Thin-Film Lubrication, Impinged Tungsten Disulfide Coatings

Molecularly bonded Tungsten Disulfide lubricants were originally developed by the U.S. Department of Defense to prevent galling and seizure of metals. As time has gone on, the thin film Tungsten Disulfide coatings have proven to be effective in a wide variety of applications such as: motor parts, pump parts, vanes, pins, rods, bearings, slides, cams, bushings, sprockets, gears, dies, drive train parts, injection molds and saw blades. There is very little dimensional change once the coating is applied, so part dimensions do not have to be re-engineered.
When used with conventional lubricants, thin film Tungsten Disulfide coatings can greatly improve the overall performance and prevent overheating and other problems related to friction.
