This study investigated the interface temperatures for the sliding friction of three types of pins fabricatedwith thermocouple wires by the suction casting method. Optical microscopy was used to examine the surroundingmaterial state at the bonding interface with the thermocouple wires. Friction tests were performed underdry sliding conditions against stainless steel 304 at nominal stresses of 1.42-4.25 MPa and sliding speeds of 0.5-1.25 m/s. Tribological data were collected using a custom-made pin-on-disk apparatus that measured the interfacetemperature and corresponding friction coefficient. Static tests were performed to demonstrate the functionalityand reliability of the thermocouple wires-combined temperature sensor (TCTS). Each TCTS showed good linearityand sensitivity and very similar response times for the thermocouple and critical temperature during slidingfriction.
