ELECTRODEPOSITED NICKEL-CHROMIUM ALLOY

Abstract:

A nickel-chromium (Ni--Cr) alloy and a method for electrodepositing the Ni--Cr alloy on a turbine engine component for dimensionally restoring the engine component are described. The engine component is restored by rebuilding wall thickness with the Ni--Cr alloy including from 2 to 50 wt % chromium balanced with nickel. The turbine component coated with the Ni--Cr alloy is heat-treated at a high temperature to homogenize composition of the alloy to mimic the base alloy and to restore materials lost during repair of the turbine component.
