A novel, water-based oleic acid (OA)/2-acryloylamino-2-methyl-1-propanesulfonic acid (AMPS) copolymer was successfully synthesized as a water-based lubricant additive. The OA-AMPS copolymer was characterized by Fourier transform infrared and proton NMR spectroscopies and then used as a lubricant additive in water. The lubrication properties of water-miscible cutting fluids with the OA-AMPS copolymer additive were investigated using a four-ball friction tester. The surface of the wear scars was explored using scanning electron microscopy and X-ray photoelectron spectroscopy. The addition of the synthesized OA-AMPS copolymer improved the friction coefficient and wear scar diameter of water. The maximum nonseizure load increased from 95 to 431 N, and the anticorrosion ability on copper was categorized as 1b. Good antiwear and friction-reducing properties for water were observed and attributed to the absorption and tribochemical films composed of iron oxide and ferrous disulfide.

“…Subsequently, the negatively charged anions adsorbed on the surface because of electrostatic interaction and the cations adsorbed on the anions layer because of the interaction of anion and cation. However, the cations of [MPBIM][BMB] can also be directly adsorbed on the surface of steel ball owing to the strong polarity of the methoxy group, which prevent the direct adsorption of the borate anions (Han et al , 2017; Yang et al , 2011; Jin et al , 2016; Ning et al , 2015). Compared with [MPBIM][BMB], the higher kinematic viscosity of [OBIM][BMB] helps to form a thicker oil film on the steel surface and then effectively decrease the chance of direct contact between the two friction pairs (William et al , 2014).…”

Purpose The purpose of this paper is to investigate the tribological properties, antiwear mechanism and anticorrosion properties of two novel halogen-free borate ionic liquids (ILs) in 500 N base oil. Design/methodology/approach Different qualities of borate ILs were added to 500 N, and their tribological properties were tested on a four-ball machine. The tribological properties of the additives were evaluated by measuring the wear scar diameter (WSD) and average coefficient of friction. The antiwear and antifriction mechanism of ILs was analyzed by energy dispersive spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS). Findings The corrosion degrees of the two borate ILs 1-butyl-3-octyl-imidazole bis(mandelato)-borate ([OBIM][BMB]) and 1-butyl-3-(3-methoxypropyl)-imidazole bis(mandelato)-borate ([MPBIM][BMB]) are 1b and 1a, respectively, suggesting that they both possess significant corrosion resistance and can effectively protect the steel surface. When the concentration of [OBIM][BMB] and [MPBIM][BMB] is 2.5 Wt.%, the friction coefficient of 500 N is reduced by 37.3% and 26.2%, respectively. According to the analysis of the thermo gravimetric analyzer curves, [OBIM][BMB] and [MPBIM][BMB] decomposed at 369.7°C and 374.3°C, respectively, indicate that two additives both can be applied in higher temperature condition. The results of XPS and scanning electron microscope (SEM) reveal that [OBIM][BMB] and [MPBIM][BMB] both can react with the steel surface, thereby forming chemical films composed of iron oxide, B2O3 and organic N-containing compounds. Originality/value Two new environmentally friendly borate ILs were synthesized and their tribological properties in 500 N base oil were investigated for the first time.

“…In Quinoline is an N-containing heterocyclic compound. Several studies have reported that N-containing heterocyclic compounds possess excellent anti-wear properties, and the unbound pair of electrons of the N atom may form a coordinated film with the metal surface (Singh et al,1990;Ning et al, 2016;Xiong et al, 2016). For a proper study of the tribological performance, regular platelet morphology of ZrPOF-Q1 was obtained through a slightly modified version of the method described by Liu et al (2009).…”

Purpose The purpose of this paper is to study the tribological properties of (C9H8N)4(H2O)4[Zr8P12O40(OH)8F8] (designated as ZrPOF-Q1) used as an additive in lithium grease. Design/methodology/approach The tribological properties of ZrPOF-Q1 as an additive in the lithium grease were evaluated with a four-ball tester. To understand the lubrication mechanism, post-test characterization of the contact tracks was performed via three-dimensional (3D) optical profiler, scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS). Findings The results reveal that ZrPOF-Q1 exhibits good performance in anti-wear, friction-reducing and load-carrying capacity. The action mechanism is estimated through analysis of the worn surface with SEM, EDS and 3D. The results indicate that ZrPOF-Q1 can adhere on the substrate, protecting the rubbed surfaces from a direct contact, even under high load for a long-time test. ZrPOF-Q1 can adhere on the substrate, protecting the rubbed surfaces from a direct contact, even under high load for a long-time test. Originality/value This work illustrates that ZrPOF-Q1 as an additive can improve lubricating performance. These tribological properties make ZrPOF-Q1 a promising candidate for lubricant additive.
