? 2022 The AuthorsAcicular grindable thermocouples represent an interesting and prospective technique of temperature measurements at sliding contacts. This study aimed at the investigation of their reliability and accuracy as applied to the friction materials of various classes in contact with steel. The tests were conducted on a pin-on-disc tribometer under stationary and transient regimes. The experimental results were validated by comparing the temperature data obtained by the acicular thermocouple, conventional thermocouples and infrared thermography. It was found that the measurements conducted with the acicular thermocouples are test-retest reliable for copper and a brake pads material, whereas they are not reliable for a polyamide. The temperature rise measured with the acicular thermocouple deviates from that registered by infrared thermography by 7–15% for copper and 10–19% for the brake pads material.
