Rejuvenation and Repair of Turbine Blades, BLADE CAREER, Hot Section


Certified ByTrust

Product Introduction:

When a gas turbine blade is working at a high temperature, various damages can occur to it. These damages may be physical or related to the microstructure; Therefore, with the passage of time, the part loses its initial efficiency. The repair of gas turbine parts takes place in different stages, during which the metallurgical and dimensional properties of the parts are restored. In general, the moving and fixed components of the gas turbine suffer from the following damages:

* External physical damage: External damage includes fatigue cracks, surface oxidation and corrosion, FOD and abrasion.

* Repair: often involves grinding, welding and smoothing and sometimes brazing.

* Internal microstructural damage: Internal microstructural damage also includes the dissolution of carbides at the grain boundary, change in the Γ ′ phase, change in grain size, and the structure of the nickel-based superalloy, which can be solved by rejuvenating heat treatment.

* Dimensional defects: Any dimensional defects that develop on the blades over time.
