Nickel Black plating using pH 8-9 Nickel plating bath
February 10, 2013
Q. Hi guys,
I am a graduate student from MSU, and I have some questions related to Nickel plating on Stainless Steel 304 mesh.
I am trying to plating nickel onto stainless steel mesh using a basic nickel chloride bath described in scientific literature:
NiCl2 6H2O: 213g/l
Current density: 60 mA cm-2
This bath is employed to plate layers of nickel onto stainless steel and co-trap a suspended metallic powder (Ni-Al Alloy). I had some success in the past but noticed the bath only works sometimes, or after prolong electrolysis/plating. When I say success, I mean nickel black "powdery" looking surface with the Ni-Al powder trapped in the matrix of the plated nickel. During the failure times, I get a dull silvery looking surface, and the suspended powders are not trapped. Can anyone explain the situation and possibly offer me some suggestions? Thanks a tonne!
Have a pleasant day :D
