Repair of turbine blades:

Repair steps:

Blade registration number - blade weighing record - making blade blade template, blade sandblasting, removing thermal barrier coating - blade washing - removing bottom layer (MCrAlY layer) Select blade sampling for analysis to judge and analyze blade fatigue Lifetime - Observation of tissue status (fluorescence inspection of all blades, registration of faulty blades) - evaluation of repair risk:

a. Solution treatment before welding 

b. Troubleshooting

c. Welding 

d. Inspection/Fluorescence

e. Hot isostatic pressing 

f. X-ray/fluorescence

g. Heat treatment, accessory production, lock plate production, counterweight pins, positioning pins

Rebuild the coating system - check the air cooling holes and clean the air cooling holes - weigh and sort by weight

Packaging - Issuing Certificate of Conformity

Turbine blade failure forms: 

A, wounded, tip wear, corrosion. 

B, stress crack, crack in high temperature to change. 

C, wear-resisting layer damping surface wear or loss (secondary and tertiary blade)
