METHOD FOR REPAIRING VANE OF JET APPARATUS OF TURBINE OF GAS-TURBINE ENGINE Russian patent published in 2002 - IPC

FIELD: machine engineering, namely turbine making, particularly restoration of damaged surfaces of flanges of vanes of jet apparatus of turbines. SUBSTANCE: method comprises steps of hydraulic shot blasting of restored surface after preliminary working of said surface for receiving rough dull surface; similarly working contact surface of joined plate member; securing nickel gauze to surface of joined member; fastening joined member at closely pressing it with formation of step to restored surface and applying solder into formed angle; placing vane in vacuum furnace in such a way that said step is turned upwards and heating it stepwise until achieving temperature of solder melting; after cooling vane subjecting it to working according to design dimensions. EFFECT: enhanced quality of restored surfaces, namely their high strength. 2 cl, 1 dwg
