“…FT-IR suggests that the dominant form of Si in the film is as a Si-O network with a smaller fraction coming from Si-C bonds thus affecting the coatings microstructure [15]. This trend was also identified by Veres et al [16], in that the presence of oxygen decreased the amount of Si in the carbon matrix.…”

Diamond-like Carbon (DLC) coatings are increasingly used to reduce wear and lower friction in many applications. Doped DLCs are being produced with the goal of further enhancing the friction and wear profile as well as increasing the coating reliability.Silicon is often incorporated into DLC as it is known to affect the sp 2 /sp 3 ratio which in turn can affect the hardness of the film. It can also improve adhesion of the DLC coating to the substrate and lower internal stress.In this study, investigations into the wear behaviour, tribochemistry and oilformulation dependence of Si, O-doped DLC (Si-DLC) were conducted. The oxidative stability of Si-DLC was also examined.Silicon-doped DLC is able to form a protective tribofilm when a fully-formulated lubricant is used. The tribofilm is composed of; S, P, Ca and Zn which are widely recognised as being important to wear reduction.A mechanism of wear repression facilitated by oil additives is proposed.

“…Reported literature precedents for C1s calibrations for various DLC and Si-DLC samples were in agreement on the calibration reference value of 284.4 eV for the main peak. [16,19]. Evaluation of Si2p position and oxygen components were also verified from literature values [16,[20][21][22].…”

“…XPS spectra were calibrated using the main C1s peak component, which is well characterised in the literature. Works in the literature specify spectra of DLC films should be calibrated to the hydrocarbon (CHx) peak at 284.4 eV (19)(20)(21)(22). Calibration shifted the spectrum by 1.2 eV, correcting for charging issues.…”

Diamond-like Carbon coatings are well-known for their excellent wear and friction reducing properties. Novel DLCs are constantly being developed that further these beneficial characteristics; this is often achieved by incorporating a dopant into the microstructure of the DLC. One dopant that is widely used currently in commercial settings, including F1 car engines, is silicon. Si doping can be, to some extent, regarded as a double-edged sword. This is because, whilst it has been reported as being able to reduce friction in certain environments, this usually comes at the cost of far higher wear than the corresponding un-doped DLC. The fundamental aspects of Si-DLC's friction and wear properties are explored herein with the goal of optimising the coating using fundamental tribochemical knowledge.

Diamond-like Nanocomposites (DLN) is a newly member in amorphous carbon (a:C) family. It consists of two or more interpenetrated atomic scale network structure. The amorphous silicon oxide (a:SiO) is incorporated within diamond-like carbon (DLC) matrix i.e. a:CH and both the network is interpenetrated by Si-C bond. Hence, the internal stress of deposited DLN film decreases remarkably compare to DLC. The diamond like properties has come due to
