What is the Process of Plating Platinum and
Titanium Dioxide to Stainless Steel SUS 304/316L
June 13, 2008
I have already checked out the basics
Electroplating -- How It
Works
I need to get some SS tubes coated with Platinum and some with
Titanium Dioxide, How do I do that?
I will need these in an experiment involving production of Hydrogen
by Electrolysis / Sun light etc. And I am stuck in the middle of a
country were they do not understand what I am talking about. (Read
Norwegian in Thailand!)
I know I am talking about some of the toughest materials but ... You
never know. Maybe someone have a wonder cure for me!

Why tubes??
Platnitized titanium anodes used in metal recovery from waste
solutions are normally en expanded titanium. There are a few
companies that also make a multiple oxide coating on titanium (I will
guess that it is some kind of thermal spray process) and then the
really good ones are plated with Irridium)
Some anodes are plated with platinum and some are "clad". I have no
idea which is better.
Now to get water to electrolyze, it has to be very conductive, so
what are you going to use? Salt will have chlorine come off with the
oxygen and that might not be good.
Until you get your system perfected, I would buy commercial anodes or
have your anodes commercially plated. Platinum costs too much to set
up a line for a few parts and there is a steep learning curve for
high quality parts.
