Titanium plating (Electrodeposition OF titanium)


A discussion started in 1999 & continuing through 2017 . . .

(2002)

Q. Dear sir,

Is titanium plating the same with term 'Cladding'? How can I apply Titanium plating to plastic mould or steel to strengthen its hardness. Do you know where can I learn or practice such thing because I work in the manufacturing company that makes spare-parts like gear, mould, cutting blade, etc.

Thank you Best regards,

A. Titanium is a very active metal which cannot be electroplated (out of a conventional aqueous bath). Cladding is a physical process where a skin of titanium is mechanically bonded to the substrate. But you are most likely talking about a vacuum deposited layer of titanium nitride.

A. By titanium coating do you mean titanium nitride? If so, it is not the same as cladding. Titanium nitride (TiN) is deposited by either chemical or physical vapor deposition. Cladding is more of a mechanical bonding process, and involves much, much thicker coatings. TiN and similar coatings are used extensively on cutting tools and wear components because the coatings are very hard (>2000 Hv) and very wear resistant. They are also used as decorative coatings on such items as faucets and door hardware because a wide range of colors, all the way from satin nickel to bronze, can be produced without changing the set-up (only the relative amount of process gases needs to be changed). Because the coatings are very thin, it is easy to maintain tolerances.

Physical vapor deposition

A. 'Body jewellery
Physical vapor deposition is often used to produce black implant-grade, autoclavable body jewellery. Biocompatible titanium coating is vaporized in an arc then electrically deposited on stainless steel jewellery.'

RFQ: I need to do 25,000 S.S. material rod to Titanium Plating which is .154 " diameter & 6 " long so please give me price. Thanks

A. Your inquiry is a bit vague, Mr. Shah, considering the comments that it is a follow-up to. You understood that you cannot electroplate titanium onto these rods? So, are you looking for mechanical cladding, or for vacuum deposition (and, if so, pure titanium or titanium nitride)? Is there a spec to comply to that would give people an idea of the thickness and the proposed purpose of the coating? Thanks!

Q. I have asked this question before but received unclear responses due to the confusing question I posed. I would like to know if Titanium can be electroless or electroplated onto steel and cast iron? Thank you very much for your time. Mark

Mark Robidoux

(1999)

A. No. Titanium cannot be electroless or electroplated onto steel and cast iron. Titanium is too active to electroplate. However, some alloys containing a small amount of titanium might be electroplatable; I'm not sure. Regards,

thumbs up signYou never cease to amaze me with your reference material, Mr. Budija! So I really am curious -- but these formula don't seem to offer any exotic solution to the problem of plating so active a metal, and I have to wonder about their validity. I hope someone tries them and gets back to us, but there has been erroneous stuff published in plating textbooks from time to time and my guess is this is one example :-(

Ed. note: To minimize duplication, offer more comprehensive information in one place, and ease the hunt for information, we've merged together several threads about the electrodeposition of titanium which were previously separate.

If it seems like the readers are 'ignoring' other responses in the thread, it's probably because at the time of their posting the other responses were in a separate thread and they didn't see them.

Q. I need to Titanium plate onto stainless steel. Having never attempted this I need some suggestions.

(2003)

A. Hi, D. You can't electroplate (in the conventional sense) titanium. The hydrogen in the water of solution will be reduced long before the titanium will be reduced.

It is not impossible to deposit titanium or any alloy of titanium in some fashion; in fact, titanium sputtered stainless steel sheet is commercially available -- but please explain what you are trying to do because conventional electroplating is impossible. Maybe it's titanium nitride vapor deposition (gold colored finish) that you are looking for?

? Michael, by what method are you "plating" SS. Clad-ok, PVD-OK. Electroplated?: I am with Ted, basically impossible, at least commercially.

A. Electroplating or electroless plating - no chance. However, try vacuum deposition technologies.

thumbs up signGentlemen:

Reading the full list of responses reminds me that the proper answer might reasonably be, "We cannot do it TODAY, but tomorrow the technology may allow it to be done." I would have agreed with all those who said it cannot be done, until one person steps up and says that it can. I am definitely going to file those ideas permanently.

Thank you,

A. Sorry for being a little late on this response folks. However, some useful discoveries were made in the mean time, so you could thank me for that!

The original question regarding Ti was not about Ti at all (when I checked into it last time, couple of months ago.) Some people think (or call) titanium nitride or other decorative compounds of Ti as Ti. The person was looking for gold and other color coatings. So when someone asks for Ti plating next time, let's have our question ready, what color is it?

Q. I still am curious about Mr. Budija's recipes, and can only add that the older I get the more I learn there's always more that I ignore. Just one question to him and all the chemists out there reading this, since the chemicals he mentioned are really not exactly my field: About formula 2, can an alkaline salt Ti(OH)2 be added to an acid solution of chlorides with a pH of 4-5 without precipitating its metal? Will the alkali be partially neutralized and water and titanium chloride form?

Thanks,

Q. I was doing a preliminary search on the feasibility of electroplating titanium onto Nickel and came across this message board.

Has anyone attempted the recipes proposed by Goran Budija, or confirmed the validity of the referenced material?

Its been about a year since the post above, so if anyone has had success during that time it would be great to hear about it. Thanks.

Hi Ryan. Personally I don't think Goran's formulas have any chance of working, but no one so far has tried them and told us the results.

(2005) -- this entry appended to this thread by editor in lieu of spawning a duplicative thread

Q. Dear sirs, I am very confused about titanium plating on bronze or aluminum products, and it is a very big fence,so we have to plate titanium separately, but we will have to weld them together, how to plate titanium on the surface where we weld, or is there any way to cover that part just like titanium plating? I'd be great appreciate if I can get your answer

Della Li
casting company - Shanghai, China


(2005)

A. Sorry Della, you cannot plate titanium out of a water based bath. It can be done with some very special equipment from an organic based bath, but it is expensive and limited to much smaller parts than a fence. You can basically forget welding any plated part. weld and then plate. Touch ups like brush plate on weld over plate are ugly!
Virtually anything other than galvanize or plastisol or vinyl coating or paint/powdercoat are going to be very expensive [for a fence], even in China.

I was involved a few years ago with a Canadian group that was working on a wet chemical plating system that could deposit titanium (as well as aluminum), but I'm pretty sure they're a long way away from production work. Titanium can be vacuum deposited, so Della may be calling that a plating, as the term ion plating is often used for vacuum deposition processes. However, your answer holds even more so for ion plating -- no way to touch up the weld areas, and even if you could you'd still have to put the entire object in the vacuum system. If you're going to do that, assuming that such a vacuum chamber exists, you might as well coat after welding.

Jim T.-- You are correct. I got sidetracked into thinking of aluminum plating. The correct reply should have been that there are no commercial methods of plating titanium on any metal.

Q. I am new to this site and I have a question about Titanium plating as well. Can smaller objects, specifically rings be plated and if so how durable are they? How would one go about plating with Ti?

Q. I am a student of Ph.D. (Chemistry)In Quaid-i-azam University Islamabad. I want to electroplate titanium on stainless steel. I do not know how it is done. I want to ask the procedure and possibilities of the reaction.

Java Intruder

A. Most of us think that it cannot be done, but if you read earlier letters in this thread, you will find possible recipes. If you try it, let us know if it worked for you.

James Watts

(2004)

A. About titanium plating, I know that some peoples are actually working on a titanium plating process in organic media, at room temperature. Will it work properly ? Do coatings made with this process offer performance enough for industries requirements? I don't know. However, as far as I know, preliminary tests were promising.

Moreover, as with Ted, that Titanium plating bath recipe presented on that discussion list left me speechless. This is the first time that I'm seeing a titanium plating bath made with water. My curiosity have been tickled and I will surely try it.

A. Aluminum is electroplated commercially. Siemens patented this back in 1978. The formula they present in the patent uses toluene as one of the constituents. It seems to me that the issues with electroplating aluminum and titanium are similar - so why shouldn't the solutions be similar?

David Ruben
- Tempe, Arizona


(2004)

thumbs up signThanks David. I'm familiar with the fact that aluminum is being plated commercially. Although aluminum and titanium share the similarity of being more electronegative than hydrogen, 'similar' is context sensitive, and apparently they're not similar enough to be plated out of the same or 'similar' plating baths, although as Daniel says, they're working on it.
