Cast Iron-Plating-Stain in machined
part
+
Hi,
We are doing Zinc Plating on Iron Casting.(Potasium Chloride
Bath).The component is machined after plating. After 4 to 5 hrs of
machining stain marks develop from the plating edges and moves inside
the machined area.We had been plating the same component for the past
1 year without this problem.
Trials conducted:
- 1)Fresh plating soln prepared
- 2)Plating solution of another company tried out
- 3)Electrolytic cleaning included.
Any suggestions would highly be appreciated.
Thanks,
Rajesh Kumar
