In this direction, an effort has been made to improve the poorer corrosion resistance performance of conventional monolayer nickel–titanium (NiTi) alloy coatings (due to inherent induced type of codeposition), their multilayer alloy coatings have been developed. CMM (NiTi) alloy coatings have been fabricated electrolytically on mild steel (MS) from a citrate bath, using the glycerol as additive. Multilayer alloy coatings of varying matrices have been developed by periodic modulation of direct current (DC), in terms of pulse height and pulse duration. Coating configurations in both composition and thickness of alternate layers were optimized for best performance of the alloy coatings against corrosion. Corrosion behaviours were evaluated by electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization methods. Experimental study revealed that the corrosion rate (CR) of CMM coatings decreased successively with increase in number of layers up to certain limit, and then started increased. Experimental findings demonstrated that CMM (NiTi) alloy coating having optimal configuration, represented as (NiTi)2.0/4.0/120 is approximately five times more corrosion resistant than its monolayer counterpart, deposited from the same bath for same duration. Development of coatings in layered pattern was confirmed by scanning electron microscopy (SEM) analyses. EDX and XRD techniques confirms the composition and phase structure of alloy coatings.

The direct evidence that barium cations remain inert towards the NICr monolayer while analyte cations localize in the monolayer in close proximity to the sulfur atoms of the ionophore groups was provided by XSW method. The effect of such preorganization on the efficiency of silver-ion binding by NICr monolayers at interfaces was studied. Fluorescence spectra of monolayers and Langmuir–Blodgett films obtained from them were used as a response signal to the sensor-analyte interaction. It is important to note that in the presence of Ag+ the fluorescence intensity of the studied planar systems increases, which is most convenient for registration (“switch-on” sensors). It was demonstrated that monolayer preorganization leads to an increase in the response signal to silver ion binding by 2–2.5 times.

AA7075-T6 (aluminum–zinc) has the best mechanical properties of all aluminum alloys. However, its corrosion resistance is low. In this work, ocimum basilicum seeds (OBS) have been evaluated as a corrosion inhibitor for the AA7075-T6 in 3.5% NaCl solution, using electrochemical methods, surface analysis, and theoretical investigation. The obtained results show that OBS significantly decreases the reactivity of the alloy, and thus provides more effective corrosion protection. The inhibition efficiency increases as the inhibitor concentration increases, reaching a maximum of 93% for 0.50 g/L. Furthermore, the IE measurement shows that OBS behaved as a mixed-type inhibitor. Electrochemical impedance spectroscopy (EIS) measurements corroborate these results and show that OBS increases the corrosion resistance of the aluminum alloy 7075 T-6 in 3.5% NaCl solution. SEM-EDAX and AFM images showed the presence of OBS on the surface of aluminum due to its adsorption. To further investigate the reactivity of the level 6-31G (d, p) was examined using DFT (B3LYP) approach. The molecular dynamics simulations have shown that the OBS is adsorbed in parallel mode on the surface of aluminum. In addition, the adsorption energy (Eads) shows the stability of the adsorptive system and confirms the reliability of our experimental results.","PeriodicalId":745,"journal":{"name":"Protection of Metals and Physical Chemistry of Surfaces","volume":"60 2","pages":"304 - 319"},"PeriodicalIF":1.1,"publicationDate":"2024-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142518812","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}
