Lubricant

MoS2 with particle sizes in the range of 1–100 µm is a common dry lubricant.

Few alternatives exist that confer high lubricity and stability at up to 350 °C in oxidizing environments.

Sliding friction tests of MoS2 using a pin on disc tester at low loads (0.1–2 N) give friction coefficient values of <0.1.

MoS2 is often a component of blends and composites that require low friction. A variety of oils and greases are used, because they retain their lubricity even in cases of almost complete oil loss, thus finding a use in critical applications such as aircraft engines.

When added to plastics, MoS2 forms a composite with improved strength as well as reduced friction.

Polymers filled with MoS2 include nylon (with the trade name Nylatron), Teflon and Vespel. Self-lubricating composite coatings for high-temperature applications consist of molybdenum disulfide and titanium nitride, using chemical vapor deposition.

Examples of applications of MoS2-based lubricants include two-stroke engines (e.g., motorcycle engines), bicycle coaster brakes, automotive CV and universal joints, ski waxes, and even bullets.
