Sliding Friction Characteristics of MAC Greases under Vacuum Condition

Even though solid lubricants or low-volatile greases are used for lubrication of mechanical equipments in space satellites, the life of grease is longer than that of solid lubricants because of the hydrodynamic effects and replenishment. New grease using multiply alkylated cyclopentane (MAC) as base...
