Tungsten disulfide Properties
The dynamic coefficient (WS2) of tungsten dioxide is 0.030. While the static coefficient ranges from 0.070 to 0.90, it is close. The results can be affected by pressure, surface finish, and surface hardness. The results of extensive, continuous, real-time wear show little to no change over time unless extreme overload conditions are applied.
Tungsten diulfide (WS2) has a non-toxic, inert nature and is also non-corrosive. You can apply WS2 to any stable metal substrate. It does not react to most solvents. The fluorine and sulfuric acid, hydrofluoric acid, as well hot caustic solutions can cause erosion. While WS2 has a high resistance to corrosion, it is not able to prevent corrosion from inherently weak materials.
The WS2 can be used to make petrochemical oil and greases, synthetic oils as well as hydraulic oils. This oil has a natural affinity for lubricants. It strives to preserve the fluid power layer.
High operating temperatures
WS2 operates at temperatures ranging from -460 F to 1200 F in normal air and 2400F in vacuum. There is an 825 degree F oxidation threshold, which is quite low compared to other lubricants. It also has very low exhaust characteristics. Because of its high resistance to heat, tungsten fluoride is an ideal material for bolts/studs and shafts used in exhaust systems.
What’s tungsten disulfide for?
Due to its outstanding cracking ability, high catalytic activities, and extended service life, WS2 can also be used as catalysts for hydrogenation, desulfurization polymerization, reforming and hydroxylation.
A solid lubricant
The compressive strength of WS2 can be as high as 2100MPa and its friction coefficient is anywhere from 0.01 to 0.03. This lubricant has many advantages, including a high lubrication temperature, high compressive strength, good resistance to acid and alkali, and low friction. It is also used for transporting equipment and chemical active media.
As energy storage electrode material:
WS2 refers to a type layered material that is interconnected by WMurS and van der Waals forces between layers. The distance between the layers is medium. This gives it good thermochemical stability, high storage performance, fast electron transfer rates, and excellent energy density.
Low-dimensional semiconductor materials made from transition metals such as WS2 can be used to make semiconductor devices capable of more data processing and storage.
A high-performance additive for lubricating oil.
It has been shown that adding the appropriate amount of WS2 Nanoparticles to the Lubricating Oil can significantly improve its lubrication performance, decrease the friction coefficient by 20%-50%, increase oil film strength and reduce the friction coefficient of up to 30%-40%. The lubrication performance of WS2 nanoparticles is superior to that of Nano-MoS2.
