“…[31][32][33] In this study, the tribological properties for as-fabricated coatings in dry ambient air are investigated. Most of researchers reported that the tribological properties of Si doped DLC films were sensitivity influenced by Si content in ambient air; moreover, the low friction and wear were easily achieved by high Si content.…”

In this paper, the amorphous carbon-based coatings containing F and Si (a-C:F:Si) are successfully fabricated using a plane hollow cathode plasma-enhanced chemical vapor deposition method. The results show that the mechanical properties of these coatings, such as hardness, elastic modulus, friction and wear, are closely affected by the content of F and Si. We systematically examine the microstructure and composition of these coatings using SEM, XPS, AFM and Raman for understanding of the underlying frictional mechanism.

“…A similar behaviour was observed elsewhere for WS 2 /DLC/WC coatings showing a huge friction coefficient difference when sliding in humid or dry air [10]; the friction behaviour was attributed to the alternative formation of a WS 2 -rich or a C-rich layer during the cyclic change of the environment from dry to humid, respectively. Another concept presented in literature for the TMD+C composite coatings deals with nanolayered structured coatings [12], where tungsten disulphide and carbon layers form a "super-lattice" film (the thickness of layers is in nanometre scale). The performance of such films was only moderate.…”

In this paper, results on the tribological behaviour of nanocomposite coatings composed by nanoplatelets of transition metal dichalcogenides (TMD) immersed in a C-rich amorphous matrix will be presented. It will be shown that this microstructure will allow low friction coefficients in wide range of surrounding environments, since TMD platelets are re-oriented in the C-matrix as a consequence of the mechanical energy liberated in the sliding contact. In this case, the oxidation of the TMD material is avoided due to the protection achieved by the C matrix. Examples of TMD-C coatings of the W-S-C and MoSe-C systems will be presented and discussed. After tribological characterization of the coatings in different environments under different loading conditions experimental evidence of the wear mechanisms will be given by cross section transmission electron microscopy, Raman spectroscopy and Auger electron spectroscopy.

“…It showed a reduction of the wear rate after irradiation, which could be related to the increase of hardness. Noshiro et al [21] has studied the friction properties of sulfide/DLC coating with a nanocomposite or -layered structure on Si wafer, which shows better tribological properties than DLC film. Previous work has focused only on either the composite MoS 2 /DLC coating on metals or DLC and MoS 2 separately as coating on elastomers.…”

Abstract:The potential of the combination of hard and soft coating on elastomers was investigated. Diamond-like carbon (DLC), molybdenum disulfide (MoS 2 ) and composite coatings of these two materials with various DLC/MoS 2 ratios were deposited on four elastomeric substrates by means of the magnetron sputtering method. The microstructures, surface energy of the coatings, and substrates were characterized by scanning electron microscopy (SEM) and contact angle, respectively. The chemical composition was identified by X-ray Photoelectron Spectroscopy (XPS). A ball on disc configuration was used as the model test, which was performed under dry and lubricated conditions. Based on the results from the model tests, the best coating was selected for each substrate and subsequently verified in component-like test. There is not one coating that is optimal for all substrates. Many factors can affect the coatings performance. The topography and the rigidity of the substrates are the key factors. However, the adhesion between coatings and substrates, and also the coating processes, can impact significantly on the coatings performance.
