A technique used for improving the performance and durability of aircraft turbine engines by flowing abrasive media through critical components is described. The process is abrasive only where the flow is restricted: the extrusion area (the process is also known as extrusion honing). Process parameters including extrusion pressure and the volume of flow are presented, and the tooling and media are covered. The abrasive grains are mostly made of silicon carbide, although boron carbide, aluminum oxide, and diamond may also be used. Some abrasive-flow machining applications in aerospace involve removal of the thermal recast layer in the lasered cooling holes of blades and disks, deburring fuel spray nozzles, and polishing cast surfaces of blades, compressor wheels, and impellers. 6 refs.
