Tungsten disulfide coating is an extremely slick, dry film lubricant coat. WS2 has an extremely low coefficient of friction of 0.03 — lower than that of teflon, graphite, or molybdenum disulfide. The film is remarkably durable compared to many other lubricant materials and can withstand tremendously high loads of over 300,000 psi.
