Sales of expensive x-ray instruments is not going well in this economy
so I am starting a new business, Mobile Marine Plating, Inc. *will
specialize in re-plating small marine parts with anti-corrosive and

plating". *This means we will go to a boat and coat corroded parts
with electroplated nickel or bronze or even gold. *Larger numbers of
parts can be brought back to the lab for polishing en masse and re-
coating.
My specialty is nickel plating but one of the most interesting ones is
an electroless nickel coating that has hexagonal boron nitride *in *it
to give ti lubricating properties along with the anti-corrosion
properties. *Think about steel or Aluminum parts that are subject to
wear and corrosion where a coating about .00020" thick would be
helpful.
I am getting tired of hanging out with scientists anyway and want to
hang out in marinas. *Will probably start off coating local parts but
will branch out into offshore oil stuff.

That's cool. *Best of luck to you in your new venture.

I try not to use a wire brush because that introduces metal from the
brush into the part. Pitting can be "fixed" by brush plating into the
pit and then finely lapping it to the surface contour.
I would expect to see many fixtures from older boats that need re-
coating. I would expect to see places where SS fasteners contact
aluminum because no matter how much of the stuff you put on the
fastener to prevent it, the junction always corrodes.
Fishing reels would be good to do here at the lab.
On-site means the part may not have to be removed from an engine or
other location to be plated. Brush plating is literally plating with
a tiny paint brush like thing so you can plate tiny areas. You dip
the brush into the plating solution and then rub it against the metal
part where you want the plating done.
Larger areas can be done by forming a dam around the area with silicon
putty.
