Abstract:
This paper presents a failure analysis of journal bearings used in GE-F9 gas turbines. Detailed studies including visual examination, optical microscopy, scanning electron microscopy, XRD and oil analysis were performed to determine the root causes of failure. Based on the results, it was determined that fretting, sulfur attack and fatigue were the main causes of failure.
