“…The most popular organic additives in recent years are ionic liquids and hydrogels. Ionic liquids are commonly used as industrial lubricants or lubricant additives [89,164,165]. While hydrogels have good biocompatibility and thus they are commonly used for bio-lubrication.…”

The reach of tribology has expanded in diverse fields and tribology related research activities have seen immense growth during the last decade. This review takes stock of the recent advances in research pertaining to different aspects of tribology within the last 2 to 3 years. Different aspects of tribology that have been reviewed including lubrication, wear and surface engineering, biotribology, high temperature tribology, and computational tribology. This review attempts to highlight recent research and also presents future outlook pertaining to these aspects. It may however be noted that there are limitations of this review. One of the most important of these is that tribology being a highly multidisciplinary field, the research results are widely spread across various disciplines and there can be omissions because of this. Secondly, the topics dealt with in the field of tribology include only some of the salient topics (such as lubrication, wear, surface engineering, biotribology, high temperature tribology, and computational tribology) but there are many more aspects of tribology that have not been covered in this review. Despite these limitations it is hoped that such a review will bring the most recent salient research in focus and will be beneficial for the growing community of tribology researchers.

“…The results showed that oil‐miscible ILs offer superior anti‐wear performance especially at elevated temperature when both had comparable concentrations . The reduction of wear is as a result of the chemical reaction between IL or ZDDP and the interacting surfaces, which lead to form a tribofilm . However, the reason behind the superior anti‐wear performance of soluble IL than ZDDP at elevated temperature is still vague.…”

The reactivity of an oil‐miscible ionic liquid, phosphonium phosphate (PP), and the common anti‐wear additive zinc dialkyl dithio phosphate (ZDDP) with a solid surface at elevated temperature in the absence of any tribological motion is investigated. Understanding the thermal film build up, composition, and relative thickness will help in the understanding of lubrication mechanisms once tribological effects are introduced. Attenuated total reflection–Fourier transform infrared (ATR‐FTIR), scanning electron microscopy–energy dispersive spectroscopy (SEM‐EDS), and X‐ray photoelectron spectroscopy (XPS) are employed to characterise silicon surfaces before and after the experiments in terms of surface chemistry and surface morphology. The results show that both additives react with the silicon surface to produce thermal films. However, ZDDP forms a thicker film. PP reacts with the silicon and forms a thermal film, but the reaction rate is self‐limited such that an increase of time to 24 hours does not significantly increase the film thickness.

“…8 A remarkable reduction in friction and wear has been observed after the addition of ILs in oil-or water-based media and in grease, suggesting that ILs are promising candidate materials as neat lubricants as well as lubricant additives. 16 This study aims to synthesise benzotriazole-bearing imidazolium-based ILs, which can be used as additive to improve AW/EP, 17 antiabrasive, antioxidative, and anticorrosive properties of the lubricant. 18 The ILs were used in turbine oil formulations, and a thorough investigation has been made on the tribological properties of the lubricants ,and their performance levels are compared with turbine oils containing commercially available additive IRGALUBE 2030A.…”

Three benzotriazole‐bearing imidoazolium‐based ionic liquids (ILs) have been synthesized. The ILs were identified by 1HNMR and Fourier‐transform infrared (FTIR) techniques. The thermogravimetric analysis showed that they are highly nonvolatile and have extremely high flash points. The synthesized ILs were used in turbine oil formulation, and their lubrication properties were critically examined and compared to commercially available package additives. The tribological tests proved that the ILs act as an effective antifriction, antiwear (AW), and extreme pressure (EP) additives. Performance studies indicated that the synthesized ILs impart excellent antioxidation and corrosion protection to the lubricant with minimum acidity change. The elemental analysis proved absence of toxic and dangerous elements in the lubricant, a confirmation that the ILs are potential environmentally friendly lubricants. The results also confirmed that the synthesized ILs are ideal single‐component package additives in the lubricant industry, i.e., one molecule imparts several favorable functionalities to the lubricant..
