The result shows that as the aging temperature increased from 480°C to 620°C, the material strength gradually decreases, and the HE resistance first increases and then decreases. Among them, the material aged at 580°C exhibits the lowest HE susceptibility (about 9.96 %). The fracture morphology changes from a cleavage fracture to an intergranular fracture and then to a quasi-cleavage fracture. This is mainly related to the microstructure transformation of the Cu-rich precipitates. The diffuse Cu precipitated at 480°C strongly pins the dislocations, thereby triggering cleavage fracture based on the hydrogen-enhanced decohesion mechanism (HEDE) model. When the precipitated phase transforms into BCC-Cu (520°C), local deformation at the grain boundaries causes intergranular cracking based on the HEDE model and hydrogen-enhanced decohesion mechanism (HELP) model. Moreover, when the aging temperature increases to 580°C, 9R-Cu with a lower distribution density forms. It can generate a large number of dislocation clusters through the Orowan mechanism, thereby inhibiting the segregation of dislocations and hydrogen, and delaying cracking. however, the FCC-Cu formed at 620°C cannot effectively hinder the movement of dislocations, resulting in dislocation segregation caused by the effect of hydrogen, which leads to premature fracture at a relatively low strength. This study suggests that appropriate precipitate phase structure and distribution can enhance the material's resistance to HE by reducing dislocation aggregation and weakening interfacial stress.</div></div>","PeriodicalId":290,"journal":{"name":"Corrosion Science","volume":"256 ","pages":"Article 113160"},"PeriodicalIF":7.4,"publicationDate":"2025-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144588916","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}

Copper corrosion in the alkaline CMP slurry, particularly in the presence of hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>), poses a significant challenge. The use of corrosion inhibitors, such as 1,2,4-triazole (TAZ) and its derivatives, is essential to improve the performance of copper interconnects. This study investigates the corrosion inhibition of three triazole derivatives, 3-amino-1,2,4-triazole (ATA), 3-mercapto-1,2,4-triazole (MT) and 3-amino-5-mercapto-1,2,4-triazole (AMTA), for copper in alkaline CMP slurry. Electrochemical measurements reveal that ATA exhibited the highest inhibition efficiency of 92.7 % at 10 mM, followed by MT (89.9 % at 20 mM) and AMTA (83.7 % at 20 mM). All three derivatives are mixed-type inhibitors, predominantly exhibiting anodic inhibition characteristics. An antagonistic effect occurs when the mercapto group (-SH) and amino group (-NH<sub>2</sub>) are present within the triazole ring. Surface characterization using atomic force microscopy (AFM) and scanning electron microscopy (SEM) confirms that ATA significantly improves the surface quality of copper. X-ray photoelectron spectroscopy (XPS) analysis shows that the presence of H<sub>2</sub>O<sub>2</sub> oxidizes the -SH into disulfide bonds (S-S), thereby reducing the corrosion inhibition performance of MT and AMTA. Theoretical calculations further show that ATA adsorbs parallel to the copper surface, while MT and AMTA adsorb in an inclined mode. These findings provide guidance for the design and development of new organic azole inhibitors for copper CMP processes.</div></div>","PeriodicalId":290,"journal":{"name":"Corrosion Science","volume":"255 ","pages":"Article 113164"},"PeriodicalIF":7.4,"publicationDate":"2025-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144571810","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}

Laser treatment creates a smooth and dense YbMS-rich layer at surface of the YbDS coating. Short-term corrosion results demonstrate that molten CMAS infiltrates to a depth of ∼23 µm in the untreated YbDS coating, but is blocked at the surface of the laser-treated sample. After long-term corrosion, the untreated YbDS coating is almost fully permeated, whereas nearly one-third of the laser-treated coating remains intact. Further investigation demonstrates that, apart from the reduced roughness and denser surface caused by laser remelting, the YbMS-rich layer also contributes to the improved CMAS resistance.

Novel insights show that the dislocation cells, characteristic for the SR L-PBF microstructure, form a beneficial hydrogen trap and establish an effective barrier against hydrogen-induced crack propagation and hydrogen embrittlement. Furthermore, the chemical heterogeneity in the dislocation cells contributes to crack arrest. In contrast, the mobile dislocations in HIP L-PBF 316L make this homogeneous microstructure significantly more prone to hydrogen embrittlement due to the promoted hydrogen-induced martensite formation, driving brittle crack propagation. Therefore, a dual HEDE-HELP synergetic mechanism is proposed for the hydrogen-induced embrittlement of SR L-PBF 316L, whereas HIP L-PBF 316L is dominated by the HEDE embrittlement mechanism.
