated selective corrosion, producing a more severe inter-melt pool attack. Solution treatments dissolved and redistributed the precipitates, producing a more homogeneous microstructure. The resulting reduction of galvanic coupling significantly improved corrosion resistance and promoted a more uniform corrosion morphology. Conversely, artificial aging promoted the precipitation and coarsening of Cu-rich phases, which increased intergranular corrosion susceptibility.
