Tungsten disulfide is used in a variety of applications. It can be used as a lubricant in different industries, especially in the aerospace and automotive industry.
Aside from the lubricity it offers, tungsten disulfide is also non-toxic. It also has a high load-bearing capacity of 300,000 psi. In addition, it has a very low coefficient of friction.
WS2 is a crystalline form of tungsten sulfide. It occurs naturally as a mineral called tungstenite. WS2 has a layered crystal structure. This enables a layer to be maintained in between the particles, helping to increase the lubricity of the underlying surface.
WS2 is a very efficient lubricant, especially for gears and other moving parts. Gears with WS2 tend to run smoother and last longer. Moreover, the coating is compatible with petrochemical oils and synthetic greases.
When applied, WS2 creates a very thin film with a maximum thickness of 0.5 microns. The coating doesn’t require binder applications, since it forms a lubrication layer. Moreover, WS2 can be applied on a variety of surfaces, including steel, aluminum, and magnesium. Besides, it is also effective in vacuums and high-temperature fields.
The lubrication provided by WS2 has a very low friction coefficient, which is very important in the automotive industry. Compared to PTFE and PTFE, it has a lower coefficient of friction.
Another benefit of WS2 is that it doesn’t adhere to itself or to the substrate. This allows for the smooth and easy slipping of the layers.
