    摘要: A method of removing a coating from the surface of a hole in a metal-based substrate is described. The coating is scored on or near the surface of the hole. The substrate is then treated with a coating-removal solution under conditions suitable for removing the coating without damaging the substrate or any intervening bond layer. The coating is often a zirconia-based thermal barrier coating. In such a case, a caustic solution is used to remove the coating within an autoclave. The substrate can be a component of a turbine engine.
