Tungsten disulfide Properties
Low friction
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-life wear show little to no change over time unless extreme overload conditions are applied.
Chemistry stability
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.
Compatibility
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 keep the fluid power level.
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 much lower than other lubricants. It also has very low exhaust characteristics. Because of its high resistance to heat, tungsten fluoride is ideal for fitting bolts into studs or shafts in exhaust systems on all makes and models of cars.
What’s tungsten disulfide for?
Petroleum catalyst:
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 friction coefficient ranges between 0.01-0.03, with a compressive strength of up to 2100MPa. This lubricant has many advantages, including a high lubrication temperature, long life span, low friction coefficient, excellent acid and alkali resistance as well as good corrosion resistance. It is also used for transportation of chemical active media and high temperature equipment.
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 and rapid electron transfer rates. These properties can help improve energy density as well as structural stability of the electrode materials.
Chip transistors
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 to lubricating oil.
It has been shown that the addition of appropriate amounts of WS2 Nanoparticles to lubricating fluid can significantly improve its lubrication performance, decrease the friction coefficient by 20%-50%, increase oil film strength and reduce the oil’s oil-water ratio by 30%-40%. The lubrication performance of WS2 nanoparticles is superior to that of Nano-MoS2.
