An arrangement comprising a component (203) adjacent to a ceramic matrix composite in a gas turbine engine is shown. The component comprises a nickel-base superalloy substrate (301) and a cobalt-modified beta-nickel-aluminide coating (302) on the substrate to prevent interdiffusion between the substrate and the ceramic matrix composite. The substrate is coated by depositing a cobalt layer on the substrate, depositing an aluminium layer on the cobalt layer and then forming a cobalt-modified beta nickel aluminide coating.

A nickel-chromium (NiCr) alloy and a method for electrodepositing the NiCr 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 NiCr alloy including from 2 to 50 wt % chromium balanced with nickel. The turbine component coated with the NiCr 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.
