Titanium Plating
2004
I am trying to plate titanium. I'm trying to use the formulas that Goran Budija, from Zagreb, Croatia, had posted (letter 25024). They required titanium hydroxide, or titanium metatitanate. However these chemicals are not readily available. In fact I can't find them anywhere, and a company wants $1500 to make a kg of Ti(OH)4. One of Goran's recipes was to use 100 g of Ti (OH)4, with 40 g of HCl, and 100 g NH4Cl, with a liter of water, to a pH of 4 to 5.This seems like it would be the equivalent to neutralizing a TiCl3, HCl mixture with ammonium chloride.
I have read a report commissioned by Wright Air Development Center, WADC, on the "Electrodeposition of Titanium" to the Missouri School of Mines and Metallurgy, in 1954, and they had experimented with titanium hydroxides and titanium chlorides. So I think it can be done.
The other recipe was to use 70 g sodium metatitanate, 30 g sodium acetate, 30 g sodium hydroxide, and a liter of water. This recipe is completely new to me. What I need is a source or method of getting titanium into these recipes. Any ideas Goran?

Titanium can be easily deposited by physical vapor deposition (for coatings < 1 mil) or by low pressure plasma spray (for coatings > 1 mil).

Dear Marc!
Recipes are from one Ukrainian book
(L.I.Kadaner:Galvanostegia/Electroplating/Kiev 1964.) Other formulas from this book:
1.100 gm Ti(OH)2,250 gm HF(50 Be),50 gm NH4F,2 gm scotch glue,1 lit water,20-50 C,2-3 A/dm2(standard formula for Ti plating,very dangerous stuff)
2. 400 gm Ti(OH)2,1 lit H2SO4(11 Be),platinum anodes,10-15 A/dm2
3.38 gm TiCl3(or TiI3 ,or mixture of 20 gm TiF3 and 20 gm TiI3),200 ml toluene,800 ml ethyl alcohol,0,O2 pitch or resin(Ukrainian
=smola?!),18 C,21 A/dm2,graphite anodes All titanium compounds are expensive-except impure titanium oxide(Ti white)-good luck!

According to a Russian handbook , for Ti plating suggested almost the same formulas. For a base metal you should use a metal with high hydrogen over potential such as Pb, Zn, Al. As the book state's coating is compact. Hope this helps .

Many Russian plating handbooks with chapter on titanium plating(from water or solvent based solutions) can be downloaded(free) from next website http://lib.prometey.org/
Hope it helps and good luck!

I understand that titanium cannot be electroplated. Is there a way to put a .002 inch layer of Ti or TiN on copper ? I need to coat the end of a copper rod that is .090 inch diameter.
Thank you.
