Abstract
Whether a graphitization mechanism can control the low-friction behavior of DLC films is still controversial. In this paper, we establish the molecular dynamics model of the DLC film with graphene (DLC-GR-DLC) by LAMMPS and study the influence of the graphitization mechanism on the friction and wear behavior of the DLC film. The friction force of the DLC-GR-DLC model in the running-in stage is significantly smaller than that of the DLC film and then gradually increases to the same size as that of the DLC film. Further analysis indicates that the graphitization mechanism could indeed reduce the shear stress of the friction interface when graphene remains intact. However, the curling and breaking of the graphene structure will lead to an increase in shear force at the friction interface.

Abstract
Tribochemical wear of contact materials is an important issue in science and engineering. Understanding the mechanisms of tribochemical wear at an atomic scale is favorable to avoid device failure, improve the durability of materials, and even achieve ultra-precision manufacturing. Hence, this article reviews some of the latest developments of tribochemical wear of typical materials at micro/nano-scale that are commonly used as solid lubricants, tribo-elements, or structural materials of the micro-electromechanical devices, focusing on their universal mechanisms based on the studies from experiments and numerical simulations. Particular focus is given to the fact that the friction-induced formation of interfacial bonding plays a critical role in the wear of frictional systems at the atomic scale.

Abstract
In the present study, we obtained a-C:H films with different nanostructures by annealing from room temperature to 400 °C. The influence of the nanostructures on tribological performance in dry air and methanol environments was investigated by a reciprocating tribometer. Our results show that the tribological performance of a-C:H films follows different rules in the two environments. In dry air, tribological properties are controlled by the transfer film and mechanical properties. In methanol, friction and wear are determined by the hydrogen bonding structure, where friction coefficients relate on saturation effects of sp3-CH, and the wear properties depend on the "collapse effect" that the more the sp3-CH3 and sp3-CH2, the easier the wear out of bulk a-C:H films. Our work provides guidance for the application of a-C:H films in the methanol environment.

Abstract
Tribochemistry refers to a series of physical and chemical reactions that occur at a sliding interface under friction action, and the tribological properties of materials also change significantly. Understanding the effect of tribochemical reactions on the tribological properties of materials is important for controlling the structure and composition of materials by chemical means and promoting the engineering application of materials. This study primarily introduces the tribochemical reactions of diamond-like carbon (DLC) films during the friction process in different environments and the relationship between tribochemistry and the tribological properties of DLC films. From this, the study proposes strategies to achieve the superlubricity of DLC films through tribochemistry. Finally, challenges and countermeasures in the engineering application of DLC films are discussed.

Abstract
A hydrogenated amorphous carbon (a-C:H) film shows an ultralow friction coefficient (COF, lower than 0.01); however, its wear life is short in vacuum, and the mechanisms are still not well-understood. This study demonstrates the vacuum tribological behaviors of the a-C:H film can be regulated by interfacial activity. The strong interfacial activity induced continuous transfer of carbon from the film to counterface, causing the formation of a porous transfer film and severe wear of the a-C:H film. Interestingly, weak interfacial activity is beneficial to form spherical-like carbon at the sliding interface, which shields the interaction of dangling bonds and contributes to lower COF and wear of film. Notably, the catalytic nature of Au induced perfect graphene nanoscrolls around Au nanoparticles at the sliding interface, achieving ultralong vacuum wear life. This Letter unifies the understanding of vacuum tribological properties of a-C:H film and provides new insight for prolonging the life of carbon films in vacuum.

Abstract
The large-area preparation of excellent lubricating materials with good resistance to leakage and an oxidation atmosphere and ease of replenishment has remained a challenge. Here, inspired by the Nepenthes pitcher slippery surface, we have fabricated multifunctional lubricant-infused surfaces (LISs) via a scalable technique, in which the solid lubricants and the lubricant oil are reciprocally well-combined to overcome their respective weakness. The designed LIS coating exhibits a multiple lubrication ability with a coefficient of friction of 0.022 and ball wear rate of 2.62 × 10-18 m3·N-1·m-1 in air, which are 21 times and three orders of magnitude lower than those of the steel-steel contact under macroscale test conditions (10 N, 5 Hz), respectively. In addition, the outstanding water-repellent and self-cleaning LIS coating enables the resistance to the strong acid or base corrosion even after 30 days of immersion, and the excellent anticorrosion performance during the electrochemical corrosion test. With the exceptional lubrication, multifunctionality performance, and large-scale fabrication capacity, the prepared LIS coating should find potential applications in machines, pipelines, navigation, infrastructures, outdoor equipment, and so on.

Abstract
In this work, the synthesis and characterization of hydrogenated diamond-like carbon (HDLC) nanocomposite thin films with embedded metallic Ag and Cu nanoparticles (NPs) are studied. These nanocomposite films were deposited using a hybrid technique with independent control over the carbon and metal sources. The metallic nanoparticles were directly deposited from the gas phase, avoiding surface diffusion of metal species on the deposition surface. The structural features, surface topography and optical properties of pure and nanocomposite HDLC films are studied and the effect of metal introduction into the carbon matrix is discussed. The interactions between the carbon ion beam and the NPs are considered and it is demonstrated that the nanocomposite HDLC:metal films, especially for Cu NPs, can retain the transparency level of the pure HDLC, by limiting the interactions between metal and carbon during deposition.
