###### Abstract
The results showed that when the coated sample was refuted against \(\mathcal{O}3\) mm 316 stainless steel balls in fresh 5W-30 oil under a load of 10 N, the coefficient of friction (COF) was approximately 0.13. In degraded oil, it varied between 0.11 and 0.20. The coatings showed excellent wear resistance, with no visible damage observed on the worn tracks. On the other hand, as the performance of the coatings is highly dependent on the substrate material, variations in the substrate properties could affect the adhesion strength and overall effectiveness of the coating. Yet, in general, it is still observed that the advantages of using carbon-based structures as coatings outweigh the disadvantages. [PERSON] et al. [21] claimed that, when the surface is treated with boronized functionalization and lubricated with a 1 wt% GO nanosheet water-based additive, an ultralow friction state with a coefficient of friction of 0.03 could be achieved. [PERSON] and [PERSON] [22] observed the electromagnetic interference shielding effectiveness of nitrogen-doped carbon (CN) thin films deposited on an aluminum/polyethylene terephthalate substrate. They achieved an electromagnetic shielding efficiency of up to 74.1 dB at 10.11 GHz when the CN film with 3 sccm of N\({}_{2}\) was deposited on the Ti/Al/polyethylene terephthalate substrate. In their experimental investigation, [PERSON] and [PERSON] [5] sought to ascertain the effect of N\({}_{2}\) incorporation in DLC coatings on the formation of carbon bonds and to gain a comprehensive understanding of the tribological characteristics of the coating by conducting thorough research on the coated substrates. CH\({}_{4}\) gas was used as a carbon source and N\({}_{2}\) was utilized to crystallize the carbon bonds in DLC/NCD form by adjusting the flow rates (CH\({}_{4}\)/N\({}_{2}\) plasma) through the ECR-CVD process at a bias voltage of \(-600\) V. The ideal flow rates for wear and friction resistance were determined to be 8 sccm of N\({}_{2}\) and 6.05 sccm of CH\({}_{4}\), providing a very low average coefficient of friction of 0.025, a hardness increment of up to 42% and a roughness reduction of 30%. In general, the adhesion and uniform distribution of carbon-based coatings on rough surfaces are issues that need attention. Based on this, this study presents a variety of carbon-based structures (rGO, GO, CNT, nanodiamond) successfully deposited on metal surface via the ECR-CVD plasma technique and a specially designed microcontroller substrate rotating mechanism that allows variable plasma angle and duration. To the authors' knowledge, the aforementioned studies and other related research in the literature include the production of only one type of carbon-based structures generally deposited on very smooth surfaces (very low roughness), its impacts on various scientific fields and its possible applications. Another issue in previous studies is that the coated surface has a regular geometry, such as a square or rectangle. For surfaces with high curvature (such as the ring sample in this study), an Arduino-controlled mechanism has been developed to ensure that all the surfaces that will come into physical contact within the mechanism could be uniformly coated. In this study, the novel methods used during the coating process via the specially designed ECR-CVD plasma set-up provided the simultaneous deposition of several carbon-based structures with superior features, even on curved and very rough steel substrates. Moreover, a comprehensive friction-wear analysis was conducted on the \"Uncoated Sample (US)\", \"Sample coated with only Carbon (SC)\", and \"Sample coated with Carbon in the presence of Nitrogen (SCN)\" to determine the mechanical strength improvement to the carbon coating under dry friction conditions. Therefore, it is believed that this study will be beneficial in terms of filling a gap in the literature and will be a good guide for many studies on carbon-based structures and industrial applications.
