“…The bands at 1578 and 1454 cm -1 in both ionic liquids correspond to C=C and C=N stretching vibrations of the imidazole ring, respectively. The bands at 1222 and 1023 cm -1 are assigned to the S-O and S-OH stretching vibrations of HSO 4 [40].…”

“…Hence, the stretching frequency at 1000 cm À1 is related to the vibrations of C-O bond on the mild steel surface. [49][50][51] The spectroscopy studies conrmed the chemisorbed phytochemicals on the mild surface. As shown in XRD of Fig.…”
“…[29] The corrosion products are containing mainly metal fluorine and metal oxide on the surface which are experimentally verified. [30] After detailed investigation, halogenated ILs have hazardous and toxic effects to the environment and corrosive nature towards the engineering surfaces. The halogenated ILs can produce toxic and corrosive products after decomposition under different tribo-chemical reaction conditions for environment and the surface-engineering.…”
Section: Tribological Performance Of Halogenated Ionic Liquidsmentioning
Our main focus is to report the tribological properties of ionic liquids (ILs). Mainly, lubricating of ILs has been reported to understand the applicability of ionic liquids (ILs) in petroleum-based lubricant industry and energy conversion process as oil additive. The influence of counter parts of ILs on tribological property has been reported for designing efficient lubricating and oil-additive property of ILs. The effect of halogenated and nonhalogenated ILs on corrosion is also reported during tribological studies at different metal surface. Further, role of ILs as oil-additive has been discussed in terms of better tribological performance. Structure modification and role of anion on better performance of tribological property have been mentioned for enhancing effectiveness of lubricant and oil-additive properties. Origin of corrosion and thin film formation on metal surface are also discussed in detailed using different types of ILs and metal surfaces.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
