Title : Anti-wear properties of ZnO and Si C nanoparticles with 1-octyl-3-methylimidazolium 3-phenyl- dodecyl benzene sulphonate as smart complex additive
Abstract:
Silicon carbide is recognized as a potential, environmentally friendly SiC with ZnO for lubricant additives. A tribomete is used to test the anti-corrosion and anti-wear properties of a dispersed nanocomposite of SiC and produced ZnO nanoparticles in an ionic liquid (1-octyl-3-methylimidazolium 3-phenyl-dodecylbenzene sulphonate ,ASD). With the use of 1H-NMR, FT-IR, and mass spectrometry (MS), the great purity of these ionic liquids was confirmed. The effects of modified ZnO and SiC morphology and concentration on tribological behaviors and worn-out appearance are investigated. The compositional variance of wear resistance is explored in order to look at prospective anti-wear techniques. According to research, ZnO complex with Sic is the most suitable morphology. The synergistic effect exhibits exceptional tribological qualities and can successfully sustain the load capacity and stability of the lubricating film.
ASD is used to create complexes with ZnO and SiC in base oils. ASD had increased wear resistance up to 1000 ppm. As a result, ASD reacts with ZnO, and SiC works to produce a stable layer, increasing the lubricating oil's resistance to wear and corrosion on the contacting surface. ZnO is more effective in preventing wear because it reacts easily with ASD. Additionally, it has been concluded that ASD adsorbed on steel surfaces effectively prevents metal surfaces from coming into touch with one another.
Audience Takeaway Notes:
- Authors have been successfully synthesized new compound of 1-octyl-3-methylimidazolium 3-phenyl-dodecylbenzene sulphonate (ASD). The phenyl group attached with carbon number 3 in hydrocarbon chain C12 and carefully characterized with 1 H-NMR, FT-IR and MS analysis. The results indicated that the synthetic procedure yields highly pure products and its chemical structure effect of degree complex adsorption. As the results ASD enhance degree of anti-wear efficiency.
- It is clear that anti-wear efficiency increases by around 90% when the ratio of ZnO/SiC is 0.5 weight percent and there are 1000 ppm of ASD. The authors suggest that additive molecule ASD disperse ZnO/SiC particles in oil phase and form complex attach to contact metal surface, as results wear and corrosion decrease.
- ZnO was prepared in our laboratory, The resultant powder was calcined at 500°C for two hours and confirmed by TEM and X-ray diffraction.
