Systems and methods for fluoride-ion cleaning of gas turbine components

A method for performing a fluoride-ion cleaning (FIC) process, the method comprising:

• supporting a test sample to be cleaned on a base of a test device;
• coupling a cover of the test device to the base such that the test sample is received within a test volume defined between the base and the cover, the test device defining a metering inlet through which reaction gas from a reaction chamber is receivable in the test volume;
• placing, after coupling the cover of the test device to the base, the test device within an interior volume of the reaction chamber, the reaction chamber defining an inlet for providing the reaction gas to the interior volume, the reaction chamber defining an outlet for exhausting the reaction gas from the interior volume;
• controlling a reaction gas source to provide the reaction gas to the inlet of the reaction chamber for performing a FIC process;
• removing the test sample from the test volume after performing the FIC process;
• and
• determining an efficacy of the FIC process for cleaning a crack in a service part based at least in part on evaluation of the test sample after performing the FIC process.
