Hi,
I have to plate Co-P alloy from a bath consisting of Cobalt sulphate, cobalt
chloride and Sodium Hypophosphite. The pH of the solution is about 4. I plate at
room temperature and no agitation is required for my plating. The thickness I
would like to about is in the order of 500nm and might go upto 2 microns. The
current density ranges from 2.5mA/cm^2- 10mA/cm^2. The only problem with my
plating is non-uniformity. I have read several queries about non- uniformity in
this forum , some suggested to use levelers/ brighteners would these be the
solution to my problem. If so what kind of levelers should I use , will they
change the magnetic properties of my alloy? What will I have to do get a uniform
plating , I use a potentiostat for constat current. I would appreciate if any
one could help me in finding a solution to this problem.
Thanx and regards,

fabbi.
