“…The Me-DLC coatings were deposited on the substrate using an hybrid deposition process composed of plasma enhanced chemical vapor deposition (PECVD) from acetylene/argon gas mixture and DC magnetron sputtering of metal target. The details of hybrid deposition process were reported elsewhere [8,13]. The mixture of C 2 H 2 and Argon was introduced in the chamber, and the pressure was maintained at 1.33 Pa during the deposition process.…”

“…In addition, Ag film is known as a practical solid lubricant for aerospace applications [2]. In recent years, we have reported on the tribological properties of metal/DLC nanocomposite coatings (Me-DLC) [3][4][5][6][7][8]. Especially, copper/DLC nanocomposite (Cu-DLC) and silver/DLC nanocomposite (Ag-DLC) coatings exhibited good electrical conductivity.…”

Formation processes of metal-rich tribofilm on the counterface during sliding against metal/diamondlike-carbon nanocomposite coatings have been investigate. The hybridization between DLC matrix and Cu or Ag provides good electric conductivity to solid lubricant films. Metal-rich tribofilms are formed on the counterface of both Cu-DLC and Ag-DLC during sliding, which is important factor to obtain excellent tribological performance as well as good electric conductivity. Such tribofilms are almost pure Cu and Ag. The origin of the tribofilm is the metal clusters in the Me-DLC, and the adhered Cu and Ag clusters on the counterfaces are possibly sintered and refined during iterative plastic deformation in the frictional interface which generates high pressure and high shear rate.

“…The deposition of a-C/DLC films have a rather high residual compressive stress which depends on the deposition method. The limit for practical application of a-C/DLC film high stress is caused by the weakening of film bonding to the substrate; thus, when reaching some critical thickness, the stress can result in the delamination of film from the substrate [19,20].…”

The aim of this chapter is to report the results on synthesis DLC thin films and carbon nanocomposites by the versatile nanofabrication method based on plasma entitled thermionic vacuum Arc TVA . TV" technology is based on the localized ignition of the arc plasma in vacuum conditions. "mong thin film coating methods by vacuum deposition techniques with high purity, low roughness, and good adhesion on the substrates, TVA is one of the major suitable methods to become a powerful coating technology. Two or three different TV" discharges can be ignited simultaneously in the same chamber for multi-material processing using TV" and separate power supplies. These TV" discharges are localized and do not interfere with each other. Simultaneous two or three TV" discharges were already used for the production of alloy/composite of various materials. This is due to the high versatility concerning the configuration of experimental arrangements, taking into account the number of electron guns, symmetry of the electrodes, relative position of the anode versus cathode, and also the huge opportunity to combine the materials to be deposited bi-and multi-layers, nanocomposites, or alloys in order to have specific applications. This chapter presents the comparative results concerning the surface-free energy information processing, the reflective index, the hardness, and the morphology to provide a coherent description of the diamond-like carbon films and carbon nanocomposites synthesized by thermionic vacuum arc TV" and related configurations where Me = "g, "l, Cu, Ni, and Ti: binary composites CMe, C-Si and ternary composites C+Si+Me . The results include reports on the distribution in size, surface, geometry, and dispersion of the nanosized constituents, tailoring and understanding the role of interfaces between structurally or chemically dissimilar phases on bulk properties, as well as the study of physical properties of nanocomposites structural, chemical, mechanical, tribological .

“…Ag, Ti, Al, Ir, and Si) into those coatings [13][14][15][16][17][18][19]. Friction coefficients of less than 0.10 or even 0.01 have been observed in ambient air with Ag-DLC [13], Ti-DLC [14], Al-DLC [15], TiSi-C:H [16], and a-C:Si:Al coatings [17]. Particularly, the low friction coefficient (about 0.06) of Al-DLC coating (Al of 2.3 at.%) in ambient air (relative humidity of 35 ± 5%RH) is due to the formation of a continuous and compact carbon tribo-film other than a metallic tribo-film on the mating ball surface [17].…”
