Two Special Cost-Effective Applications for Electrochemical Metallizing for Improved Brazing and Bonding

TWO SPECIALTY APPLICATIONS for electrochemical metallizing have recently proved cost-effective and technologically sound.

Aircraft engine manufacturers and maintenance facilities find nickel electrochemical metallizing an excellent way to enhance braze-ability of super alloys on turbine engines and other components. A base nickel deposit permits even brazing at lower temperatures, avoiding heat damage to adjacent honeycomb.

Aluminum helicopter rotors present bonding problems, now solved by selective electrochemical anodizing. Leading edges are often covered with a hard alloy shield or a layer of synthetic rubber, bonded to the aluminum base with high-strength adhesives. Selective electrochemical anodizing leading edges of rotors guarantees adhesion vastly superior to direct bonding.
