All About Specialty Coatings and Lubricants

1. What are solid film lubricants (SFLs)? They are thin films of resin that bind lubricating powders such as MoS2 (molybdenum disulfide), graphite, or PTFE to a surface.

2. How do they work? They prevent surface-to-surface contact, reducing friction and wear between mating surfaces. Each lubricant powder has different properties. MoS2 provides higher load carrying and corrosion protection than graphite, while graphite provides higher temperature stability and better electrical conductivity. PTFE provides the highest level of corrosion protection, release, and functionality for lighter load applications.

3. How do solid film lubricants produce low friction? They have exceptional low resistance to shear and slip easily… like a deck of new cards.

4. Are these films thick? No. Most are applied to a dry film thickness of 0.0002 to 0.0005 inches.

5. How are solid film lubricants applied? They are sprayed, dipped, dip/spun, tumble sprayed, or brushed onto a properly pretreated surface. Some require thermal curing and others are ready to use after air drying.

6. Where are SFLs applied? If only one surface of mating surfaces is to be coated, it is generally best to coat the surface with the greatest area. Camshafts, bearings, guns, weapons, pistons, valves, connectors, fasteners, and slides are examples. Typical situations where solid film lubricants should be used include:

•On heavily loaded equipment susceptible to galling and seizing…particularly aluminum and titanium.

•On inaccessible or concealed components where maintenance of conventional “wet” lubes are not practical or possible.

•On equipment that may not be compatible with fuel,solvents,grease, or oils.

•In place of liquid lubricants that can migrate and contaminate adjacent parts.

•Where dust or other airborne debris may impair machine operation.

•Where operating temperatures exceed the range of fluid lubricants.

•Where fretting corrosion occurs(solid film lubricants can often delay the onset of corrosion beyond the expected life of the part).

 

7. What are the frictional properties of SFLs?

•As load increases,the coefficient of friction(µ)decreases(to a point), to as low as 0.02 under extreme loads on hard surfaces.

•The kinetic(ordynamic)coefficient of friction is slightly lower than the static coefficient.

•The coefficient of friction is affected by the hardness of the surface to which the lubricant is applied, decreasing for hard surfaces and increasing for soft ones.

•The coefficient of friction is lower for rotating motion than for oscillating motion.

•The purpose of the film is to prevent surface-to-surface contact. The rule is: For the lowest friction and longest wear, use the hardest metals consistent with good design.

•If it is necessary to choose between applying the lubricant to either surface in a hard/soft bearing system, the lubricant should be applied to the softer material.

•The coefficient of friction of a solid film lubricant is independent of temperature within the coating’s recommended range.

•Thecoefficientoffrictionofcrystallinelubricants,likeMoS2, WS2, and graphite, will always decrease during burnishing.

•Ingeneral,coating both surfaces will provide greater service life but may reduce load-carrying capacity due to plastic deformation of the thicker dry film thickness layer.
