“…Aluminum alloys used in aerospace applications are susceptible to fretting wear, especially in critical working environments. To address this issue, Lin et al [ 227 ] developed a duplex coating consisting of multiple combined solid lubricants, also known as a chameleon, on a 6082 Al alloy undergoing fretting tests. The developed coating efficiently reduced fretting COF and enhanced the wear resistance of the base alloy.…”

Plasma electrolytic oxidation (PEO) is a novel surface treatment process to produce thick, dense metal oxide coatings, especially on light metals, primarily to improve their wear and corrosion resistance. The coating manufactured from the PEO process is relatively superior to normal anodic oxidation. It is widely employed in the fields of mechanical, petrochemical, and biomedical industries, to name a few. Several investigations have been carried out to study the coating performance developed through the PEO process in the past. This review attempts to summarize and explain some of the fundamental aspects of the PEO process, mechanism of coating formation, the processing conditions that impact the process, the main characteristics of the process, the microstructures evolved in the coating, the mechanical and tribological properties of the coating, and the influence of environmental conditions on the coating process. Recently, the PEO process has also been employed to produce nanocomposite coatings by incorporating nanoparticles in the electrolyte. This review also narrates some of the recent developments in the field of nanocomposite coatings with examples and their applications. Additionally, some of the applications of the PEO coatings have been demonstrated. Moreover, the significance of the PEO process, its current trends, and its scope of future work are highlighted.

“…Besides, to further explain the sharp increase of COF values for the Sb 2 O 3 −MoS 2 composite coating as the temperature was increased to 400 °C, Raman analyses of this coating after the tribological tests at different temperatures were also conducted, as shown in Figure S15. Compared with the peak strength of MoS 2 (at approximately 145, 377, and 404 cm −1 ) 35,46 and Sb 2 O 3 (at approximately 189, 253, and 449 cm −1 ) 34 inside the wear track tested at temperatures of 100, 200, and 300 °C, that obtained at temperatures of RT and 400 °C decreased sharply. This is consistent with the friction test results shown in Figure 2 that the Sb 2 O 3 −MoS 2 composite coating failed after 1200 revolutions at RT and 400 °C.…”

“…They attributed the performance to the preservation of discharged fresh MoS 2 and the crack inhibition of Sb 2 O 3 layers. Subsequently, Zabinski et al, 33 Shirani et al, 34 Lin et al, 35 and Scharf et al 36 39−42 It was previously reported that the high-temperature superlubricity phenomenon accomplished in a burnished MSH/C−Sb 2 O 3 coating on a nickel superalloy substrate could be attributed to the formation of an easy shearing silicate-containing carbon film on the surface of the coating, which was tribochemically activated during sliding. 43 In this study, a MoS 2 lubricant was introduced as a replacement to the carbon lubricating phase, and the resulting synergistic superlubricity with the MSH nanomaterial and Sb 2 O 3 was explored in an open-air and hightemperature system.…”

“…Based on the degradation mechanisms, most efforts to reduce the friction and wear and increase the lifetime of MoS 2 -based coatings at high temperatures have focused on the alteration of MoS 2 surfaces for reduced oxygen and water adsorption. Binary or ternary doping materials, such as metals (titanium, aluminum, nickel, gold, chromium, vanadium, zirconium, and lead − ), carbon-based materials, , antimony trioxide (Sb 2 O 3 ), ,− and others, , have been proven to increase the coating density and hardness. Further, they act as thermal and oxygen diffusion barriers to improve the antioxidant characteristics of MoS 2 -based coating.…”

Expanding the low-friction temperature range of molybdenum disulfide-based coatings has been a topic of intense research interest. This paper introduces a coating concept, enabling achieving macroscale superlubricity, or near-zero friction, when exposed to open-air and high-temperature sliding conditions. This low-friction composite coating with a thickness of approximately 150−250 nm was accomplished by uniformly burnishing hydrothermally synthesized lamellate magnesium silicate hydroxide with an average diameter of 50 nm and an average thickness of 10 nm, molybdenum disulfide, and antimony trioxide powders onto a copper substrate. The tribological experiments performed in an open-air environment revealed that with the increase of testing temperature up to 200 °C or above (up to 300 or 400 °C), the coefficient of friction of the composite coating rapidly decreases and finally reaches the superlubricity state (the coefficient of friction is lower than 0.01). This intriguing superlubricity performance is attributed to the synergistic characteristics of lubricating antimony trioxide, molybdenum disulfide, and magnesium silicate hydroxide phases, enabling easy shearing of the film at high-temperature conditions. The results offer an approach for designing a solid lubricant solution for tribological applications.

Rubbers are widely used in various fields as the important sealing materials, such as window seal, door seal, valve, pump seal, etc. The fretting wear behavior of rubbers has an important effect on their sealing performance. This paper presents an experimental study on the fretting wear behavior of rubbers against the steel ball under air conditions (room temperature at 20 ± 2 °C and humidity at 40%). Three kinds of rubbers, including EPDM (ethylene propylene diene monomer), FPM (fluororubber), and NBR (nitrile–butadiene rubber), are considered in experiments. The sphere-on-flat contact pattern is used as the contact model. The influences of the displacement amplitude, normal force, frequency, and rubber hardness on the fretting wear behavior are discussed in detail. White light profiler and scanning electron microscope (SEM) are used to analyze the wear mechanism of the rubber surface. The fretting wear performances of three rubbers are compared by considering the effect of the displacement amplitude, normal force, frequency, and rubber hardness. The results show that NBR has the most stable friction coefficient and the best wear resistance among the three rubbers.
