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.
Keywords :
Journal bearing , bearing failure , fretting , sulfur attack , fatigue.
