Investigation of crystalline and amorphous MoS 2 based coatings: Towards developing new coatings for space applications

Tribological properties of 3 types of MoS2 additives in different base greases

“…Molybdenum disulfide (MoS 2 ) is a well‐known layered solid lubricant with a hexagonal structure. MoS 2 has been widely applied as a lubricating additive in base oils, greases, plastics, and coatings . Thus, to improve the lubricating performance of MoS 2 is very important for industrial applications.…”

“…MoS 2 has been widely applied as a lubricating additive in base oils, [1][2][3] greases, 4-6 plastics, 7,8 and coatings. 9,10 Thus, to improve the lubricating performance of MoS 2 is very important for industrial applications. Recently, some methods have been developed to improve the lubricating performance of MoS 2 , involving reducing the size and controlling the morphologies of MoS 2 particles.…”

Work of Adhesion Measurements of MoS2 Dry Lubricated 440C Stainless Steel Tribological Contacts

“…[1][2][3][4][5] Moreover, tribological contacts are closed and impossible to observe without changing contact conditions by, for example, using transparent materials such as glass and sapphire. Although experimental observation has demonstrated the existence of solid and gaseous flows within the contact, [6][7][8][9][16][17][18] observation inside contacts between engineering materials such as steel remains challenging. The third body concept is a promising model for lubrication in various environments.…”

“…[10][11][12][13][14][15] It suggests that a thin layer, called the third body, is progressively formed inside the contact to accommodate velocities and transfer loads between the bodies initially in contact, the first bodies. Although experimental observation has demonstrated the existence of solid and gaseous flows within the contact, [6][7][8][9][16][17][18] observation inside contacts between engineering materials such as steel remains challenging. Numerical modeling based on discontinuous mechanics, for example Molecular Dynamics (MD) at the nano-scale [19,20] and Discrete Element Method (DEM) at the micro-scale, [20][21][22][23] are promising frameworks for artificially looking inside a contact of interest to understand and predict the tribological behavior of real lubricated mechanisms.…”
