Repair of Diffusion Coatings 700332

Repair of diffusion coatings applied to jet engine gas path parts is accomplished when the coatings show wear from foreign object damage, erosion, corrosion, and oxidation/sulfidation attack. Inspection of diffusion coatings is currently limited to conventional visual methods which are insufficient for determining the integrity of the coating and its accompanying diffusion zone. Successfully used diffusion coatings have been tailored to the parent material's heat treatment requirements so that the coated alloy has maximum resistance to corrosion, erosion, and oxidation/sulfidation with minimum effects on the fatigue and stress-rupture properties of the parent material.
