Abstract
A method of measuring temperature of a part heated during a heating process includes applying a non-reactive coating at a first temperature; heating the part, and thereby the coating thereon, to a second temperature greater than the first temperature; and measuring a temperature distribution of the part by measuring infrared light emitted from the heated coating using a thermal imaging device calibrated to the known emissivity of the coating. The coating is at least partially opaque and having a known emissivity of infrared light and conducts thermal energy from the underlying part.
