Boron nitride lubricant

Due to its chemical inertness, oxidation resistance, and high-temperature stability, application of graphitic a-BN as a lubricant is still of increasing importance. The boron nitride lubricant can be included in alloys or ceramics, it can be applied to the surface as a solid layer... [Pg.121]

The applications of hexagonal boron nitride form an important market, mostly as powder for lubricants and additives. Many of these applications are produced by CVD. [Pg.273]

Molybdenum disulhde (M0S2), graphite, hexagonal boron nitride, and boric acid are examples of lamella materials commonly applied as solid lubricants. The self-lubricating nature of the materials results from the lamella crystalline structure that can shear easily to provide low friction. Some of these materials used to be added to oils and greases in powder forms to enhance their lubricity. Attention has been shifted in recent years to the production and use of nanosize particles of M0S2, WS2, and graphite to be dispersed in liquid lubricants, which yields substantial decreases in friction and wear. [Pg.93]

Stronger van der Waals forces hold the sheets in line with each other so that boron nitride is not as good a lubricant as graphite. However, research is being conducted on the use of boron nitride as a high-temperature lubricant because of its chemical stability. [Pg.196]

In view of its similarity to graphite in crystal structure and in the lamellar properties of the crystallites, it was expected that boron nitride would function effectively as a solid lubricant. However, it has been found that the friction of boron nitride is characteristically higher than that of graphite under the same circumstances. D. H. Buckley [82] observed a value of v = 1.0 for the friction of pyrolytic boron nitride in high vacuum (10 torr) at 296 K G. W. Rowe [54] obtained v... [Pg.578]
