Protecting Hydropower Turbines with IGS High Velocity Thermal Spray (HVTS)

Hydropower turbines are prone to corrosion, erosion, and cavitation, which result in metal wastage, reduced efficiency, and costly downtime. IGS provides cutting-edge High Velocity Thermal Spray (HVTS) solutions to protect essential hydropower assets, including:

• Kaplan turbines
• Francis turbines
• Pelton turbines
• Guiding vanes
• Penstocks

The Science Behind IGS HVTS

The proprietary HVTS process utilizes advanced thermal spray technologies. By carefully controlling the spray parameters and using specially formulated cladding materials, we can achieve optimal cladding properties for hydropower applications.

IGS Works Turnkey to:

• Prepare the substrate surface to ensure proper adhesion
• Heat the high nobility cladding material to a molten state
• Accelerate the molten particles towards the substrate at supersonic velocities
• Impact the particles onto the substrate to form a dense, adherent coating

The resulting cladding upgrades the metallurgy of the turbines and components, providing superior protection against corrosion, erosion, and cavitation. IGS HVTS does not require weld heat treatment or cure time.

Optimization of Hydropower Plants – Engineered for Performance

IGS HVTS solutions are engineered to deliver maximum performance and reliability in the demanding hydropower environment. Our claddings offer:

• High wear resistance to withstand erosion and cavitation
• Excellent corrosion resistance to protect against aggressive water chemistries
• Strong adhesion to the substrate to prevent delamination and spalling
• Low porosity and high density for improved cladding integrity
• Smooth surface finish to maintain optimal hydraulic profiles

With IGS HVTS, you can extend the life of your hydropower assets, improve efficiency, and reduce maintenance costs.
