Abstract
A method for estimating an operating temperature of component in turbo machinery includes providing body detachably affixed to component, operating machinery, stopping operation of machinery, and removing body. The method includes obtaining concentration profile by determining final concentration of at least one species in first material and in second material, and determining a transient concentration of at least one species between first material and second material. The method includes determining an operating temperature by correlating concentration profile to corresponding operating temperature for system. A system including body is also provided. Body includes at least one species, a first material having a starting first concentration of the species, a second material arranged to permit migration of the species from first material to second material. Species migrates from first material to second material during operation of turbo machinery allowing body to estimate temperature during operation.
