Tungsten disulfide is applied for lubricating aviation equipment in the form of dry film lubricant. Even in the harsh interstellar environment, WS2 dry film lubricant can provide excellent lubrication effect to reduce the wear of moving parts and extend the service life of parts.

This is because tungsten disulfide has excellent dispersion stability, friction resistance and wear resistance, as well as high extreme pressure resistance and oxidation resistance, so that it is suitable for lubrication under harsh conditions such as high temperature, high pressure, high vacuum, high load, high speed, and ultra-low temperature. In addition, WS2 nano particles can fill the depressions on the friction surface, can fill in the wear parts in time, and have a self-repairing ding, so that the friction surface is always in a relatively flat state, and the anti-friction and anti-wear ability of the dual surface is improved. In fact, WS2 is used for lubricating aviation equipment long ago.
