“…Its mechanism can be summarized as hydration effect [56], chemical reaction layer [57], hydrodynamic effect [58,59], double electric layer interaction which will be more important in superlubricity [60,61], and the combination of multiple effects [62]. Superlubricity lubricants have been developed from pure water [63], brine [64], acids [65] to acid-alcohol system [66,67], alcohol system [68], bioliquids [69], oil-based system [70], and surfactants [71]. The progress in 2018 is as follows:…”

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.

“…[14][15][16][17] Diamond-like carbon (DLC) coating has drawn much attention nowadays in both biomedical and engineering applications because of its low coefficient of friction, high hardness, wear resistance, chemical inertness, and good biocompatibility. [18][19][20] In the present work, DLC coating has been developed on NiÀ Ti alloy using carbon plasma immersion ion implantation method. This coating has been investigated with field emission scanning electron microscopy (FESEM), atomic force microscopy (AFM), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), electrochemical impedance spectroscopy (EIS), and potentiodynamic polarization studies in simulated body fluid (SBF).…”

Carbon plasma immersion ion implantation (PIII-C) has been performed on NiÀ Ti alloy surface using methane as a precursor gas at low temperature and it has been followed by deposition of diamond-like carbon (DLC) coating. Untreated and coated alloys are characterized with field emission scanning electron microscopy, atomic force microscopy, Raman spectroscopy, and X-ray photoelectron spectroscopy. Electrochemical impedance spectroscopy, and corrosion testing in Hanks' solution which is simulated body fluid show that corrosion resistance has been enhanced in PIII-C + DLC-coated alloy compared to untreated alloy. The in vitro studies of untreated and PIII-C + DLC-coated alloys have been evaluated using osteoblast-like cells (MG-63). Cellular behavior in terms of cell morphology along with the viability and cell spreading has been evaluated using scanning electron microscopy and in vitro cell culture assay, respectively. In comparison to Ni-Ti alloy, the coated alloy exhibits better cell viability indicating their biocompatibility.

“…Peeling, ploughing, adhesion, and other behaviors, along with the copper phase during the friction process, alleviated the rapid wear behavior of the composite materials made from the mixed powders due to friction in the water environment. [22] For the chemically etched samples, the small abrasive particles that were generated were able to fill in the gaps, thereby reducing the friction coefficient. The surface contact angle also greatly increased, which made it difficult for water molecules to penetrate into the matrix material, thereby reducing the exfoliation of graphite.…”

“…After sintering, a network structure of copper and graphite had formed, where the graphite was wrapped in the copper phase in microscopic regions, making the graphite adhesion more stable. Peeling, ploughing, adhesion, and other behaviors, along with the copper phase during the friction process, alleviated the rapid wear behavior of the composite materials made from the mixed powders due to friction in the water environment [22] . For the chemically etched samples, the small abrasive particles that were generated were able to fill in the gaps, thereby reducing the friction coefficient.…”

Copper‐graphite composites with different copper content are prepared by spark plasma sintering (SPS) at 900 °C using copper‐coated graphite powder and ordinary graphite powder as raw materials. Two groups of specimens are used for friction testing, including the original specimens and K2Cr2O7‐H2SO4‐etched specimens. The density, microstructure, Shore hardness, resistivity and friction and wear properties of the samples were investigated using the Archimedes drainage method, scanning electron microscopy, a hardness tester, a resistance tester, and a friction tester. The results showed that the relative density of the samples with different compositions reached about 90 %, and with an increase of copper content, the density and the relative density of the copper/graphite composites increased. As the copper content increased from 10 wt % to 50 wt %, the Shore hardness of the composites increased from 37 HSD to 59 HSD. Under dry‐friction conditions, with an increase of Cu wt %, the friction coefficients and wear rates of the original specimens showed a downward trend, while those of the chemically etched specimens first increased and then decreased. Under water‐friction conditions, both the original samples and chemically etched samples show very low friction coefficients, about 0.15 and 0.12, respectively, which are far lower than the friction coefficients (∼0.20) obtained under dry‐friction conditions. The wear rates of the original specimens decreased with an increase of copper content, while those of the chemically etched specimens increased first and then decrease. The electrical conductivities of the copper/graphite composites were slightly reduced by chemical etching, but the resistivity of the copper/graphite composites remained at a low level of 10−7 Ω⋅m for a copper content of 40–50 wt %.
