WS2 in Oil Timken Data


Nano Lube Technologies is a division of Station Eight, Inc. and is headed up by Bradley Sheldon & Walter Sheldon. Their "Think outside the box" approach to many lubrication and release applications has resulted in identifying markets for WS2 that were previously limited or unserved.

Bradley Sheldon:

Involved with Tungsten based products since 1996, Brad has been developing Nano Lube Technologies with Walter Sheldon to focus on the development of Tungsten Disulfide market areas outside of the spray marketplace.

Michael Ostrowski:

With 30+ years in the tribology field Michael brings a wide range of lubrication knowledge to the company. Michael's work with many large companies to solve lubrication, bearing, & mechanical seal issues for a wide variety applications. Michael's consulting work has been invaluable.

Walter M. Sheldon, Jr.

With over 40 years in the chemical and metallurgical fields Walter formed Nano Lube Technologies with Bradley. He brings a vast knowledge of these fields to creating new uses for Tungsten Disulfide.

Tungsten Disulfide is a crystalline material which looks much like small platelets. When applied to a surface the WS2 material forms a strong molecular bond with it's substrate which is difficult to remove without removing the underlying material.

The crystals themselves are comprised of many molecules of WS2 in hexagonal platelets which are held together with weak Van der Waals bonds that exist between the Sulfur atoms. When force is applied, the individual molecules slip on each other in a process that has been described as trying to walk on a floor full of plates.

Another interesting property of WS2 is that it will not build up on itself. Unlike many other materials, WS2 will not adhere to itself so there is no thickening of the WS2 layer on a friction surface. Because of this if the particle size of the WS2, for example 0.5µ, is applied, then the coating will never exceed 0.5µ.
