• the present invention relates to coatings for friction reduction and the prevention of corrosion. More particularly, the present invention relates to polymer carried lubrication and corrosion protection coatings suited for extreme environments.
• Wheel lubrication is known in the art. Archeological evidence shows the use of tallow for wheel lubrication dating prior to 1400 B.C. The study of lubrication and frictional coefficients may be considered to have started in the late 1880's in England when Tower produced his studies on railroad car journal bearings in 1885. Since then, numerous artisans have engaged in the endeavor of finding lubricants and coatings suited to optimize the advantageous aspects of friction reduction in various environments.
• Lubrication coatings fall typically into two broad categories, fluid film lubrication and dry film lubrication. Each of these prior art methods of providing lubrication suffer from their own respective set of drawbacks.
• fluid film lubrication the load on moving surfaces is supported entirely by the fluid between the opposing surfaces. Pressure on the film develops through the motion of the surfaces, this motion then in turn delivers the lubricant into a converging wedge-shaped zone.
• the behavior of the moving surfaces is totally dependent on the fluidity or viscous behavior of the lubricant. Film pressure and power loss are dependent on the viscosity of the lubricant as well as the configuration of the moving surfaces, and lubricant shear strength.
• Dry lubricants present their own set of drawbacks. Typically, dry lubricants are applied as thin coatings or as particulate materials to reduce wear and friction of moving surfaces. As noted by Levy, these films or particulate materials may comprise or incorporate solid or particulate carbon-graphite, lead babbitt, bronze, aluminum, polyethylene or polytetrafluoroethylene solid or articulate materials in a binder where the film or particulates are adhered to one or both of the moving surfaces.
• dry lubricant film or particulates is controlled to some degree by the bfnfaeT where' sol ⁇ cT ' ⁇ f 1' particulate lubricants are employed as well as conditions of use such as the load, surface temperatures generated during use, speed of the moving surfaces, hardening, fatigue, welding, recrystallization, oxidation and hydrolysis.
• dry lubricants typically are not able to provide any scrub resistance or weathering resistance, thereby greatly reducing their usefulness in any event.
• Some embodiments of the present invention overcome the practical problems described above and offer additional advantages as well. Some embodiments of the present invention solve various of the above-described drawbacks by providing coatings providing friction reduction and corrosion protection.

• Lubricants such as greases and oils must be replenished on to frequent a schedule and may fail from either too high a frequency of use or strong weathering conditions.
• Dry film lubricants while appropriate from a frequency of use standpoint do not tend to protect equipment sufficiently from corrosion due because they are typically difficult to apply in such a manner that they fully cover surfaces using in service application processes as described below. Additionally dry film lubricants do not posses a scrub resistance so that when forces are produced in directions other than those where a dry film lubricant material provides appropriate slip planes (basal plane in graphite) they are easily removed and rendered ineffective.
