Nano Tungsten Disulfide Application

Tungsten disulfide is used as solid lubricants, dry film lubricants, self-lubricating composite material, and wherein the nano tungsten disulfide solid lubricant is the best. Mainly because tungsten disulfide nano particles has low friction coefficient, high compressive strength, and with acid erosion resistance, good load performance, non-toxic, wide temperature range, long life and other advantages of lubrication and so it is widely used.
Meanwhile tungsten disulfide nano particles can also be used as an additive to produce high-performance lubricants. After the studies found adding the right amount of tungsten disulfide nano particles in the lubricant can greatly improve the lubricating properties of the lubricant. Under the same conditions, there will improve lubricating properties of adding nanometer WS2 base oil than conventional particles added base oil and has good dispersion stability, friction factor can be reduced by 20% to 50%, the film strength can be increased by 30% ~ 40%, which is far superior lubricating properties than molybdenum disulfide nano particles. With the addition of a lubricant nano particles combines the advantages of solid lubrication and lubrication, which is expected to realize from room temperature to high temperature (over 800 ℃) full lubrication. Therefore, tungsten disulfide nano particles can be used as additives synthesis new lubrication system which has broad application prospects.
