“…Over the past few decades, energy and material losses caused by friction and wear in machine elements have given rise to the huge economic and environmental burdens for all countries [1]. Therefore, lots of low-friction materials, coatings, and lubricants have been prepared and discovered to regulate the process of friction and wear in machine elements [2,3]. Among the various materials, diamond-like carbon (DLC) film is considered to be one of the most promising solid lubrication materials for industry applications owing to its outstanding physical, chemical, tribological, and optical properties [4][5][6][7].…”

The purpose of the present work is to probe the friction mechanism of hydrogenated diamond-like carbon (H-DLC) film in air by varying sliding velocity (25-1000 mm/s). Friction tests of Al 2 O 3 ball against H-DLC film were conducted with a rotational ball-on-disk tribometer. As the sliding velocity increases, both the friction coefficient and the surface wear of H-DLC film decrease, reach the minimum values, and then increase in the high sliding velocity region. Based on the observed results, three main friction mechanisms of H-DLC film-namely graphitization mechanism, transfer layer mechanism, and passivation mechanism-are discussed. Raman analysis indicates that the graphitization of worn surface on the H-DLC film has a negligible contribution to the variation of the friction coefficient and the surface wear. The origin of the sliding velocity dependence is due to the synergistic interaction between the graphitized transfer layer formation and the surface passivation. The present study will not only enrich the understanding of friction mechanism of H-DLC films in air, but will also help to promote their practical engineering applications.

“…Then, the hydrogen passivation in vacuum has to change as gas passivation in humid air [6,28,35,38]. The adsorbed water molecules from air can saturate the friction-induced carbon σ -bonds at the sliding interface, which may enhance the adhesive interaction of the transfer layer itself and with the counterface [38,39], thus ensuring a stable transfer layer on the counterface [40,41,42].…”

The friction of hydrogenated diamond-like carbon (H-DLC) films was evaluated under the controlled environments of humid air and vacuum by varying the applied load. In humid air, there is a threshold applied load below which no obvious friction drop occurs and above which the friction decreases to a relatively low level following the running-in process. By contrast, superlubricity can be realized at low applied loads but easily fails at high applied loads under vacuum conditions. Further analysis indicates that the graphitization of the sliding H-DLC surface has a negligible contribution to the sharp drop of friction during the running-in process under both humid air and vacuum conditions. The low friction in humid air and the superlow friction in vacuum are mainly attributed to the formation and stability of the transfer layer on the counterface, which depend on the load and surrounding environment. These results can help us understand the low-friction mechanism of H-DLC film and define optimized working conditions in practical applications, in which the transfer layer can be maintained for a long time under low applied load conditions in vacuum, whereas a high load can benefit the formation of the transfer layer in humid air.

“…Up to now, only a few researchers had been performed on the tribology mechanism of single abrasive wear at the micro-scale [15][16][17][18][19], which hinders the research progress of the abrasive size effect on friction behavior and the abrasive mechanical properties insu cient. The in uence of abrasives size on the abrasive friction behavior and mechanical properties have attracted broad research interests [6,7,15]. The abrasive wear by performing single-asperity scratch with AFM silicon dioxide or tungsten tips were performed to study the in uence of the abrasive size on the abrasive wear at the micro-scale [2].…”

The size of abrasive particle has a great impact on the fundamental friction behavior and mechanical properties of the abrasive during ultra-precision polishing performance. Here, the size effect of the tribological behavior and mechanical properties of CeO2 single abrasive were studied. Experimental results show that the size effect plays a role on coefficient of friction (COF) of each regime in single-asperity sliding friction, especially in ploughing and cutting regimes. The residual depth of the scratch and COF both decrease with the increase of the CeO2 tip radius. These results relate to the mechanical properties of CeO2 nanoparticles. We found that the effective modulus increases with the decrease of abrasive size, which corresponds to the size effect of the single-asperity sliding friction experiment.
