Long service hours at high temperatures in corrosive environments (e.g., Cl- contamination) cause surface cracking. Cooling Passage Issues: Gasturb Crack
Cracks often start in cooling holes where stress concentration is high. 🛠️ Detecting and Managing Turbine Cracks Timely maintenance is key. Regular hot gas path inspections (HGP) are essential, utilizing: Borescope Inspections Direct visualization of combustion chambers and HPT blades. Dye Penetrant Testing: For surface-breaking cracks. Ultrasonic Testing (UT) For finding internal flaws. Eddy Current Testing:
one of the most critical threats to turbine reliability and safety. Restoring parts through skilled welding, followed by stress
Utilizing Thermal Barrier Coatings (TBC) to reduce thermal load, though thickness must be managed to prevent spallation. Weld Repair:
Using stitching or "dog-bone" inserts to fix casing cracks in place. Analytical Monitoring: Using software like Ultrasonic Testing (UT) For finding internal flaws
High-speed rotation and pressure forces create vibration-induced fatigue. Overheating/Hot Streaks:
