My bright nickel plating bath is giving me a lot of grief. Our problem is the lack of uniform brightness on the part. The side of the part directly facing the anode is bright in some cases but not others. If I attempt to plate multiple parts in the plating bath I get different shades of brightness on each of the parts. I performed a carbon treatment on the bath with no improvement in the results. Do you have any suggestions for how to resolve this problem?

We are plating electroless nickel (EN) on leaded brass, but find pits in the EN layer. What is the best way to prepare the leaded brass substrate so that we do not get a pitted finish?
We have a decorative chrome plating process using hex-chrome and find that, in the high current density areas, there is cloudiness more often than not. What should we be looking for to solve this problem?
Q. Our company produces components made from mild steel that are nickel/zinc plated. We have been asked to investigate the possibility of over-plating of a tin strip on these parts. Can this be done, and can it be done selectively?
