Rejuvenation Heat Treatments
FSR®Full Solution Rejuvenation®heat treatment cycles, developed and introduced by Liburdi since 1980 to restore the alloy microstructure and the original creep strength, have been successfully applied to over 40,000 blades over the past 20 years.
Specialized Welding Systems
High performance blades suffer oxidation metal loss at the tips due to high operating temperatures. Specialized, oxidation resistant weld alloys are now used for repair which provide superior oxidation resistance compared to the original blade alloy. Laser and MicroPlasma welding systems developed by Liburdi for the aero industry are being used to successfully weld these alloys.
Internal and External Coating Systems
Internal coatings have limited life, and must be effectively removed and replaced in order to carry out the advanced repairs.
High Strength Powder Metallurgy Repair Process
Vanes and Nozzle segments are prone to cracking initiated during start/stop cycles. To extend the ultimate service life and time between repairs, Liburdi employs our patented, LPMTM Powder Metallurgy process for high strength repairs which are proven in service to be superior compared to welding.
