The complex interplay between such microstructural variations and porosity on the corrosion and stress corrosion cracking (SCC) properties of the 316L austenitic stainless steel produced using CM, laser powder bed fusion (LPBF), binder jet printing (BJP), and BJP+hot isostatic pressing (HIP) techniques were investigated and compared. The resistance of the steels to localized corrosion resistance has the following order: BJP < (BJP + HIP) ≈ CM < LPBF, while their SCC resistance ranked as BJP < LPBF ≈ CM < (BJP + HIP). BJP 316L’s lowest resistance is due to the combined effects of the high fractions of δ-ferrite, σ-phase and porosity present in it. The rapid solidification conditions prevalent during LPBF result in the refinement of the Mn-Si-O inclusions and complete elimination of the MnS inclusions. Both these features impart superior localized corrosion resistance to LPBF 316L. However, pit growth and crack propagation are facilitated by high residual strain within its microstructure, making its SCC resistance comparable to that of CM 316L. HIP after BJP led to a substantial reduction of δ-ferrite fraction and porosity. Both these factors significantly enhance the localized corrosion resistance and make the BJP+HIP 316L’s SCC resistance superior. The results of this work demonstrate the need for a close examination of the effect of different microstructural features and porosity induced by AM on the corrosion and SCC resistances of alloys for ensuring structural integrity of AM components in aggressive environments.</div></div>","PeriodicalId":290,"journal":{"name":"Corrosion Science","volume":"252 ","pages":"Article 112968"},"PeriodicalIF":7.4,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143882711","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}

Results unveil that the residual strain and anisotropy grains jointly deteriorate the planar SCC initiation response, while high-density low angle grain boundaries alleviate the depth attack of short-term SCC propagation. Furthermore, the cellular structure, decorated with Cr segregation and dislocation tangles, inhibits the short-term SCC propagation by enhancing the re-passivation capacity and oxide rupture resistance at the crack tip. The other concomitant factors, such as oxide precipitates and melting pools, are considered subordinate to the SCC susceptibility.

The unconventional pressure-induced supersaturation could simultaneously reduce the proportion of cathodic phases and raise the potential of the matrix. Moreover, the multiple supersaturated solutes and dense precipitates could induce a stable corrosion product layer, which serves as an effective shielding barrier to delay the corrosion process.

Nevertheless, the self-corrosion of Al anodes causes a decline in anode utilization and capacity, thereby restricting their commercial feasibility. Herein, Toona Sinensis extract (TSE) is proposed as a green electrolyte additive to reduce the self-corrosion of Al anodes in alkaline AABs. The findings indicate that the utilization of TSE offers a successful strategy for effectively suppressing the self-corrosion of Al anodes, ultimately boosting the discharge performance of AABs. Quercetin, kaempferol, nicotinic acid, phenolic acid, and α-linolenic acid were identified as the main components in TSE through a series of ex-situ/in-situ characterizations. An inhibition efficiency of 51.9 % was achieved by using an optimized electrolyte containing 0.4 g L<sup>−1</sup> TSE additive, which helped suppress the pitting corrosion of Al anodes in alkaline electrolyte. Ultimately, the AABs demonstrated a remarkable specific capacity of 2571.4 mAh g<sup>–1</sup> and anode utilization rate of 83.9 %, surpassing the initial capacity of 1278.7 mAh g<sup>–1</sup> and utilization rate of 43.2 %. Density functional theory (DFT) calculations combined with molecular dynamics (MD) simulations reveal that quercetin, kaempferol and nicotinic acid are the most active components in TSE. By forming O-Al and N-Al bonds on the Al anode surface, they can create an adsorption protective film that boosts discharge performance and corrosion inhibition effect in AABs. This work demonstrates that TSE serves as a natural electrolyte additive for AABs, providing a novel approach to improve their performance and commercial feasibility.</div></div>","PeriodicalId":290,"journal":{"name":"Corrosion Science","volume":"252 ","pages":"Article 112952"},"PeriodicalIF":7.4,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143864883","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}
