Through meticulous experimentation and analysis, several key findings were uncovered: Heat treatment enhances the volume fraction of the B19' martensite phase and refines the distribution morphology of Ti-C carbides. Such microstructural alterations yield a moderate enhancement in alloy strength, though there is a slight decline in superelasticity performance. Heat treatment profoundly elevates the corrosion resistance of NiTi shape memory alloys in dilute sulfuric acid solutions. This is evidenced by a notable rise in corrosion potential, a marked reduction in corrosion current density, an increase in charge transfer resistance, and an elevation in the flat band potential of the passivation film on the alloy surface, accompanied by a decrease in carrier concentration. These improvements in corrosion resistance largely stem from the fact that heat treatment markedly optimizes the alloy's microstructure and compositional uniformity. Consequently, this enhances the consistency and stability of the passivation film on the alloy's surface, ensuring more reliable performance of NiTi shape memory alloys in acidic conditions.</div></div>","PeriodicalId":13872,"journal":{"name":"International Journal of Electrochemical Science","volume":"20 5","pages":"Article 100976"},"PeriodicalIF":1.3,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143529676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, although much work is related to the microstructures and mechanical properties of Ti-B12 alloys, their corrosion behavior, especially in the solution containing lactic acid, is still unclear. This work investigated the microstructures and electrochemical corrosion behavior of Ti-B12 alloys in Hank's solution with varying lactic acid concentrations. As-cast, deformed, and annealed Ti-B12 alloys were used as the samples. The results show that lactic acid plays a detrimental role in the corrosion resistance of the alloys. When the lactic acid concentration of Hank's solution is 0.075 wt% (pH = 3), the Ti-B12 alloys exhibit the highest corrosion current densities of 0.055 μA·cm⁻², 0.078 μA·cm⁻², and 0.098 μA·cm⁻², for the annealed, as-cast and deformed samples, respectively. Correspondingly, in such a situation, the impedances of the passive films formed after open circuit potential are 1.46 MΩ·cm², 1.28 MΩ·cm^2, and 0.95 MΩ·cm², which is about two-thirds of those in the Hank's solution with pH of 7. The lactic acid dissolves the outer layer of the passive film, resulting in an increased density of oxygen vacancies. The annealed sample exhibits refined grains in the microstructure, crucial for enhancing corrosion resistance. The as-cast samples display coarser grains. The grains are broken and elongated in the rolling direction in the deformed sample, leading to inferior performance in corrosive environments. This research provides critical insights into the potential applications of Ti-B12 alloys in biomedical environments.</div></div>","PeriodicalId":13872,"journal":{"name":"International Journal of Electrochemical Science","volume":"20 4","pages":"Article 100974"},"PeriodicalIF":1.3,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143454728","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

XRD confirmed the material's crystallinity and structure, while SEM revealed quasi-spherical morphology and uniform particle distribution. FTIR identified Co–O stretching vibrations, validating the spinel framework, and XPS provided insights into cobalt oxidation states (Co²⁺/Co³⁺) and lattice oxygen. The modified electrode demonstrated superior electrochemical performance, with a 67 % increase in peak current response (from 85 μA to 142 μA) and improved electron transfer kinetics. Differential pulse voltammetry measurements under optimized conditions showed excellent analytical performance with two distinct linear ranges (0.1–10 μM and 10–100 μM). The method achieved high selectivity against common interferents at 100-fold excess concentrations, with minimal interference from caffeine and ephedrine at 10-fold excess. Analysis of ten commercial supplements showed synephrine recovery rates of 97.5–102.3 % with RSDs below 4.5 %. The method's stability was confirmed through intra-day (RSD = 2.5 %) and inter-day (RSD = 4.2 %) precision studies. This electrochemical platform aligns with current regulatory needs for accurate and reliable synephrine quantification, offering a rapid and cost-effective alternative to traditional chromatographic techniques.
