Plating peeling on phosphor bronze springs

January 7, 2009

I am applying nickel via rack plating in a watts nickel bath to phosphor bronze springs. When the part is bent the plating peels off. I'm guessing it's an activation problem. Does anyone know of a good activation procedure for phosphor bronze?
