Liburdi researchers with McGill and University of Toronto studied laser deposition of a Rene 142–MERL 72 superalloy blend using the Liburdi LAWS1000 system. The 2021 paper reports practising squealer-tip, tip-cap and full-tip repair at Liburdi and compares deposited material with conventional repair alloys.
Technical detail
Core features
Laser directed-energy deposition with coaxial powder delivery
Published testing on Haynes 230 substrates
Tensile, stress-rupture and cyclic oxidation characterization
Reported squealer-tip, tip-cap and full-tip repair practice
Laser directed energy deposition
Blade tip repair
Superalloy
Use & integration
Recorded applications
Turbine blade-tip restoration
Qualification of repair materials for hot-section components
These describe the reviewed application scope, not confirmed deployments, released requirements or procurement eligibility.
Evidence of maturity
Peer-reviewed 2021 material testing and reported repair practice. Tensile/creep performance exceeded Rene 80 under studied conditions, with lower elevated-temperature elongation. Component interfaces and broader creep studies remained follow-up work.
Commercial availability
Published repair practice establishes more than a concept; the paper does not identify a current fleet-qualified parts list or general delivery approval.
Integration and verification
