Dealing with Reactive Metals has been a real pleasure - very helpful, great communications - quick delivery - so if your interested in doing Anodizing Niobium/titanium then contact them
check out the Annodizing Video - its great - Rio Grande posted but its by Bill Seeley - founder of Reactive Metals Studio : He makes it look so simple - !!!!
I ordered the Thesis on Annodizing Titanium - its only 5.60 with your order but its full of great information on what Titanium is, how Annodizing works etc....
so I think I am ready to do this on the weekend-- I will detail out as I set up myself but this is what you need
A reminder - I would be remise in not mentioning you could shock yourself - we are working with electricity - so wear the rubber gloves ! follow the instructions (which look simple)
I have my Annodizer unit (for at least 12 years )
you can get this as a full kit
which I did long ago from Reactive Metals or you can also get kit from Rio Grande
Your set up (and I hope mine ) will look something like this
the only thing about this pic is the person is NOT wearing the rubber gloves -
Plastic container- non conductive material - glass would work too - plastic mesh so you dont touch the stainless steal anode with your metal
Black clip is on the anode and red is on the conductive wire/sheet/tube (metal)
the water is distilled or bottled water without chemicals (they list other liquids you could use - there is a reason) - evidently chlorine does not help the reaction - and you add TSP to the water which helps the reaction as well
More explanation on the weekend as I set up step by step - I am so excited I am doing something other than paper cutting .......
