Characterization and evaluation of a failed journal bearing: A microstructural study and comparative approach

Key Points

• Failure analysis reveals critical microstructural defects compromising performance and durability.
• Notably, the comparative approach highlights distinct tribological properties between failed and functioning bearings.
• Observational analysis involved visual inspections and microstructural characterization techniques to diagnose failures.
• This study emphasizes the need for better materials and design specifications to enhance bearing reliability.
