    摘要: Extreme pressure additives may be added to greases to improve their lubricating properties, particularly to decrease friction and wear of parts that are exposed to very high pressures. Molybdenum disulfide is frequently used as an extreme pressure additive. However, molybdenum disulfide is expensive, has limited availability, and may have adverse environmental effects. This invention discloses an extreme pressure additive and grease formulation where the amount of molybdenum disulfide is reduced through the addition of calcium carbonate while the performance characteristics of the grease are maintained or improved. The extreme pressure additive may comprise about 20% molybdenum sulfide and about 80% calcium carbonate, by weight.
