“…This area has received increasing attention in the past few years and is being actively explored with different hydrocarbons, catalysts [159], environmental conditions and applications like self-lubrication in automotive [129], mechanical components [161], microelectromechanical systems [162], and medical products [163]. The idea has further advanced to treat pre-deposited DLC coatings with carbon enriched lubricants to gain superior lubricity by yielding graphene [164,165] or other by-products [166] through tribo-chemical interaction. Generally, the surface roughness of DLC coatings made with non-conventional methods remains between 5 nm to 20 nm.…”

“…As an engineering approach, the window for achieving superlubricity using DLC and ta-C sliding in self-mating conditions or against steel can be broadened by introducing the type of surface adsorbates that can enhance surface passivation in the tribosystem. In a model study, Khan et al (Khan et al, 2018) proposed an acid treatment route to further enhance the surface hydrophilicity of DLC. Such a treatment combined with the presence of an organic friction modifier (such as alkyl-amine-compounds) effectively passivated the dangling σbonds and reduced the extent of chemical activity and thereby reduced friction.…”

Superlubricity is a terminology often used to describe a sliding regime in which the adhesion leading to friction or resistance to sliding literally vanishes. For improved energy security, environmental sustainability, and a decarbonized economy, achieving superlubric sliding surfaces in moving mechanical systems sounds very exciting, since friction adversely impacts the efficiency, durability, and environmental compatibility of many moving mechanical systems used in industrial sectors. Accordingly, scientists and engineers have been exploring new ways to achieve macroscale superlubricity through the use of advanced materials, coatings, and lubricants for many years. As a result of such concerted efforts, recent developments indicate that with the use of the right kinds of solids, liquids, and gases on or in the vicinity of sliding contact interfaces, one can indeed achieve friction coefficients well below 0.01. The friction coefficient below this threshold is commonly termed the superlubric sliding regime. Hopefully, these developments will foster further research in the field of superlubricity and will ultimately give rise to the industrial scale realization of nearly-frictionless mechanical systems consuming far less energy and causing much-reduced greenhouse gas emissions. This will ultimately have a substantial positive impact on the realization of economically and environmentally viable industrial practices supporting a decarbonized energy future. In this paper, we will provide an overview of recent progress in superlubricity research involving solid, liquid, and gaseous media and discuss the prospects for achieving superlubricity in engineering applications leading to greater efficiency, durability, environmental quality, and hence global sustainability.

“…One of the most efficient ways to increase the corrosion resistance of the inner surfaces of metal pipes is to use hollow-cathode plasma-enhanced chemical vapor deposition (HC-PECVD) technology to deposit diamond-like carbon (DLC) films. DLC films exhibit high hardness, excellent chemical inertness, and no chemical reactions with acid and alkali salts [8][9][10][11][12][13]. By customizing the adhesion to substrates and depositing multiple layers, M. J. Hoque et al [8] created a flawless F-DLC film with minimal surface energy and a Young's modulus akin metals.…”

In order to solve the problem of the corrosion and wear of N80 metal pipelines exposed to corrosive media and abrasive sand during the development of petroleum resources, the proposed solution involves utilizing HC-PECVD technology to deposit a series of multilayer Si-DLC films with varying thicknesses on the inner surfaces of the N80 steel pipes. This investigation systematically explored the microstructure, mechanical properties, tribological features, and corrosion resistance of the multilayer Si-DLC films. Remarkably, after coating the multilayer (Si-DLC)40 film on the inner wall of the N80 tube, the friction coefficient decreased from 0.7~0.75 to 0.2~3, and the wear rate decreased by two orders of magnitude. In addition, the corrosion current decreased by 50%, and the impedance doubled in a 3.5 wt% NaCl solution saturated with CO2. Thus, the multilayer (Si-DLC)40 film on the inner wall of the N80 tube exhibited superior tribological properties and exceptional corrosion resistance. These findings are anticipated to furnish valuable data and technical insights for mitigating corrosion in N80 steel pipes during petroleum exploitation.
