METHOD OF MANUFACTURING A TURBINE SHROUD SEGMENT
Abstract: methods of manufacturing a turbine shroud segment for a gas turbine engine are disclosed. one method involves receiving a turbine shroud segment green part, machining an axial cooling flow passageway in the turbine shroud segment green part, and after the machining of the axial cooling flow passageway, debinding and sintering the machined turbine shroud segment green part. another method involves receiving a turbine shroud segment green part, machining a textured surface on the radially outer surface of the body to obtain a machined turbine shroud segment green part, and after the machining of the textured surface, debinding and sintering the machined turbine shroud segment green part. another method involves injecting powder injection molding material into a mold having cavities defining negatives of features forming a textured surface on the radially outer surface of the body, and debinding and sintering the molded turbine shroud segment green part.
