Abstract
An in situ friction, wear and electrical contact resistance pinon-plate system has been installed in a scanning Auger microprobe. Friction coefficients and contact resistance were measured continuously as wear progressed. The composition and topography of a wear progressed. The composition and topography of a wear track wear measured intermittently without exposure to contaminating environments or removal of the pin from the track. Experiments were completed with control of gaseous contaminants in the ambient. For a palladium alloy pin (ASTM B540) sliding on a gold alloy plate (ASTM B541), three stages of wear have been identified, and these are: (1) prow formation on the pin, (2) work hardening and roughening of the wear track, and (3) rider wear. The composition of the prow was essentially that of plate material during the first two stages of wear but was a mixture of pin and plate materials during the third stage of wear. In a helium ambient high contact resistance occurred concomitantly with a transition to the third stage of wear.
