At the core of every LSR™ aluminide coating is a beta-phase aluminide layer that forms a stable, adherent oxide barrier—critical for resisting oxidation and hot corrosion in gas turbine hot-section components. Unlike standard slurry coatings, LSR™ Al and LSR™ SiAl formulations are enhanced with silicon and chromium to improve phase stability, extend oxidation life, and strengthen corrosion resistance under demanding turbine conditions.
Proven in over 40,000 hours of service, LSR™ coatings maintain their protective beta phase through repeated thermal cycles, helping parts withstand more service intervals without loss of strength or efficiency
The LSR™ coating process—available exclusively through Liburdi’s gas turbine repair services—produces aluminide coatings with precisely engineered microstructures that resist oxidation, corrosion, and thermal fatigue. By optimizing diffusion parameters and incorporating alloying elements such as silicon and chromium, LSR™ creates a stable, high-performance aluminide layer that shields turbine components operating in extreme temperature environments.
The result is a coating that enhances durability, reduces maintenance requirements, and supports consistent engine efficiency over multiple service intervals.
The LSR™ coating process offers exceptional flexibility for both internal and external turbine part protection. By incorporating alloying elements such as platinum, chromium, and palladium, coatings can be precisely tailored to meet specific oxidation and corrosion challenges. Whether applying multi-zone coatings or masking intricate geometries, LSR™ aluminide coatings deliver durable, high-performance protection while minimizing environmental impact through water-based binders and low-waste processing.
Yes. Air Plasma Spray (APS) coatings must be fully removed before any heat treatment or life-extension repair can take place. Stripping the APS coating ensures the base alloy can properly tolerate diffusion temperatures and allows for optimal bonding of the new LSR™ aluminide 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™ coatings are ideal for gas turbine hot-section components manufactured from nickel-, cobalt-, or iron-based alloys. Both internal and external surfaces can be coated, provided they meet furnace size and diffusion heat treatment requirements.
Field data confirms that LSR™ aluminide coatings maintain protective beta-phase aluminum for more than 40,000 hours of turbine operation, resisting oxidation, corrosion, and thermal cycling in demanding environments.
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.

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.
