False-colour scanning electron micrograph of the surface of a lubricating film of molybdenum disulphide from a dry film anti-scuffing aerosol spray. The spray contains the lubricant,a volatile organic solvent and a small amount of bonding resin. The solvent quickly evaporates,leaving a layer of randomly- dried rings of molybdenum disulphide (as seen here). These raised rings are gradually abraded with use,slowly smearing out to produce a thin film. Dry film lubricants have several advantages over oils; they do not pick up dust,can be used to higher temperatures and do not tend to contaminate other parts. Magnification: x130 at 35mm size | |
