“…A roughness of approximately 0.18 mm70.01 was determined, which is very similar to that of the electroless NiP, whose surface was prepared before deposition. It is well known [5] that DLC films, being structurally amorphous, could closely mimic the original surface roughness of the substrate material. The overall coating thickness of the DLC (a-C:H þ CrC) was determined by means of Calotest (CSEM, Switzerland) measurements and it was found to be of $ 2.2 70.1 μm.…”

“…This conclusion is supported by the results reported by Bhushan [46], who studied the influence of sliding velocity and load on the wear of DLC coatings. Moreover, it has also been shown that the relative humidity could considerably reduce the nominal contact temperature and, consequently, promotes a reduced graphitization [5].…”

“…Another favoured candidate is DLC, which in the past few years has been deposited on light alloys such as Mg, Ti and Al with the aim of enhancing their tribological behaviour, thus increasing their possibility of being used mainly in the aerospace, automotive and military industries, as well as in the manufacture of medical devices [5].…”

is an open access repository that collects the work of Arts et Métiers ParisTech researchers and makes it freely available over the web where possible. Quantitative EPMA analysis carried out on the coated sample cross-section coupled with nanoindentation techniques allowed the identification of the coated system architecture as composed of 4 main layers, with distinct mechanical properties, on top of the aluminium substrate: DLC (a:C-H chromium dopped layer and graded layer of CrC), a newly formed graded layer of CNiPCr, product of the interdifusion during PVD processing, and the NiP coating. The change in the elastic modulus with penetration depth was described by means of an original approach that was developed for its specific application to multilayer coatings.

“…Several dopants, in the form of nano-particles such as metals are incorporated in the DLC coating matrix to reduce the internal stress as well as enhancing the adhesion strength of the coatings [4,5]. The properties of DLC depend significantly on the sp 2 /sp 3 ratio as well as the hydrogen content, which in return, depends on the deposition process and applied parameters [6]. Robertson [5,7] and Grill [8,9] described the deposition methods to grow these films and to improve their mechanical properties.…”

Abstract:Diamond-like carbon (DLC) coatings show extremely good promise for a number of applications in automotive components as they exhibit excellent tribological properties such as low friction and good wear resistance. This can impact on improved fuel economy and durability of the engine components. Much work has been reported on the dry sliding of DLC coatings with less so in lubricated contacts and, as such, there is a need to further understand the tribochemistry of lubricated DLC contacts. Commercially-available oils are normally optimized to work on ferrous surfaces. Previous studies on DLC lubricated contacts have tended to use model oil systems rather than fully formulated lubricants and from this an interesting picture of lubrication mechanisms is emerging. Optimising compatibility between a surface and a set of lubricant additives may lead to excellent durability (wear) as well as increased fuel economy (low friction). In this work, the friction and wear properties of a DLC coating under boundary lubrication conditions have been investigated and the tribological performance compared with that of an uncoated steel system. A pin-on-plate tribotester was used to run the experiments using High speed steel (HSS) M2 grade plates coated with 15 at.% hydrogenated DLC (a-C:15H) sliding against cast iron pins. A Group III mineral base oil, fully synthetic Group IV PAO and four different fully formulated oils were used in this study. Furthermore optical and scanning electron microscopes (SEM) were used to observe the wear scar and to assess the durability of the coatings. Energy-Dispersive X-ray analysis (EDX), X-ray Photoelectron Spectroscopy (XPS) and Raman spectroscopy analyses were performed on the tribofilms to understand the tribochemical interactions between oil additives and the a-C:15H coating.This study show that the durability of the a-C:15H coating strongly depends on the selected additive package in the oils. In addition the effect of detergent, dispersant and antioxidants on the performance of the Molybdenum-based friction modifier (Mo-FM) and ZDDP anti-wear additive were investigated and results are reported in this paper.
