Some Characteristics and Applications of Less Common Solid Lubricants

Tungsten diselenide Similar to molybdenum disulphide but better oxidation resistance at high temperatures. ., Nuclear plant [Pg.321]

Niobium diselenide Poorer lubricant than molybdenum disulphide, but better electrical conductivity Electrical contacts [Pg.321]

Graphite fluoride Performance generally similar to molybdenum disulphide. Less adversely affected by moisture, but reported to have shorter life in vacuum [Pg.321]

Lead Not usable in air because oxidation leads to film failure Lubrication of rolling bearings in vacuum [Pg.321]

Silver Friction quite high. Used with calcium fluoride to provide lubrication from 0°C to 900°C [Pg.321]
