Repair of steam turbine blades

The main types of steam turbine blade damages are:

  1. Attack by corrosion;
  2. Erosion;


The company has developed the new technology for steam turbine blade recovery with hardening of the leading edge without breaking airfoil profile of the blade itself.

Restorative repair includes:
1) Thermal treatment;
2) Renovation of airfoil profile;
3) Welding of armor coat (Stellite).

This technology was presented at the All-Russian competition for the support of high-tech innovative youth projects and has become one of the winners. The company received a patent on it.
