Precious metals exhibit the best corrosion resistance, but it is impossible to directly used due to extremely high cost for conventional bulk or plate structure. Herein, a novel coated RuO<sub>2</sub>-IrO<sub>2</sub> inert anode with double-layer structure was proposed in chloride molten salt. IrO<sub>2</sub> as intermediate layer and RuO<sub>2</sub> as top layer are step by step coated on a titanium current collector. Dense RuO<sub>2</sub>-IrO<sub>2</sub> coating with good adhesion with titanium substrate is formed via thermal treatment. RuO<sub>2</sub>-IrO<sub>2</sub> coating is chemically and electrochemically stable in typical CaCl<sub>2</sub>-NaCl molten salt. Coated RuO<sub>2</sub>-IrO<sub>2</sub> inert anode can achieve long-term and stable electrolysis for 100 h in chloride molten salt under harsh and fluctuating conditions. It is confirmed that excellent stability is ascribed to in-situ formation of complex perovskite oxide with high-valence Ir(VI) and Ru(VI). For CO<sub>2</sub> electrolysis as a representative case, coated RuO<sub>2</sub>-IrO<sub>2</sub> inert anode exhibits good stability and deliver a high current efficiency of 89.8 %. High-purity carbon is easily obtained. This study highlights a surface-engineered strategy to design robust and cost-effective inert anodes for molten salt electrochemical metallurgy and related high-temperature electrochemical processes in harsh chloride molten salt.</div></div>","PeriodicalId":290,"journal":{"name":"Corrosion Science","volume":"262 ","pages":"Article 113650"},"PeriodicalIF":7.4,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146036904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The weight-loss tests, electrochemical tests, and analyses of biogenic H₂S and H₂ gases, as well as SCC crack morphology, were used to investigate the MISCC behavior of different biofilm distributions. The results show that a smaller biofilm distribution causes more severe microbiologically induced corrosion (MIC) because of a higher SRB cell count, following the extracellular electron transfer MIC (EET-MIC) mechanism, which leads to increased weight loss and blunter SCC cracks. Conversely, a larger biofilm distribution results in less weight loss and sharper SCC cracks over the 14 days. Higher levels of biogenic H₂S and H₂ were associated with more active microbiologically induced stress corrosion cracking (MISCC), resulting in deeper, more pronounced cracks in environments with more extensive biofilm distribution.

Applications of LPBF IN718 with high strength in hydrogen-rich environments are limited by their low hydrogen embrittlement (HE) resistance. Keeping this in view, we examine the role of solutionizing temperature on the strength and HE resistance of solutionized and double aged (SA) LPBF IN718 with the aid of slow strain rate tensile (SSRT) tests that are conducted in air as well as in situ hydrogen charging conditions. Results reveal that solutionizing at a relatively low-temperature of 980 °C (LSA) enhances strength while maintaining HE resistance comparable to the as-built alloy, owing to retained dislocation cellular networks decorated with the Laves phases and nanoscale γ'/γ'' precipitates that promote uniform hydrogen distribution and suppress strain localization. In contrast, high-temperature solutionizing at 1150 °C (HSA) results in the dissolution of cellular structures and recrystallization and grain growth that leads to a microstructure with coarse equiaxed grains. The latter facilitate rapid hydrogen diffusion along their boundaries, which results in severe intergranular cracking. These findings demonstrated that controlled, lower-temperature solutionizing enables a balanced optimization of strength and HE resistance in LPBF-produced precipitation-strengthened superalloys, providing valuable guidance for the post-processing design of materials intended for applications in hydrogen-rich environments.</div></div>","PeriodicalId":290,"journal":{"name":"Corrosion Science","volume":"262 ","pages":"Article 113642"},"PeriodicalIF":7.4,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146036902","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
