WS2 Solid Lubricant

1.Introduction Solid lubricant is a material which decreases friction and abrasion by forming thin lubrication coating layer. Solid lubricant can be used even on extreme conditions such as very high or low temperature or vacuum, where liquid lubricant can not be used. WS2 solid lubricant has excellent oxidation resistance compared to other lubricants such as Graphite, MoS2. Moreover, it has high lubricity under the conditions of severe temp. and load. The application field of WS2 solid lubricant is being widen gradually. 2.The comparison of solid lubricant 3.The characteristic of WS2 solid lubricant Lubrication Feature Increased durability and wear resistance by forming thin lubrication coating layer. High lubricity compared with Graphite, MoS2 Keeping lubrication effect at low temp(-273°C) and high temp(450°C),   under oxidation atmosphere and in vacuum up to 1,200°C Physical & ChemicalFeature Excellent erosion and corrosion resistances Auxiliary effect when mixed with grease or oil Availability of spray dry coating at room temp. on steel, ceramics and plastic etc. Increasing lubricity in frictional parts by spray dry coating 4.Performance test of solid lubricant Frictional coef. of drying coated WS2 Low frictional coef., high lubricating effect in vacuum Comparison of MoS2 solid lubricant Good lubrication characteristic (WS2 > phosphate + MoS2) 5.Application Fields of WS2 solid lubrication 6.NANO WS2 solid lubricant NW-10 WS2 solid lubricant powder with excellent lubricating effect at high temp.(Registered 2 Korean patents) NW-50 WS2 solid lubricant spray can with convenient application.(Registered the Practical New Device) NW-C Forming thin(under 0.5µm) lubricating coating layer with increasing durability (Applying for a patent) Piston CathoderayTube Mold Mold Parts Cylindrical Piston
