An apparatus is described for bringing a rider specimen and a slider specimen into continuous sliding contact so that significant temperatures at the interface are achievable. The design is such that the flow fields of heat in the specimens would be at most two-dimensional, i.e., within engineering approximations; this fact makes possible the measurement of temperatures of the specimens without disrupting the flow fields of heat. Typical data are presented of speed, normal load, frictional resistance, and temperatures at strategic locations on the specimens. Using the heat-equation solutions obtained previously for the configurations concerned, contact-surface temperature distributions of both specimens are calculated from experimental data. Results give the pointwise, temperature juncture condition at the interface.
