Abstract (en)

Methods 200,300 of manufacturing turbine shrouds 10 with an abradable coating 14 that balance the apparently contradictory requirements of high flowpath solidity, low blade tip wear, and good durability in service may include forming an abradable coating on a surface of a coating system to form a substantially smooth flowpath surface. Forming the abradable coating 14 includes forming a relatively porous, smooth abradable coating. The methods may also include machining the abradable coating 14 so as to achieve a substantially smooth flowpath surface. Corresponding turbine shroud (10).
