ABSTRACT:
A method for determining a useful life applied to a coating on a surface of a component coupled to a rotatable member of a rotary machine. The method includes directing a laser across a surface of the component while the rotatable member remains coupled within an assembled rotary machine and measuring radiation emitted from the surface of the component.
