Abstract:
This paper describes a chemical immersion process capable of removing ceramic thermal barrier coatings, high temperature oxidation resistant coatings, and, nickel-aluminide bond coat materials from gas turbine engine components typically found in commercial and military jet engines. This process was originally developed to remove thermal barrier coatings from JT-8D combustion chambers for commercial aircraft. Since then, the process has been utilized to remove a variety of MCrAIY coatings from commercial and military aircraft engines.
