Influence of the oxide scale features on the electrochemical descaling and stripping of aluminide coatings

Turbine components are subjected to very aggressive environments at high temperatures leading to corrosion and/or oxidation. Because of their high cost, they have to be repaired instead of being replaced. Prior to refurbishment and recoating, the components have to be fully stripped to remove the ox...
