Abstract
A method for repairing a damaged tip of a turbine engine member, for example a tip of a high temperature operating turbine blade, having a designed length and an environmental resistant coating at least on an outer wall of the member and extending at least onto the tip, includes removing the damaged tip without first removing coating, on a wall adjacent the tip. This provides a preform end surface to which is bonded a replacement tip material having a second length greater than the designed length. Then a portion of the replacement tip material is removed to provide the member with a repaired member tip and of substantially the designed length while retaining the coating on the wall adjacent the repaired tip.
