Caption

Scanning electron micrograph of scratches on 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. These raised rings are gradually scratched and 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: x2000 at 8x10 inch size.
