“…The different type of chemical structure can be obtained by using different types of deposition technique. To convert the carbon into sp 3 hybridization phase, high energy vacuum deposition processes are required, the use of different energy intensity results in the formation of different carbonaceous structure (Shi et al 2022) [103]. The low energy process like magnetron sputtering forms film closer to sp 2 structure carbon film, which is also referred as a-C amorphous film.…”

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.

“…The space industry has great economic and scientific value (Orleanski, 2019), but high returns come with high risks. Space equipment is affected by many dangerous factors such as vacuum, cryogenic and radiation in space (Shi et al , 2022); the vacuum environment is a factor that cannot be ignored in the development of space equipment. To ensure the smooth implementation of space projects, it is necessary to conduct environmental simulation tests on the ground for each part or the whole space equipment, and the test indicators involve many aspects such as mechanical properties, material properties and electronic circuit stability (Ding et al , 2022).…”

Purpose The purpose of this paper is to test and analyze the friction torque of double-row angular contact ball bearings under vacuum or ordinary pressure environment, horizontal or upright installation mode, and different rotational speeds, and to provide theoretical bases for the development of aerospace equipment. Design/methodology/approach The experiments were carried out to investigate the effects of vacuum or ordinary pressure environment, horizontal or upright installation mode and different rotational speeds on bearing friction torque. To explore the relationship between working conditions and bearing friction torque, firstly, based on the generation source of friction torque, the test principle was determined, a test system was developed and the reliability of data was verified. Secondly, the friction torque of bearing was tested, and the values under various working conditions were obtained. Finally, this paper compared and discussed the test results. Findings The test results show that the friction torque value of vacuum environment horizontal installation condition is the largest at different rotational speeds, and the rotational speed has the most significant influence on the friction torque. Originality/value The friction torque test system of double-row angular contact ball bearing under vacuum environment was designed and built. The influence rules of vacuum or ordinary pressure environment, horizontal or upright installation mode and different rotational speeds on bearing friction torque were obtained.

“…Among the technologies which have been used to fabricate the F-DLC coating, the plasma-enhanced chemical vapor deposition (PECVD) is more popular than other methods, since the properties of the coating can be adjusted by changing the process parameters such as power, gas flow rate and chemical composition of the precursor. Moreover, it is versatile technology for scaling up the process for industrial applications from selfcleaning windows to solar cell components [22].…”
