“…Isaeva et al 36 with a theoretical approach reported that during the sliding of W−S−N coatings nitrogen was released from the contact region in the gaseous form (e.g., N 2 , NO 2 ) without disturbing the formation of the tribo-films. Ju et al 40 recently reported that Mo−S−N coatings showed higher oxidation resistance due to the formation of MoN bonds. Zhang et al 31 reported that the incorporation of a small amount of nitrogen into MoS 2 sputtered films produced a nanocomposite structure, increasing the hardness and reducing the wear.…”

MoS 2 is the most widely used dry lubricant for low friction applications in vacuum environments. However, due to its lamellar nature it exfoliates during sliding, leading to high wear, high coefficient of friction (COF), and low stability. Here, we report the mechanical properties and the vacuum (10 −4 Pa) tribological performance of nitrogen-alloyed transition-metal-dichalcogenide (TMD-N) coatings. The coatings were deposited using a hybrid deposition method, that is, reactive direct current (DC) sputtering of MoS 2 target assisted by an additional plasma source. The tribological tests were performed at relatively low contact stresses to replicate real industrial needs. The interaction between different mating surfaces (coating versus steel, coating versus coating) has been reported. Additionally, the effects of loads on the sliding properties were also studied for coating versus coating interactions. A maximum hardness of 8.9 GPa was measured for the 37 atom % N-alloyed coating. In all mating conditions, the pure MoS 2 coating had COF in the range of 0.1−0.25 and the least specific wear rates were found to be 3.0 × 10 −6 mm 3 /N•m for flat and 2.5 × 10 −6 mm 3 /N•m for cylinder. As compared to MoS 2 coating, the COF and specific wear rates decreased with N additions. The COF was in the range of 0.05−0.1 for Mo−S−N coatings, while coating versus coating displayed the lowest specific wear rates (8.6 × 10 −8 mm 3 /N•m for flat and 4.4 × 10 −8 mm 3 /N•m for cylinder). Finally, the increase in load resulted in a decrease of COF, but an increase in the wear rate was observed. The detailed mechanism behind the behavior of the COF for the different mating conditions was presented and discussed. This work brings some important issues when testing transition metal dichalcogenide-based coatings under low contact stress conditions more appropriate for simulating real service applications.

“…It is well-known that lubricants are widely used to reduce friction and wear in many mechanical systems, which always operate in harsh environment (Trzepiecinński, 2020; Zhang et al , 2020; Diez-Ibarbia et al , 2020). Therefore, lubricants are fairly straightforward to be contaminated, oxidized and even invalidated as a result of their interaction with the friction pairs under various extreme conditions (Bakunin et al , 2004; Ju et al , 2020; Usman, 2020). To resolve those problems, it is indispensable to introduce lubricant additives into the lubricating systems to guarantee the stable performance of lubricants (Ye et al , 2020; Jiang et al , 2020; Zhan et al , 2019; Wang et al , 2019).…”

Purpose This paper aims to contrastively investigate the antioxidant behavior and tribological performance of a novel multifunctional additive (PBT) and dialkyldithiophosphate (ZDDP) in complex lithium grease (CLG). Design/methodology/approach PBT was successfully synthesized through esterification reaction. The antioxidant behavior of PBT and ZDDP was investigated by thermal analysis, and meanwhile, their tribological performance was evaluated by Optimol SRV-IV oscillating reciprocating friction and wear tester (SRV-IV test) and MRS-1J four-ball tester (Four-ball test). Furthermore, their anticorrosion ability was determined by copper strip corrosion test. Findings Four-ball tests showed that the extreme pressure property of PBT was a little inferior to that of ZDDP. Besides, all the other results demonstrated that PBT showed more superior antioxidation stability, friction-reduction and antiwear ability, as well as anticorrosion performance than ZDDP. Originality/value This work provides a study of hindered phenol derivative as a multifunctional additive in lubricant grease, which can contribute to the development of substitution of ZDDP.

“…Compared to the traditional method, the new method promotes a higher dispersive distribution of TiO 2 nanoparticles in the coatings as it avoids the agglomeration of TiO 2 nanoparticles. This TiO 2 -sol enhanced method has been successfully used to prepare Ni, Ag, Ni-B based coatings, etc., without reducing the performances [1][2][3][20][21][22][23][24][25][26]. In our study, a similar method was applied to fabricate copper-tin-zinc (Cu-Sn-Zn, CSZ) based nanocomposite coatings.…”

Cu-Sn-Zn (CSZ) coatings are widely applied in communication devices due to their excellent performance in electrical/thermal conductivity, solderability, and corrosion resistance. Particularly, a novel TiO 2 -sol-enhanced electrodeposition method has been proposed to prepare CSZ-TiO 2 nanocomposite coatings with different volume fractions of TiO 2 -sol. A series of CSZ-TiO 2 nanocomposite coatings were prepared in the current study. The crystal phase, surface morphology, and micro-to nanostructures of sol-enhanced nanocomposite coatings were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Based on the prior research, we studied the microhardness, surface friction behavior, and corrosion behavior of the coatings. Our results indicate that adding 12.5 mL L −1 TiO 2 -sol increased the average microhardness of CSZ coating from 325 to 421 HV and reduced the corrosion rate by 42.8%. Those results reveal that the TiO 2 -sol affected the performance of CSZ coatings depends on the volume added. Additionally, we investigated the effects of TiO 2 -sol volume fraction on the morphology, microhardness, dry sliding wear-resistant capability, and corrosion-resistant capability.
