The benefits of this approach over arc welding include a smaller heat-affected zone, residual stress reduction, and material savings. In particular, wire-directed energy deposition (DED) is a suitable technique because of its low material cost and high rate of production compared to other additive manufacturing methods. However, metallurgical variations in composition, phase fraction, and microsegregation can potentially influence the corrosion behavior of such claddings. In this work, 309L SS is clad on carbon steel substrates and electrochemical methods are used to measure their general and pitting corrosion resistance in simulated marine environments (3.5 wt.% NaCl solutions). Two-layer claddings are fabricated with four laser powers to understand the effects of bulk chemical composition, austenite / δ-ferrite phase fractions, and individual phase compositions on corrosion behavior. The two-layer claddings are compared to a single layer cladding, wrought 304 SS, and the carbon steel substrate for a comprehensive assessment of corrosion performance. The two-layer claddings are remarkably resistant to general corrosion in the 3.5 wt.% NaCl environment because of their high Cr content (21.6 – 23.3 wt.% Cr). The single layer cladding exhibits localized corrosion at unmixed Fe-rich peninsulas that originate at the dissimilar metal boundary and protrude into the first cladding layer. All two-layer claddings possess higher pitting corrosion resistance than wrought 304 SS, demonstrating their effectiveness as a corrosion-resistant barrier. The pitting corrosion resistance is superior for claddings made with lower laser powers, due to low dilution and greater δ-ferrite contents.","PeriodicalId":10717,"journal":{"name":"Corrosion","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2023-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45590289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to overcome this problem, an environment-friendly physical anticorrosion scheme based on magnetic field (B) has been proposed. In this context, we investigate the effect of Lorentz force and gradient force of magnetic field on the corrosion behavior of carbon steel in seawater. The experimental results show that the gradient force of magnetic field inhibits corrosion while the Lorentz force promotes corrosion. Especially in B⊥E (corrosion electrical field) case, the Lorentz force influence on the corrosion behavior is greater than the gradient force, while in B//E case gradient force dominates. In addition, the effect mechanism of magnetic field on the corrosion behavior of carbon steel in seawater was revealed by comparison of corrosion product composition in different reaction regions and electrochemical impedance spectrum analysis, which will provide experimental basis for the application of environment-friendly Marine anticorrosion technology based on magnetic field.","PeriodicalId":10717,"journal":{"name":"Corrosion","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43063581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have previously reported that hydrogen embrittlement in 7xxx alloys originates from trapped hydrogen at the MgZn2 precipitate interface, providing high hydrogen trapping energy. We propose the dispersion of Mn-based second-phase particles as a novel technique for preventing 7xxx aluminum alloy hydrogen embrittlement. In this study, the deformation and fracture behaviors of high hydrogen 7xxx alloys containing 0.0% Mn and 0.6% Mn are observed in situ using synchrotron radiation X-ray tomography. Although no significant differences appear between the two alloys regarding the initiation of quasicleavage cracks, the area fractions of final quasicleavage fractures are 16.5% and 1.0% for 0.0%Mn and 0.6%Mn alloys, respectively; this finding indicates that the Mn addition reduces hydrogen-induced fractures. The obtained macroscopic hydrogen embrittlement is quantitatively analyzed based on hydrogen partitioning in alloys. Adding 0.6% Mn, generating second-phase particles with high hydrogen trapping abilities, significantly suppresses hydrogen-induced quasicleavage fracture. The results of an original hydrogen partitioning analysis show that the dispersion of Mn-based particles (Al12Mn3Si) with high hydrogen trapping abilities reduces the hydrogen concentration at the semicoherent MgZn2 interface and suppresses hydrogen embrittlement.","PeriodicalId":10717,"journal":{"name":"Corrosion","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2023-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49280995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The absence of a liquid electrolyte allows direct recording of the electrolyte-unaltered coating response to environmental stressors. Exposures included humidity between 23 and 95%, temperatures between 10 and 50°C, 720 hours of ISO 9227 neutral salt spray, 1 year in mild continental urban climate, and for comparison, 3 years of ISO 16773 3.5% NaCl immersion. The coatings showed significantly different temperature susceptibility of impedance revealing two temperature ranges with activation energies corresponding to ionic conductivity below 20°C and conductivity influenced by polymer chain movements above 30°C. Impedances measured for intact coatings or impedances calculated from the assumed range of dielectric constant and coating thicknesses can be used as references. The EIS outcome of the laboratory tests and the time- and temperature-resolved EIS responses under atmospheric exposure were compared with the reference impedances of the coatings. Mild continental climate exposure at temperatures < 35°C and immersion at 23±2°C yielded better barrier performance for the two solvent based coating systems compared to the two waterborne systems of comparable thickness and number of layers. The NSS test that proceeds at 35°C yielded better performance of the both solvent based coatings over the waterborne coatings, regardless of the thickness. EIS quantification of barrier performance, which excludes the influence of the liquid electrolyte, has provided insight into the temperature effect on barrier behavior of the coatings under non-accelerated and accelerated exposures and the final coating rating.","PeriodicalId":10717,"journal":{"name":"Corrosion","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2023-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43304435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The fluoride-induced corrosion performance of HESPed GTD-111 and its solution-annealed counterpart is comparatively studied using immersion tests, grazing-incidence X-ray diffraction (GI-XRD) analysis, electrochemical techniques and glow discharge optical emission spectroscopy (GDOES). As supported by the immersion tests and electrochemical measurements, HESPed GTD-111 exhibits corrosion film with higher resistance and lower passivity current density at the expense of a higher initial corrosion rate. Both samples suffer pitting corrosion; however, the solution-annealed one shows deeper and larger pits. The dense distribution of crystallographic defects on the surface of HESPed sample significantly increases the diffusion of alloying elements to the corrosion front. The GDOES depth profiles reveal that (i) a thicker corrosion film with a higher contribution of alloying elements (namely, Cr, Ti, Co, and Al) is developed on the HESPed sample, and (ii) the corrosion films formed on the solution-annealed and HESPed samples consist of an outer F-rich part and an inner O-rich region.

The results have revealed that the (111) plane exhibits a higher corrosion rate compared with (001) and (101) planes. The increased temperature promotes the anodic dissolution of the substrate, accelerating the formation of corrosion products and the transformation of β/γ-FeOOH to α-FeOOH/Fe3O4. In the immersion environment, the corrosion mechanism is a typical oxygen-absorbing corrosion mechanism. During the electrochemical reaction phase, the corrosion rate shows a trend of first increasing and then decreasing with the increase of Cl− concentration, which can be explained by the catalytic dissolution effect and the protective effect of adsorbed Cl− on the surface. Meanwhile, with the injection of Cl−, the content of dissolved oxygen in the solution decreases and the adsorption competition between Cl− and oxygen increases, leading to the reduction of corrosion rate and inhibiting the formation of oxide film. The two stages of corrosion in an immersion environment are described, and the corrosion mechanism is elucidated.","PeriodicalId":10717,"journal":{"name":"Corrosion","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2023-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45228179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
