Nano tungsten disulfide, or nano WS2, is a very important additive in the production of high-performance lubricating oil. According to the experts, under the same conditions, the lubricating performance of the base oil added with WS2 nanoparticles is significantly better than the base oil added with conventional WS2 particles, and it has good dispersion stability. In addition, the lubrication performance of nano WS2 is superior to that of nano MoS2.

In other words, adding an appropriate amount of WS2 nanoparticles to the lubricating oil can greatly improve its lubricating performance. For example, it can reduce the friction factor by 20%-50%, and increase the oil film strength by 30%-40%. The experts also introduced that the lubricating oil added with nano tungsten disulfide combines the advantages of fluid lubrication and solid lubrication, and is expected to achieve full lubrication from room temperature to high temperature. Therefore, as an additive, nano tungsten disulfide has broad application prospects in the synthesis of new lubricants.
