Electrochemical Metallizing - An Aircraft Turbine Engine Restoration Tool

Electrochemical Metallizing, a process whereby metal is selectively applied to rebuild and restore worn damaged, mismachined and corroded components, has long enjoyed use as an aircraft engine manufacturing tool. Repair coatings to corroded areas also have a long history of success. More recently, this high-speed coating process has been utilized as a turbine engine repair tool in F.A.A. approved overhaul and repair shops. Meeting both military and commercial aircraft specifications, electrochemical metallizing can be added to compliment an F.A.A. repair station's rework methods, increasing overhaul capabilities.

Worn stators, shaft diameters and endbell housings are easily rebuilt with electrochemical metallizing. Damaged gearbox faces can be restored. Many rotational engine components have been successfully refurbished. The paper will explore the use of electrochemical metallizing to repair these engine components. The use of semi-automated electrochemical metallizing for “production” pre-braze coating on stators during overhaul will also be detailed.
