Method for stripping gamma-gamma prime coating from gamma-gamma prime alloy

摘要

A method of stripping gamma/gamma prime polycrystalline alloy bond coats from single crystal gamma/gamma prime nickel based superalloys, including the steps of grit blasting (103) followed by the use of hydrochloric acid solutions (105), followed by rinsing (107). The cycle may be repeated several times, with visual inspection (109) between cycles.
