In aerospace, aviation, nuclear power, and other high-tech fields, some essential moving parts must operate under high vacuum, high load, intense radiation, and other conditions. Under such extreme conditions, only solid lubricating materials can meet the lubrication requirements. Traditional material modification methods have problems such as high energy consumption, severe pollution, and narrow scope of application. Plasma modification technology can overcome these shortcomings. This paper focuses on several commonly used plasma preparation techniques for solid lubricating coatings, including plasma chemical heat treatment, physical vapor deposition, plasma immersion ion implantation and deposition, plasma spraying, and plasma electrolytic oxidation. Subsequently, the material systems of metal-based solid lubrication coatings are reviewed: soft metals, oxides, sulfides, nitrides, and carbon-based materials. Finally, found that the development of new solid lubricants, the improvement of existing preparation technology, and the development of new processes are the key development directions in the future.

“…Copper, as a matrix, provides high thermal conductivity and facilitates the efficient dissipation of heat from the friction area of the mating parts. Merging copper and CNTs promises a composite with superior performance due to the CNTs’ unique nanoscale properties [ 6 , 7 , 8 , 9 ]. Despite over three decades of research on their synthesis and processing, their potential is still not being fully utilized, which is crucial for the promise to be accomplished.…”

This paper presents the results of research on the microstructure, mechanical, and tribological properties of Cu/0.5 wt.% MWCNT (multi-walled carbon nanotube) sintered composite materials produced by powder metallurgy. The purpose of this research was to investigate the impact of carbon nanotube modifications on the uniformity of their dispersion and the effectiveness of their bonding with the matrix. The MWCNTs were modified by chemical oxidation. Additionally, a modification of the ingredient mixing method utilizing ultrasonic frequencies was employed. The tests were carried out using scanning electron microscopy (SEM), transmission electron microscopy (TEM), Vickers hardness tests, static compression tests, and wear tests using the pin-on-disc method. Furthermore, mechanical properties and strain distribution analyses of the micro-specimens were conducted using the Micro-Fatigue System (MFS). The implemented modifications had a positive effect on the dispersion of MWCNTs in the copper matrix and on the mechanical and tribological properties of the sinters.

Due to their encouraging results, nanolubricants have been revolutionary in the field of lubrication. The degree, to which the new material may improve the tribology, energy savings, and durability, is a crucial consideration for any new additive to a conventional lubricant. The results of the earlier research on carbon, metal, metal oxide, and their composites and hybrid nanolubricants as well as their effects on tribology, are summarized in this review paper. The most popular measuring methodologies, the tribology results for lubricants with an oil base, biodegradable base, and a water base, as well as the reasons that explain these tribological advancements, are all included in this study. Finally, prospects for more study in this area are emphasized.
