Tungsten Disulfide Overview
Fluidized tungsten is a small gray crystal or powder with metallic luster, belonging to the hexagonal crystal system, with semiconductor and diamagnetic properties. The natural mineral is tungsten ore. The layered structure is easily dissociated and has lubricating properties similar to graphite.
Tungsten disulfide characteristics
Low coefficient of friction
Tungsten disulfide (WS2) has a dynamic coefficient of 0.030 and a static coefficient of 0.070 to 0.090. Pressure, surface finish and surface hardness can affect these results. Extensive real-time, real-life wear and tear changes little over time unless severe overload conditions are introduced.
chemical stability
Tungsten disulfide (WS2) is inert, non-toxic and non-corrosive. WS2 can be applied to all stable metal substrates. It is unaffected by most solvents, refined fuels and chlorinated solvents. It is attacked by fluorine, sulfuric and hydrofluoric acids and hot caustic solutions. WS2 is corrosion resistant, but it does not inhibit the effects of corrosion on inherently low resistance materials.
compatibility
WS2 is successfully used in petrochemical oils and greases, synthetic oils, silicone lubricants and hydraulic oils. It has an affinity for lubricants and works hard to maintain a hydrodynamic layer.
Application of tungsten disulfide
Tungsten disulfide can be used as a lubricant, and its performance is better than that of molybdenum disulfide, with a lower coefficient of friction and higher compressive strength. Stand alone equipment for high temperature, high pressure, high speed, high load and operation in chemically active media. Lubricants formulated with other materials for forging and stamping can prolong die life and improve product finish. Filler material configured with PTFE and Nylon for the manufacture of self-lubricating parts. In addition, tungsten disulfide can also be used as a catalyst in the petrochemical industry, which has the advantage of cracking tungsten disulfide. (WS2) or tungsten disulfide is a very smooth dry film friction coating. WS2 is extremely low, at 0.03, lower than PTFE, graphite or molybdenum disulfide (MoS2). It has unmatched performance in lubricity, non-stick, low friction, wear life and size ratings compared to many other WS2s. It has a wide range of applications in transistors, sensors, photocatalysis, electronic equipment and other fields. Tungsten disulfide powder has good solubility in water and ethanol.
WS2 is an excellent release material for plastic molds, extrusion dies and other release applications.
WS2 can save hydraulic oil and can also be used with petrochemical oil, grease, synthetic oil, silicone oil valve and hydraulic oil. It has affinity for the liquid layer and keeps the liquid layer. surface, thereby further improving the lubrication effect. Small parts can be coated without tolerance issues when the thickness is less than 1 micron.
WS2 is also a fairly inert and non-toxic material that has been used in medical devices and food processing applications.
WS2 replaces customer substrates with high-speed processing at ambient temperatures. It will not make the substrate continuous or warp.
WS2 can be used alone or in combination with our PVD hardcoats for increased durability, high performance, stable and reliable catalytic activity, and long service life.
