4 Tribological Failures — Erosion Damage to a Stage 17 Compressor Disk [7] Kruth,
mater
A last-stage compressor disk exhibited peculiar findings. Material was locally missing from the disk [8] ee
rim. Almost no deformation was found in the metallographic sections immediately underneath the 2
. : . manuf
subject area. In the case of wear damage or gross deformation this should have been the case. Also, 52/22
there was no evidence of corrosion whatsoever. It was therefore concluded that the failure [9] Hopki
mechanism in this particular case could only be erosion, namely erosion in a flowing medium Journ:
