“…As a medium-temperature lubricant, Ag is the most widely used. Ag has a facecentered cubic structure that is prone to intergranular slip [125][126][127]. Ag can significantly improve the plasticity and toughness of coatings/films by refining grain size, thereby improving the tribological properties of layers [128][129][130].…”

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.

“…To comprehensively assess the mechanical performance of the TiN/TiSiN gradient multilayer coatings, the relationships of H and E, and H/E* and H 3 /E* 2 are presented in Figure 8. In [3,24,[60][61][62][63][64][65][66][67][68][69][70][71][72], various MeSiN monolayer coatings containing Si and Me 1 N/Me 2 N (Me: Ti, Al, Cr, TiAl, etc.) multilayer coatings revealed excellent mechanical properties, e.g., the TiSiN/AlTiN coating had the highest H of 42 GPa and the E of 345 GPa, as well as the highest H/E* and H 3 /E* 2 of 0.15 and 0.52 GPa, respectively.…”

Hard coatings, such as transition metal nitrides, have been widely applied to improve the mechanical properties and tribological performance of cutting tools. The coatings in various multilayered or gradient structures have been designed to meet the demands of more severe service environments and more precise processing requirements. In this work, TiN/TiSiN coatings in several gradient and multilayered structures were deposited on cemented carbides by cathodic arc ion plating using Ti and TiSi alloy targets. The modulation period (Λ) of the multilayer gradually varies with thickness, ranging from 6 to 46 nm. The gradient multilayer coatings consist of a nanocrystalline-amorphous composite with compact growth. The coating with a modulation period first increasing and then decreasing has the highest hardness of 38 GPa, and the maximum residual compressive stress of −2.71 GPa, as well as the minimum coefficient of friction (COF) and wear rate. Gradient and multilayer structures moderate the brittleness caused by the presence of amorphous SiNx phase and optimize the mechanical properties and tribological performances of the coatings.

“…These studies rendered fruitful results in unveiling many ambiguities faced during the analysis of the performance of materials at high temperatures. Recently, annealing studies have been widely conducted for dry lubricant thin coatings to understand the high temperature stability and oxidation resistance [5][6][7][8]. During high-temperature sliding of dry-lubricant coatings, there are still many unanswered questions related to the reasons behind low/high friction coefficient (COF), enhanced crystallisation, oxidation behaviour, Materials 2022, 15, 4088 2 of 11 diffusion of lubricant phase to the surface, the effect of temperatures on life cycle, etc.…”

Alloyed-transition metal dichalcogenide (TMD) coatings have been under investigation as multi-environment lubricants for the past few decades. These coatings display very low coefficient of friction properties at elevated temperatures. Studies on the annealing of these low-friction coatings are missing in the literature. For the first time, in this study, the annealing of the W-S-N dry lubricant coatings was carried out to study its effects on the composition, morphology, crystal structure and hardness of the coatings. The W-S-N coatings were deposited by direct current (DC) reactive magnetron sputtering. The analysis was carried out for as-deposited, 200 °C and 400 °C annealed coatings. The as-deposited coatings have N content in the range of 0–25.5 at. %. The coatings are compact and the densification increased with the increase in N-alloying. All the coatings are crystalline except the highest N-alloyed coating which is X-ray amorphous. A maximum hardness of 8.0 GPa was measured for the coating alloyed with 23 at. % N. Annealing did not affect the composition and morphology of the coatings, while some variations were observed in their crystal structure and hardness. The maximum hardness increased from 8 GPa to 9.2 GPa after 400 °C annealing of the 23 at. % N-alloyed coating.
