APPLICATION OF NEW-GENERATION SELF-LUBRICATING MATERIALS TO PROVIDE RELIABILITY OF FRICTION UNIT OPERATION IN SPACE VEHICLES

摘要

Investigation results are presented for solid lubricant coatings of molybdenum dise-lenide produced by chemical-thermal treatment of molybdenum in selenium vapors. The interrelation between their properties and structure is considered. The coatings are characterized by stable tribological characteristics under various operation conditions (start-stop regime, air, and vacuum). The examples of their usage in friction joints of space vehicles are presented.
