Space environmental effects on MoS2 and diamond-like carbon lubricating films: Atomic oxygen-induced erosion and its effect on tribological properties

Microstructure and tribological properties of MoS2+Zr composite coatings in high humidity environment

“…MoS 2 has a hexagonal layered structure, and weak Van der Waals bonding of layers [1][2][3], which make MoS 2 can easily slide under low shear stresses associated with a low friction coefficient [4][5][6]. Sputter MoS 2 coating as a popular and important solid lubricant coating has been widely used in the aerospace field due to its ultra-low friction coefficient (about 0.001) in high vacuum and dry air environment [7][8][9][10].…”

Tribological Characteries of DLC film in Sliding Contacts under Differ-ent Lubrication Conditions

“…To achieve better lubricity in demanding tribological applications, more and more attention be paid on solid lubrication coatings used with liquid lubricants simultaneously in recent two decades [14][15][16][17], but knowledge of the tribological performance of the coatings in lubricated conditions is still quite limited.…”

Changes in the structure and tribological property of Ag film by LEO space environment exposure

“…Therefore, for the space materials used in the LEO, the AO effect must be took into discreet consideration. In the past several decades, the AO effect has been studied to reveal the change mechanism of the structure and performances of the materials [3][4][5][6][7][8][9][10][11][12] and further to develop more suitable materials for space application.…”
