Several research projects have been completed as part of an ongoing programme of work into solid-lubricated bearings for high-temperature space operation. Testing of bearings indicated that MoS2 lubrication is effective at high temperature, but highl

Ball bearings in space mechanisms are subjected to vibration during launch which can lead to a temporary loss of contact between the balls and the raceway. On re-establishing contact the transient high contact stresses which arise may cause damage to

Currently, sputtered molybdenum disulphide is an established coating in the field of space applications. However, when used in air, molybdenum disulphide loses much of its lubricating power, thus preventing in-air ground testing. In this work, the tr

In a series of experiments, the friction coefficients and durability of steel substrates coated with thin films of molybdenum disulphide have been studied, for various values of the substrate roughness and the film thickness. The results are interpre
