Repairing process of a variable angle vane system in a turbo machine

摘要

The repair of a friction surface (46) of a turbine blade (14) consists of filling the deficit of worn material by the electrolytic deposition of metal, then forming, on this metal and the surrounding surface, a thin layer (64) of hard material with a low friction coefficient. An independent claim is also included for blades with variable adjustment for a recovery stage of a turbine, in particular an aircraft turbojet engine.
