You didnt really think you would get through this with no problems now did you? Well........? :) Try not to think of them as problems. Its a lot eisyer to deal with if you think of them as learning experiences!!
Little black spots or rings
showing through the plating after I pull it from the
tank Usually this is because all
of the bad corrosion was not initially cleaned out of the
pits. The chemicals reacted with the corrosion. Just drill
out that area again and put some more nickel on it by brush
plating. Dont put it in the nickel activator acid the part
will dissolve Plating is
peeling Couple of reasons
here....Usually it comes down to poor surface prep. Not all
the buffing compound was removed or contaminates in the
rinse water. Another reason could be too high of amperage.
Basically you baked the plating off. Either way you will
have to take all the old plating off and start
over. Part turned black or gray in the
mild acid etch.Or in the next plating
procedure. Been there, done that!! If
your part does this clean all the dark smut off and clean it
good! Dont put it in the acid etch again. It is some alloy
that will not stand the acid. I will sand a part like this
with 600 grit wet or dry to make sure fresh metal is exposed
for the initial nickel plate. Then plate right away.I have
had to go as far as zincating before plating some potmetal
to protect it in the nickel strike bath. Small pits in the finish after
plating. Couple of things could cause
this. First it is usually not a good agitation of the bath
during plating. Get the air bubbler going or turn it down
some if you have it running too much. Make sure your air
bubbler is putting out BIG bubbles. Small ones add to the
problem. Second your bath could have dirt or organic matter
in it. If this is the case run it through some coffee
filters in a home made holder. Part wound up across the room in
a violent manner against the wall. Dog is also running the
opposite way and wife is asking if your OK? Yup Ive been there too!!
TAKE A BREAK!!!! Re-think the whole procedure out.
