“…Graphite-like carbon (GLC) films, as amorphous carbon films, have numerous applications in machinery, tooling, automotive, electronics, optics, and aerospace because of their self-lubricating properties, adaptable tribological behavior in various environments, and high chemical stability. − However, GLC films contain certain internal stresses and are weakly bonded to the metal substrate, making them susceptible to spalling under external loads in mechanical and automotive systems. − The restricted load-bearing capacity of single GLC films on metal surfaces limits their wide applications. Over the past few decades, many approaches have been explored to mitigate this problem.…”

This study reports a novel process for the fabrication of highperformance graphite-like carbon (GLC) films on nitrided substrates through successive steps in a plasma nitriding system. Unlike films fabricated via conventional dual treatments (nitriding + film deposition), here-fabricated GLC films were grown on the surface of nitrided steel via a catalytic reaction. A transition zone having a nanocrystalline and amorphous structure was observed at the interface between the nitrided substrate and GLC films, which increased the durability of GLC films because this structure enhanced the adhesion of GLC films on the nitrided substrate, improving resistance to spallation and wear. Experimental study and first-principles calculations showed that the Fe 3 N phase had a stronger catalytic effect on GLC films than the Fe 4 N phase, and GLC films grown on the nitrided layer dominated by Fe 3 N were thicker with stronger adhesion and excellent frictional and wear properties compared with GLC films grown on the nitrided layer dominated by Fe 4 N because of the beneficial structure formed at the interface. This study reports a simple and inexpensive method to fabricate a dual layer containing high-performance GLC films via a catalytic growth and interface matching mechanism.

“…According to the content of sp 3 (diamond-like) and sp 2 (graphite-like) bonds, the amorphous carbon films mainly contain diamond-like carbon film (DLC) and graphite-like carbon film [1][2][3][4][5][6][7]. Various technologies are used to deposit the film, such as magnetron sputtering deposition, plasma enhanced deposition, pulsed laser deposition, multi-arc ion plating deposition and so forth [8][9][10][11][12][13]. By comparison, the GLC films prepared through magnetron sputtering technology are considered to be a potential lubrication application material because of their low COF, chemical inertness and corrosion resistant in humid or water environment [14].…”

The pattern of micropore with various diameters (0, 0.5, 1.5 and 5 μm) on the surface of single crystal silicon was obtained through laser treatment and then the graphite-like carbon (GLC) film was deposited on these substrates through magnetron sputtering technology. The effect of micropore diameter on tribological performance of GLC film under air and aqueous environments was systematically investigated. The results indicated that the micropore diameter and test environment greatly affected the tribological behavior of GLC film. The friction coefficient (COF) and wear loss of GLC film were significantly improved in aqueous environment compared with in air. This was attributed to the formation of aqueous molecular film, which could obstruct the immediate contact between GLC film and counterpart. Meanwhile, the anti-wear ability of GLC film in aqueous environment strengthened firstly and then weakened as the micropore diameter increased. When the micropore diameter was 1.5 μm, the GLC film displayed the lowest wear rate of 0.32×10 −8 mm 3 Nm −1 in aqueous environment, which was 67.65%, 46.08% and 26.67% lower than the micropore diameters of 0, 0.5 and 5 μm, respectively. This was due to the synergistic effect of surface roughness and lubricant (graphitized particles and aqueous medium) captured by micropores.

“…1 Thus, there is an urgent need to solve the friction and corrosion problems for mechanical equipment. [2][3][4][5][6][7] Many kinds of protective coatings can be achieved through anodizing, chemical treatment, plasma electrolytic oxidation duplex-treating, electrochemical deposition, CVD and PVD, although their service life and protective effect are different. Among them, CrN coatings prepared by PVD technology are broadly applied to boost the surface property of friction parts, which attributed to its ideal mechanical, anticorrosion and anti-wear abilities.…”
