“…Some of the coatings associated with superlubricity have been introduced in the superlubricity section and are not covered in detail again. Here, several new advances in tribological-related coating technology are briefly introduced, such as oxide coating [183][184][185][186], metal coating [187,188], composite coating [183,185,189,190], ceramic coating [191,192], and so on.…”

“…Yang et al [185] report a novel TiMoN/a-MoS x composite coatings with TiMoN solid solution grains embedded into MoS x -based amorphous matrix synthesized through magnetron co-sputtering technology, and superhardness and excellent toughness can be achieved with an ultra-low wear rate of 2×10 -11 mm 3 /(N•m) in air and a low friction coefficient of 0.1. Liu et al [186] discussed as to how to remove the oxide film from the surface of pure iron on nanoscale and found that the mechanical strength of the outer layer is much higher than that of the inner layer which is quite close to that of the pure iron substrate.…”

A review of recent advances in tribology

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.

“…Second, the Mo 3d spectra exhibit two peaks that are attributed to Mo 3d 5/2 and Mo 3d 3/2 states, respectively. Spectral deconvolution further reveals two sets of peaks, with those at 228.6 eV and 231.8 eV attributed to the Mo–S bonds, while those at 228.5 and 231.7 eV to the Mo–B bonds . Third, the S 2p spectra contain two peaks attributed to S 2p 3/2 and S 2p 1/2 states, respectively, and these peaks at the binding energies of 162.0 and 163.3 eV are assigned to the S–Mo bonds.…”

Proper lubrication is essential to the reliable and efficient operation of mechanical systems ranging from the industrial to the nanoscale. Self-lubricating materials that can self-generate and sustain concurrent ultralow friction and ultralow wear in harsh environments open up a unique realm that is unattainable by traditional external lubrication mechanisms, but developing such extraordinary materials has been a long-standing grand challenge. Here, we devise an unconventional strategy to construct a dual-phase nanocomposite (DPNC) that comprises a wear-resistant phase (TiB2) and an internal lubricant source (MoS1.7B0.3). Tribological tests demonstrate simultaneous ultralow friction coefficient (∼0.03) and ultralow wear rate (∼10–10 mm3·N–1·m–1) of the synthesized DPNC specimen in ambient environments; these superb properties remain intact after the specimen has been annealed at 400 °C in air. First-principles energetic and stress–strain calculations elucidate atomistic mechanisms underpinning DPNC TiB2/MoS1.7B0.3 as an ultimate self-lubricating material. This accomplishment solves the classic lubricity–durability tradeoff dilemma, enabling advances to meet the most challenging lubrication needs.

“…Although the average COF and wear resistance of the partially crystallized film are not the best compared with the result in open literature [69], this work concludes an effective and simple method for increasing the hardness and especially H/E, i.e., embedding the crystalline phase into its amorphous counterpart to reduce the elastic modulus by Voigt model while increase the hardness by composite effect. In addition, introducing the second phase, such as nitride phase, that has higher hardness and elastic modulus than the matrix phase can also increase the hardness and H/E [16].…”

The microstructure, mechanical and micro/nano-tribological properties of the 60NiTi film annealed at different temperature were investigated. The results reveal that annealing as-deposited 60NiTi film at 300, 375, and 600 °C for 1 h leads to structural relaxation, partial crystallization and full crystallization, respectively. Compared with the structurally relaxed structure, the partially crystallized structure exhibits increased hardness but decreased elastic modulus. This is because that the elastic modulus is reduced by Voigt model while the hardness is improved by composite effect. Due to the highest hardness and ratio of hardness to elastic modulus (H/E), the partially crystallized 60NiTi film has the lowest penetration depth and residual depth (i.e., groove depth). Besides, the results also reveal that ductile plowing is the dominant wear mechanism for all the annealed 60NiTi films. Under the condition of the ductile plowing, coefficient of friction and wear resistance are related to penetration depth and residual depth, respectively. Therefore, the partially crystallized 60NiTi film shows the best tribological performance at the micro/nano-scale. The current work not only highlights the important roles of hardness and H/E in improving the micro/nano-tribological properties but also concludes an efficient and simple method for simultaneously increasing hardness and H/E.
