“…Among TiC and TiN films, TiN exhibits a denser microstructure and lower friction and wear in vacuum condition, which could be attributed to the formation of non-lubricating oxides TiO 2 , TiN and TiON at contact area as observed through the XPS. Moreover, the combination of heat and mechanical energy prompt the nitrogen atom on the surface of TiN film to exhibit large number of isolated electrons and electro repulsive force between electron accounts for low friction and wear (Chen et al 2019) [122]. TiN based coatings show low friction and wear at moderate temperatures upto (300 °C) due to formation of oxides and transfer of TiO 2 to the counterface, yet, the high friction and wear is observed for high temperature condition due to crack formation.…”

Space tribology is a very big aspect of space exploration, despite of this fact, there is a dearth of coherent and concise literature available in the field of space tribology. It becomes difficult to understand the tribological behaviour of mating bodies under the extreme environmental circumstances in space due to their potential chemical and physical interactions. The radiation, vacuum, environmental conditions and temperature, are the factors which affects the friction and wear behaviour of mating surfaces and may alter the chemical structure of solid or liquid lubricant. The combination of tribo-physical and tribo-chemical interactions makes the tribological analysis very difficult to understand. The lack of understanding and ignorance might be the reason for not addressing this issue in the past. This review contains the qualitative and quantitative information on the tribological behaviour of different types of liquid lubricants, greases, soft and hard coatings, combined lubrication systems, testing equipment, composites, solid lubricants and alloys developed for space applications.

“…A multi-arc ion plating system (Hauzer Flexicoat 850, Hauzer Techno Coatings BV, The Netherlands) was used to fabricate TiN films. Detailed description of the coating deposition system is illustrated in reference [18] . Two rows of titanium targets (Φ104.8 mm×8 mm, 99.95% purity, three targets each row) were equipped in the inner side of vacuum chamber as the cathode arc sources.…”

“…Additionally, the high temperature tribological test and the vacuum tribological test of the TiN films also have been studied. [7][8][9] Nevertheless, the coefficient of friction of the TiN films is still high (0.5-0.8) for dry friction in the atmosphere environment. 7 As a new type of green and sustainable lubrication, water lubrication is widely used in industrial fields.…”

The lamellar structure and weak interlayer shear force of graphene endow itself potential application value in lubrication fields, while its lubrication performance has been vastly investigated in various fields. However, there are few studies on the composite tribological performance of graphene and ceramic films. In this study, a solid-liquid lubricating system which TiN film slides in graphene aqueous dispersion is developed, aiming to achieve low friction of the TiN ceramic film in macroscale contact. Two kinds of TiN films were obtained by multi-arc ion plating and magnetron sputtering respectively. The tribological test show that the friction coefficient of the TiN film drops when adding graphene aqueous dispersion and varies with the concentrations of graphene. The results indicate that the graphene might act in two ways to achieve low friction of TiN film, which are liquid lubricating effect of solvents and the formation of smooth sliding interface promoted by graphene.
