The corrosion behavior of Inconel 625 and the nitrogen-containing nickel-based cladding layer in a mixture of 75% Na₂SO₄ + 25% NaCl at 700°C was studied, and its mechanism was analyzed. The results of corrosion weight loss show that the corrosion weight loss per unit area of Inconel 625 is 2.95 times that of the nitrogen-containing nickel-based alloy. The results of XRD, SEM of surface corrosion and elemental distribution indicate that the phase compositions of Inconel 625 and the nitrogen-containing nickel-based alloy after corrosion are basically the same, all containing Cr₂O₃, NiO, Fe₂O₃, NiCr₂O₄, and Ni₃S₂. NiFe₂O₄ was also detected in the nitrogen-containing nickel-based cladding layer. Through the cross-sectional morphology and elemental distribution after the corrosion of the cladding layer, it can be seen that a chromium-depleted layer appears in Inconel 625 after corrosion, while it was not observed in the nitrogen-containing nickel-based cladding layer. In summary, the corrosion resistance of the nitrogen-containing nickel-based cladding layer to the Na₂SO₄ + NaCl molten salt is better than that of Inconel 625. It can be proved through the corrosion mechanism and XPS that Cr₂O₃ plays a crucial role in it.</p></div>","PeriodicalId":18225,"journal":{"name":"Materials and Corrosion-werkstoffe Und Korrosion","volume":"76 4","pages":"581-590"},"PeriodicalIF":1.6,"publicationDate":"2025-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143809496","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}

Characterization results indicate that the dense native oxide layer naturally present in Ti may contain more defects in the implanted materials due to the implantation process, especially when Ag is implanted. The material co-implanted with Ag and Cu presents an outer oxide layer with Ag and Cu nanoparticles which are the source of ions that can act as bactericidal agents.

The aim of the work was to determine the effect of frequency and amplitude of the pulsed bias voltage (U<sub>B</sub>) on the elemental and phase composition, mechanical, and corrosion properties of Cr−O−N coatings. They have an amorphous structure with embedded nanosized solid solution crystallites based on CrN with a cubic structure and Cr<sub>2</sub>O<sub>3</sub> with a rhombohedral structure. The increase in the bias voltage results in a reduction in the grain size of the Cr<sub>2</sub>O<sub>3</sub> and CrN phases by about four times to about 5 nm, as well as a change in the CrN phase content in the coating. The lattice parameter increases slightly for the Cr<sub>2</sub>O<sub>3</sub> phase but decreases for the CrN phase. The increase in the pulse frequency results in an increase in the CrN phase content in the coating and the lattice constant of both phases and a slight decrease in the crystallite size. The hardness of Cr−O−N coatings slightly increased with the U<sub>B</sub> from 26 ± 1 GPa (DC) to 28 ± 1 GPa (−300 V, pulsed), and the elastic modulus ranges from 290 to 310 GPa. The greatest changes were observed in corrosion resistance. With an increase in the bias voltage and pulse frequency, the corrosion current of Cr−O−N coatings on steel in 3% NaCl solution decreased by three orders of magnitude compared to coatings deposited at DC voltage and by five orders of magnitude compared to the base steel. Therefore, the use of a pulsed bias voltage with a frequency of at least 10 kHz and an amplitude of 700 V can significantly increase the corrosion resistance of Cr−O−N coatings on steel substrates.</p></div>","PeriodicalId":18225,"journal":{"name":"Materials and Corrosion-werkstoffe Und Korrosion","volume":"76 4","pages":"542-556"},"PeriodicalIF":1.6,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143809926","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}
