Purpose – The purpose of this paper is to investigate the tribological properties of novel phosphorous-nitrogen (P-N) type additives in water. Design/methodology/approach – The tribological properties of the novel P-N additives in water are compared with a commercial lubricant additive of the P-N type using a four-ball machine. The tribological mechanism was investigated by X-ray absorption near-edge structure (XANES) spectroscopy. Findings – The experimental results indicate that the phosphoramidate derivatives possess good anti-wear and friction-reducing properties. The XANES analysis shows that the prepared compounds can form a protective film containing phosphate and/or polyphosphate that affects the tribological behavior. Originality/value – The purpose of this paper is to investigate the tribological properties of the novel P-N type additives in water.

Antimony nanoparticles, whose surfaces were modified by alkyl phenol polyoxyethylene ether (OP-10), were used as one of the types of lubricating additives in liquid paraffin (LP). The tribological properties of antimony nanoparticles as lubricating additives were evaluated and compared with those of pure LP on a four-ball test machine. The morphology and chemical composition of the worn surface were investigated and analyzed by using scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The results show that the additives can obviously improve the anti-wear and friction reducing properties of LP, which are better under high friction load. The double-layer crystal structure of antimony can be separated and glided along the cleavage plane by a friction-shear force and a normal load, respectively. The separating and gliding of antimony can form a physical adsorption film, which can separate the friction surface to avoid direct contact of the friction surface and play an important role in improving the anti-wear and friction reducing properties.

Two novel boron-nitrogen modified soybean oil additives with different length of chain structures (abbreviated as BNS1 and BNS2) were synthesized. The thermal stability of BNS1 and BNS2 was evaluated by thermo-gravimetric analysis. The effect of the as-synthesized additives on the biodegradability, anti-oxidation property, and lubricity in rapeseed oil was evaluated by respective standard method. Moreover, the morphology and tribochemical characteristics of the worn surfaces were examined by scanning electron microscope assembled with energy dispersive spectrometer. The results indicated that BNS1 and BNS2 both possess good thermal stability; BNS1 slightly impairs the biodegradability of rapeseed oil, but BNS2 facilitates the biodegradability of rapeseed oil. BNS1 and BNS2 could improve the anti-wear and friction-reducing performance of the rapeseed oil, but BNS1 exhibited better anti-wear ability as compared to that of BNS2, BNS2 exhibited better anti-wear ability in reducing friction coefficients as compared to that of BNS1. The enhanced anti-wear and friction-reducing abilities of rapeseed oil were ascribed to the formation of a composite boundary lubrication film due to the strong adsorption of BNS1 or BNS2 and rapeseed oil onto the lubricated surfaces and their tribochemical reactions with metal surfaces. BNS1 and BNS2 could both facilitate the anti-oxidation properties of the rapeseed oil.

Oil-soluble compounds containing boron as lubricating additives were restricted by the hydrolysis of borate ester. In order to overcome this problem, cerium borate nanoparticles modified with oleic acid (O-CeB) as a potential substitute for conventional lubricant additive were studied in detail. The microstructures of the prepared nanoparticles were characterized. Tribological properties of cerium borate nanoparticles used as additive in base oil were evaluated, and the worn surface of the steel ball was investigated. The results show that O-CeB possesses better anti-wear ability at relatively higher concentration; in particular, it shows better friction-reducing ability under all these studied concentrations. Under higher load, its anti-wear property and friction-reducing property are better than that of Vanlube 289 in the base oil. Based on these results of interferometric surface profilometer and X-ray photoelectron spectroscopy, it can be deduced that a continuous resistance film containing depositions and the tribochemical reaction products was formed during the sliding process.

Four ionic liquids containing dithiocarbazate were synthesized. Their antiwear and friction-reducing properties of these synthetic liquid compounds as the lubricants of a steel/steel contact were examined using an Optimol SRV oscillating friction and wear tester in ambient condition. The results indicated that the ionic liquids containing dithiocarbazate as the lubricants showed excellent friction-reducing and antiwear properties for the steel/steel pair. The introduction of the dithiocarbazate group into the molecules of the ionic liquids contributed to improve the tribological behaviour.
