Use of Molybdenum Disulfide


Due to the molybdenum disulfide’s geothermal origin, it offers excellent durability to withstand intense pressure and heat. This is especially true if some amounts of Sulfur are present to interact with iron to form a sulfide layer which works with moly to maintain a lubricating film. Molybdenum disulfide has unique lubricant properties that distinguish it from most solid lubricants. It has a low coefficient of friction which is inherent in a film-forming structure, effective lubricating properties, a robust affinity for metallic surfaces, and very high yield strength. Combining moly and water-soluble sulfides offers lubrication and corrosion prevention in metal-forming materials and cutting fluids.

Similarly, oil-soluble molybdenum-sulfur elements like thiocarbamates and thiophosphates offer engine protection against common wear, corrosion, and oxidation. Because of the weak van der Waals reactions between the layers of sulfur atoms, molybdenum disulfide has a relatively low coefficient of friction. MoS2 is a typical combination of composites and blends that need low friction. Many oils and greases are often used since they can preserve their lubricity, thus extending their use to more critical applications like aircraft engines. Molybdenum disulfide can also be added to plastics to create a composite to enhance strength and reduce friction. Molybdenum disulfide coating (consisting of high-purity moly powder) is a dry film lubricant used on industrial parts to reduce wear and improve the coefficient of friction. Applications of MoS2 coatings include areas requiring an unreactive lubricant that doesn’t trigger reactions when used.
