What are Dry Film Lubricants and why are they used for?

Dry Film Lubricants, also known as solid film lubricants, are defined as one or more solids used between two surfaces in relative motion for the purpose of lowering friction or reducing wear. Dry lubricant can also prevent galling, cold welding and fretting.

Dry Film Lubricants are best utilized in extreme environments where typical hydrocarbon based lubricants such as oil and grease are not effective. These include very high or low temperatures, extreme pressure, vacuum applications and in hard to access maintenance applications where long term lubrication is beneficial.

Which are the most commonly used and reliable dry film lubricants?

The most common dry film lubricants are:

  • Molybdenum Disulfide (MoS2)
  • Tungsten Disulfide (WS2)

These, along with graphite are dichalcogenides and have a lamellar lattice structure.

Structure and Properties in Brief

Dry Lubricant in the dichalcogenide family has weak Van Der Waals forces and strong ionic bonds in the basal planes. As an example, Dry Lubricant is like a series of vertically stacked plates (basal planes) supported by long wobbly legs (weak Van Der Waals force). Under applied lateral force, the legs collapse and the plates slip out of place.

The strong ionic bond between the plates (basal plane) forces the slippage to be perpendicular to the basal planes. In essence, the friction is not determined by metal to metal contact or even metal to coating contact but instead, when dry lubricant coating applied to one or both surfaces, friction is determined within the lubricant itself, particle to particle.

Who is the industry-best dry film lubricant coating service provider?

Dry lubricant can be applied in a variety of ways. Micro Surface Corporation in San Jose, CA is a leading dry film lubricant supplier and also the well-known in the application of WS2 per Process SL-39 (DOD-L-85645A Type I / AMS2530) and MoS2 in accordance with MIL-PRF-46010 and AS5272 and AMS2526.
