Thermal Spray Coatings for Power Generation in India

turbine rotor coating

We help to solve challenges in maintaining the surface integrity of components in continually operating power plants.

With expansion of economies resulting in the ever increasing demand for power, engineers and maintenance crews face the constant challenge to keep the power generation equipment in top gear despite continual wear issues that they face.

Ensuring benefits of lower downtime, higher reliability of components and longer service life.

Our HVOF/HVAF coatings work to enhance the endurance and wear resistance of critical equipment in the power generation industry and deliver multiple benefits. They are the ideal way to ensure long life serviceability of your components despite continual use.

The Shield of Endurance Impact

Hvaf coating offer excellent wear resistance, fracture toughtness, impact resistance and thermal shock resistance. Low stresses coating and porosity levels lead to increased service life of the component functionality

  • Our Enduro-511 is an excellent electrolytic chrome replacement coating which ensures 10 times the life with added wear resistance.
  • Enduro-411 coating for highest impact resistance,abrasion resistance and fracture toughness.

Typical Applications of HVOF and HVAF Coatings in India

  • Boiler Tubes
  • Turbine Blades
  • Guide Vanes
  • Valve Cones
  • Draught fan blades
  • pump sleeves
  • Pump shafts
  • Super heater tubes
  • Diffusers
  • Valve Seats
  • Cyclones
  • Valve Spindles
  • Nozzle Segments
  • Combustion Liners

Did you know?

The high ductility of our rotor coating reduces the risk of cracking if flexed and provides loading stress resistance, while the gas-tight structure provides corrosion resistance.

Pitting, corrosion fatigue and stress corrosion cracking problems all occur in steam turbines. The primary corrodents are sodium hydroxide, chloride, sulfates and sulfides.

Rotor pitting corrosion is commonly associated with chloride deposits.

The geothermal corrosive environment determines the choice of highly corrosion-resistant materials for rotors and blades. Different rotor and blade materials frequently result in electrochemical corrosion.
