“…The surface morphology of the as-deposited coatings is shown in Figure 1. The WS x coating does not display any sponge-like and highly porous surface morphology, unlike the ones reported in the literature for pure sputtered TMD coatings [15,26,28]. The deviation from what is most reported in the literature is attributed to the low S/W ratio of the pure coating, which makes the coatings more compact with much less porosity.…”

“…TMDs show excellent sliding performance in a vacuum and poor performance in ambient atmospheres [14,15]. TMDs have been alloyed with different metals [16][17][18][19][20][21][22][23] and non-metals such as C and N [10,[24][25][26][27][28][29][30][31][32], to improve their sliding efficiencies in diverse environments (ambient air at room temperature, ambient air at elevated temperatures, dry N 2 and vacuum). Until now, the most successful approaches include the alloying of TMDs with non-metals (C and N).…”

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.

“…The excellent me- In order to improve the lubrication performance of unit metal nitrides, many studies have shown that the comprehensive protection performance of coatings can be significantly enhanced by doping reinforcement elements into layers. Standard doping features include C, B, Si, Ni, Al, Mo, Y, W, and so on [159][160][161][162][163][164][165]. Doping C element in the coating can refine the grain, reduce the friction coefficient to a certain extent, and improve the wear resistance [166].…”

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.
