Characterization of Tribological Materials

Characterization of Tribological Material was written to illustrate the ways in which surface characterization is being used in tribology and the expected future trends. Since tribology is a discipline involving the moving contacts of surfaces, it should not be surprising that surface science must play a role. Although materials used in bearings, gears, sliding seals, brakes, clutches, electrical contacts, and magnetic recording devices have been developed expressly for these applications, the materials are not unique. Most have been adapted from conventional engineering materials. For tribological use, however, parts require some surface characterization. Currently, surface analysis during manufacture includes the determination of roughness, optical properties, surface hardness, and surface coating thickness and bond strength. More sophisticated surface analysis is not, as a rule, used routinely--except for magnetic recording media. Advanced surface analytical techniques are used mostly in the investigation of the mechanisms of friction, lubrication, and wear.
