A Promising Lubricating Material: Tungsten Disulfide

Tungsten disulfide (WS2) is a promising solid inorganic lubricating material. Graphite and molybdenum disulfide (MoS2) are the earliest and widely used solid lubricating materials. However, WS2 has the tendency to replace molybdenum disulfide or to develop together with molybdenum disulfide.

Tungsten disulfide is a "king of lubrication". This is reflected in its use. So, what are the applications of tungsten disulfide?

1. WS2 powder can be used to lubricate the thread of giant bolts and the valve core of glass valves.

2. WS2 grease - grease added with WS2 powder, can be used for bearing lubrication of high temperature tunnel kiln cars.

3. WS2 oil agent - an oil agent prepared using WS2 powder, corrosion inhibitor, suspension agent and mechanical oil as materials, can be used in metal cutting, drilling and other mechanical processing processes to improve the finish of the processed parts and extend the life of cutting tools and molds.

4. WS2 solid lubricating film - a film-forming agent made up of WS2 powder and epoxy resin or sodium silicate, etc., can be used in institutions that are afraid of contamination or occasionally used for a long time.

5. Solid lubricating parts containing WS2 - self-lubricating parts and components made of WS2 powder, nylon and other engineering plastics, copper, iron and other metal or alloy powders, such as bearings and gears.
