Component treatment process and treated gas turbine component

Abstract

A component treatment processes and treated gas turbine components are disclosed. The gas turbine treatment process includes laser-removing coating from a substrate of a turbine component to form laser-induced plasma, spectroscopically analyzing the laser-induced plasma, and discontinuing the laser-removing in response to the spectroscopic analyzing. The treated gas turbine component includes a laser-affected surface, the laser-affected surface having one or both of modified dimensions and modified microstructure due to being exposed to the laser-removing of the coating. The laser-affected surface has a depth corresponding to the laser-removing being discontinued based upon the spectroscopic analyzing of the laser-induced plasma formed from the laser-removing.
