Use as lubricant
MoS
2
with particle sizes in the range of 1-100 µm is a common dry lubricant. Few alternatives exist that can confer the high lubricity and stability up to 350 °C in oxidizing environments. Sliding friction tests of MoS
2
using a pin on disc tester at low loads (0.1-2 N) give friction coefficient values of <0.1
Molybdenum disulfide is often a component of blends and composites where low friction is sought. 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, MoS
2
forms a composite with improved strength as well as reduced friction. Polymers that have been filled with MoS
2
include nylon (with the trade name Nylatron), Teflon, and Vespel. Self-lubricating composite coatings for high-temperature applications have been developed consisting of molybdenum disulfide and titanium nitride by chemical vapor deposition.
Specific uses
MoS
2
is often used in two-stroke engines; e.g., motorcycle engines. It is also used in CV and universal joints. During the Vietnam War, the molybdenum disulfide product "Dri-Slide" was used to lubricate weapons, although it was supplied from private sources, not the military. MoS
2
-coatings allow bullets easier passage through the rifle barrel causing less barrel fouling allowing the barrel to retain ballistic accuracy much longer.
[8]
This resistance to barrel fouling comes at a cost of slower muzzle velocity with the same load due to a decreased chamber pressure. MoS
2
is applied to bearings in ultra-high vacuum applications up to 10
−9
torr (at -226 to 399°C). The lubricant is applied by burnishing and the excess is wiped from the bearing surface.
