Whether applying multi-zone coatings or masking complex geometries, LSR™ delivers durable, high-performance results—while reducing environmental impact through water-based binders and low-waste processing.
Yes. Air Plasma Spray (APS) coatings must be removed before any heat treatments or life-extension repairs can be performed. Stripping the APS ensures the base alloy can properly withstand the required temperatures and allows for optimal bonding of the new LSR™ coating.
Whether a mini tip repair is viable depends on the extent of damage, the condition of the parent material, and any existing coatings. A full evaluation is needed to determine the safest and most effective repair approach.
LSR™ is ideal for gas turbine hot-section components made of nickel, cobalt, or iron-based alloys. Both internal and external surfaces can be coated, provided they fit within furnace size limitations for diffusion heat treatment.
LSR™ coatings have been proven to last over 40,000 hours in high-temperature turbine environments, maintaining protective beta-phase aluminum and resisting oxidation and corrosion.
High temperatures and corrosive conditions can degrade turbine components quickly—leading to premature wear, reduced efficiency, and costly downtime. As part of Liburdi’s gas turbine repair services, our thermal barrier coatings are engineered to restore protection and extend part life. Using air plasma spray (APS) for thermal insulation and high velocity oxy-fuel (HVOF) for environmental resistance, we tailor each application to the component’s material, geometry, and operating environment. Our proven compositions—such as NiCrAlY, NiCoCrAlY, CoNiCrAlY, and CoCrAlY—help prevent oxidation and corrosion, improving durability and maintaining turbine performance across demanding service intervals.

APS and HVOF coatings applied during repair improve heat resistance and shield components from corrosive conditions.
Coatings are formulated to match your component's alloy, geometry, and service environment—no generic solutions.
Air Plasma Spray (APS) coatings are essential for protecting hot-section turbine components from extreme heat and thermal fatigue. Applied as part of Liburdi’s repair process, these thermal barrier coatings help extend the life of blades, vanes, combustors, and transitions. Unlike off-the-shelf coatings, our APS solutions are precisely formulated for your specific operating conditions—ensuring better performance, longer intervals between service, and reliable protection where it counts most.
For hot-section turbine components exposed to severe thermal and environmental stress, coating density and adhesion are critical. As part of Liburdi’s repair process, High Velocity Oxy-Fuel (HVOF) coatings provide exceptional protection through tightly bonded, high-density layers. We tailor each formulation—selecting from proven chemistries like NiCrAlY, NiCoCrAlY, CoNiCrAlY, and CoCrAlY—to deliver superior oxidation and corrosion resistance. The result is enhanced durability, longer service life, and more reliable turbine performance in demanding environments.
Generic coatings can lead to premature wear, poor adhesion, and inconsistent results. Liburdi’s coating solutions—applied through our APS and HVOF processes—are precisely engineered to match your component’s material, geometry, and service conditions. Integrated into our repair process, these tailored coatings improve thermal protection, resist corrosion, and help maximize turbine reliability and longevity under real-world operating conditions.
No. While OEM coatings are designed as general-purpose solutions, they often don’t align perfectly with your plant’s specific needs—such as fuel type, environmental conditions, and operating profile. Liburdi evaluates each component through post-service metallurgical analysis to determine if a customized coating would offer better performance. For example, turbines in peaking applications often benefit from specialized coatings that reduce the risk of cracking, corrosion, and airfoil damage—helping extend service life and improve reliability.
Diffusion coatings chemically bond with the base material by penetrating its surface, forming a protective layer that slightly consumes the underlying metal—this can lead to gradual wall thickness reduction over repeated repairs. Overlay coatings, on the other hand, are applied on top of the surface without significant interaction with the base material, offering protection while better preserving part geometry during the repair process.
Metallic coatings are designed to resist oxidation and corrosion, protecting the base material from chemical degradation. Ceramic coatings, on the other hand, provide thermal insulation and are used to reduce heat transfer. In gas turbines, ceramic coatings are always applied over a metallic bond coat to ensure both thermal protection and structural adhesion under high-temperature conditions.
Yes. Hard-facing coatings such as chromium carbide (CrC) are used in various turbine areas to reduce wear and prevent fretting damage, enhancing durability and extending component life.
