Abstract: Thermal imaging may be used for obtaining measurements of a tribological testing apparatus including a contact temperature. For example a method of calculating a contact temperature may include: introducing a testing sample into a contact zone of a tribological testing apparatus; engaging a testing operation of the tribological testing apparatus; measuring a contact emission of a testing surface of the tribological testing apparatus with an infrared camera; and calculating a contact temperature of the testing sample in the contact zone from the contact emission; wherein the tribological testing apparatus has a carbon coating on the testing surface of the contact zone, wherein the carbon coating has a first infrared emissivity, wherein the testing sample has a second infrared emissivity, and wherein the first infrared emissivity is within +/−20% of the second infrared emissivity.
