Removal of Coatings from Jet Engine Components with Ultrahigh-Pressure Waterjets

This presentation discusses the application of clean, ultrahigh-pressure waterjets to remove coatings from jet engine components during refurbishment and manufacture.

Accurately applied, clean ultrahigh-pressure waterjets have been used and accepted for the removal of a number of coatings used in jet engines. In this paper the successfully removed coatings and related base metals are presented. Environmental and process advantages over existing methods are also covered. A coatings removal system that will remove a wide range of coatings from many different jet engine parts is introduced.
