This study investigates the corrosion resistance and stability of a series of Ti substrates implanted with Ag and Cu ions, as well as a combination of both. 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. Finally, the study shows that the implantation of Ag and/or Cu ions does not lead to a deterioration of the corrosion resistance of Ti under simulated physiological conditions.</p></div>","PeriodicalId":18225,"journal":{"name":"Materials and Corrosion-werkstoffe Und Korrosion","volume":"76 4","pages":"591-603"},"PeriodicalIF":1.6,"publicationDate":"2024-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143809922","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}

WC increases the hardness of the LPBF MMCs. WC offers W and C to the matrix during laser scanning, with C diffusing to the matrix to form austenite and Cr-rich carbides. The austenite content increases with higher tempering temperatures by up to 22% after heat treatment at 400°C. However, more numbers and large size Cr-rich carbides are formed after being tempered at 600°C. Austenite increases pitting corrosion resistance by a higher critical pitting potential and lower pit growth kinetics. Wear resistance is linearly related to the hardness value, with smaller grain and more austenite improving ductility without sacrificing tensile strength.

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}

The phase composition of the formed scale was determined by X-ray diffraction. Laboratory-induced hydrogen atmosphere was adopted through cathodic charging.

Understanding the intricate relationship among the contributing factors such as flow dynamics, environmental factors, and corrosion reactions is essential for developing effective prediction and mitigation strategies. This review discusses the recent advancements in the numerical modeling of FAC using computational fluid dynamics (CFD). The numerical models presented show abilities to predict FAC profiles across multiple power plant components, and a review was conducted on the evaluation of these predictions with experimental measurements. Notably, increased turbulence in the flow significantly contributed to prediction errors, emphasizing the need for advanced turbulence models in numerical simulations of FAC. Addressing these challenges is crucial for maintaining sustainable infrastructure and reducing industrial risks through enhanced predictive maintenance strategies.</p></div>","PeriodicalId":18225,"journal":{"name":"Materials and Corrosion-werkstoffe Und Korrosion","volume":"76 3","pages":"368-385"},"PeriodicalIF":1.6,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143555202","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}
