Relatively few investigations have been presented on thermal contact conductance (h c) at elevated temperatures, although such information is important for applications in manufacturing, material processing, and other high-temperature applications. In order to experimentally study the effects of these parameters at elevated temperatures, an experimental apparatus which includes a vacuum system, test apparatus and data acquisition system has been designed and fabricated to measure h c. Experiments were conducted on carbon steel specimens with a controlled degree of surface characteristics at an average interface temperature of 500-650 K, and an average contact pressure in the range of 0.5-9 MPa. An increase in the contact pressure increased h c, to a maximum of about 20 kW m -2 K -1, and a hysteresis in h c was observed during the pressure cycle. Temperature, however, had little effect on h c, for the range examined.
