Abstract: Molybdenum disulfide is a solid lubricant which has a wide usage area in lubrication industry. One of the Major usage areas of molybdenum disulfide is an extreme pressure improving agent. In this study we have been investigated the performance effects of particle size of molybdenum disulfide on lithium soap greases and calcium complex soap greases. We have been applied 1%, 3% and 5% of fine powder molybdenum disulfide and nano molybdenum disulfide on lithium soap and calcium sulfonate complex greases. We have been evaluated the potential usage of nano molybdenum disulfide on grease formulations as an extreme pressure additive. Finally we have been evaluated and reported performance results of nano molybdenum disulfide compared to fine powder molybdenum disulfide.
Key Words: Molybdenum disulfide, calcium sulfonate, grease, nanoparticle, lithium
