Tungsten Disulfide Lubricant

The industrial production department has put forward more and more strict requirements on the performance of lubricating oil (grease).

Ordinary equipment is often replaced by low-performance lubricants (grease) instead of high-performance products, causing equipment damage or lubricating oil (grease) consumption, therefore, it is of great significance to accelerate the research and development of high temperature lubricating oil (grease) to meet the needs of the domestic market.

Tungsten sulfide is a compound of tungsten and sulfur, and it is a new kind of solid lubricant with excellent performance, not only suitable for general lubrication conditions, but also for high temperature, high pressure, high vacuum, high load, radiation and corrosive medium working environment, the magnetic properties of WS2 clusters are not only lubricated but also adsorbed on the metal surface during lubrication. A layer of nano protective lubricating membrane is formed on the metal surface.

Tungsten sulfide has a very small coefficient of friction (about 0.03), it can be used as additive in metal powder to improve the adhesion of metal powder under high speed friction condition and to obtain stable friction coefficient. Nanometer WS2 has excellent oxidation resistance, can be used as additive in lubricating oil (grease), it can effectively improve the lubricating oil (grease) properties of extreme pressure and anti-wear performance, it is not only good lubricating performance, and long service life.

The purity of tungsten sulfide is still very expensive, especially nano tungsten sulfide. In China, in addition to aerospace, tungsten sulfide has been widely applied in various industrial machinery operation in high temperature, the most mainstream collocation is that use tungsten sulfide ultrafine powder as additives in lithium complex greases, both can control costs, and to effect.
