The Effects of Variables in Nickel Brush Plating on Brazeability of Superalloys

Waspaloy sample panels are brush plated with sulfamate nickel (AeroNikl 250®) under various plating conditions. The wettability of these panels by molten brazing filler metal AMS 4777B is evaluated. Results of the observations are verified by metallographical examination. Conclusions are made about the effects of brush plating process variables on brazeability.
