“…One should bear in mind that higher hydrophobicity of the surface is usually related to a higher chemical stability. Actually, in our experiments SFE of NBR elastomers decreased by 9% after DLC deposition [77]. For hydrogenated HNBR elastomer, the variations in the hydrophobicity after DLC coatings were statistically insignificant.…”

“…Despite the small variations observed in the surface chemical composition, DLC-coated elastomers presented better tribological performance reflected in a significant reduction in the coefficient of friction (COF) and friction noise [77]. Also, water CA increased for NBR after DLC deposition ( Figure 10) indicating the increase in the hydrophobic character of NBR elastomer surfaces after DLC deposition.…”

“…Nakahigashi et al [4] reported a strong reduction of CoF after deposition of the DLC film when compared to unprotected rubbers, although the lowest CoF reached under their low-load tribotest condition was around~0.7. In contrast, Martínez et al [5] studied much stronger conditions (10 and 40 N load), reaching CoFs of 0.44 and 0.23 as lowest values, respectively.…”

“…This leads to a modification of the surface energy. On the other hand, from the perspective of the material, the surface energy of elastomer substrates [53], DLC and MoS2 are also different. These two factors together affect the difference of the surface energy after coating.…”

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.
