Abstract:
1. A method for regenerating metal oxide coatings on gas turbine engine components, comprising: (a) Defining an exhaust gas recirculation (EGR) loop for said gas turbine engine; (b) Identifying one or more target locations within said EGR loop for monitoring the level of metal oxide degradation over time; (c) Collecting and analyzing data corresponding to said level of metal oxide degradation over time at said target locations; (d) Determining specific ones of said target locations for injection of oxygen into said EGR loop; and (e) Determining the amount of oxygen injection at said specific ones of said target locations sufficient to regenerate said metal oxide coatings to achieve a defined oxide level; (f) Injecting the determined amount of oxygen at said specific locations to regenerate said metal oxide coatings.
