This Can Coat Anything in TITANIUM

Titanium is a pretty fantastic materiel on it's own, but if you can coat things in it you can radically alter their properties. Or just make them super colorful. In several previous videos we've explored how to coat all sorts of things in a variety of metals and materials, but titanium was one of the few that refused to work no matter what we tried. In this video we've finally cracked it and using thermal evaporation manage to coat all sorts of things in titanium metal.

I used to work on ultra-high vacuum systems in the range of 10^-12 Torr. The thermal evaporation process is just simply that the heated material is overcoming the vapor pressure in the vacuum. This works with damn near anything you can put in the chamber. For best results, you want to get the vacuum as high as you possibly can. Looks like you're intent on switching to a stainless steel vacuum chamber which is the first step, the next step is that you need to use as much refractory material inside the chamber as possible so no organic materials or aluminum! Problem with organics is that they off-gas and aluminum is porous so it soaks up junk in atmosphere that it will off-gas for all eternity inside ultra-high vacuum environments, both effectively poisoning your vacuum. Also, you'r going to want to keep everything completely spotless clean, like clean room clean. A fingerprint on the inside of the chamber will poison the vacuum. Now for your pump setup, if you can get your hands on one, a turbo-molecular pump paired with a roughing up will get you to -9 Torr if you have proper material and good procedure, just don't turn the turbo pump on in regular atmosphere or you will grenade it.

Is you glass slide made out of SiO2? If so, could the O2 be reacting with the titanium to form TiO ? Hence the oxidation contamination could be from the glass itself?

@Michael Nilson i'm pretty sure there was the experiment with microwave plasma where he was using Borosilicate glass that had sodium ions in it. which messed up results too. stuff like t his is always interesting.

[@uwezimmermann5427]

the nice adhesive properties of titanium films onto both glass and pure silicon are because of surface reactions. It is absolutely plausible that a too thin titanium coating on glass fully oxidizes quickly, both from the glass and from the atmospheric side. A different material often used for sputtering metallic layers on microchips is an alloy of tungsten and titanium.

[@T3sl4]

Not quite, but actually maybe very much on the right track. Glass likes to have chemically bound water -- Si-OH groups on the surface. That might screw up bonding. Heating I think is the solution?

[@TheIdeanator]

Interesting question. The Ti might have enough energy to reduce the surface of the glass. I doubt it will have the energy to bury itself all that deeply in the glass and once that interface is created the Ti wouldn't really be able to react further.

[@abhimaanmayadam5713]

@Michael Nilson it was sodium in the glass causing issues. He used plastic instead.

As a Vape Enthusiast, I know a bit about Ti heating coils; you should be using DC Voltage, with 5 V max. I'd consider making a "Clapton" type coil wire for this apparatus (multiple parallel internal cores - like a freeway, and then fuse them together with an outer wrapped "sheath").

[@rotgertesla]

When i was doing that at university, we suspended the material to be coated at the top of the vacuum chamber. We also used the "boat" design to heat our coating material. Lastly, we used a laser to measure the thickness of the coating (with interferometry) in real time. The chamber was about 1 feet high if I recall correctly.

[@Spirit532]

I highly recommend avoiding vacuum grease at all costs. It's hell, gets everywhere, and kills your vacuum. It's outright banned in most labs for this very reason. The only two proper ways to do vacuum feedthroughs are to either have glass-to-metal seals(out of reach for you to make, and probably over budget for something DIY), or, the cheap and easy way - to use existing viton o-rings for KF flanges, and to make a flange seal outside the vacuum chamber, with two flat surfaces squeezing the o-ring, while the thread(with slits cut in it!!!) only provides mechanical pinching force. Both real and virtual leaks will haunt you if you don't do it this way. This also applies to the metal chamber you're building. Either just buying proper feedthroughs($$$) or building your own out of blank flange caps.

[@YodaWhat]

The endcaps of 'neon sign' tubing (low melting point leaded glass) are cheap and provide a way to get _wire through glass into vacuum_ that do not leak. Also, those electrodes are hollow and have getter inside them, which can be activated with a high-voltage discharge through imperfect vacuum. So use some just for that, and for general feedthroughs, cut them short on the hollow electrode side and take out the hollow electrode.

[@Spirit532]

​@@YodaWhat Almost correct, but they use borosilicate. Lead and soda glasses require gentle post-treatment with annealing, otherwise they're guaranteed to crack. However, there's no cheap off-the-shelf way to seal tubes of that diameter to chambers.

[@YodaWhat]

@@Spirit532 Having worked with a maker of Neon Signs, and closely observed his use of Propane and Oxygen-enriched Air to heat his glass, plus his evident lead poisoning, I will stick with my original statement. Working borosilicate glass requires much higher temperatures than his setup, typically Oxy-Acetylene flames. Then, the glass is annealed at the same time the electrode getter is activated, by passing much more than usual power through the tubes.

[@Spirit532]

​@@YodaWhat Borosilicate does not require an oxyacetylene flame. You can soften it enough to work it with an air-propane flame, or work with it properly with either oxypropane, or what I'm using to make glass to metal seals, air+MAPP(though I will switch to oxypropane, some of my operations are uncomfortable without the option to get a sooty carbon flame). I've also used air-propane to make borosilicate pipettes in the past. As for annealing - I have no experience with neon sign manufacturing, but I'm assuming that blasting the tube with a few hundred watts is just about enough to get it around the annealing point, but the stems come pre-annealed anyway, you're only annealing the joints and bends.

[@YodaWhat]

@@Spirit532 Ok, if you say so, but the makers of scientific glassware I have seen at work were using OxyAcetylene, which is more expensive and much hotter than any other common torch mixture. Anyway, here is a chart of various relevant temperatures for several types of glass: slideplayer.com/slide/4235773/14/images/18/Important+in+glass+forming+operations+are+the+viscosity-temperature+characteristics+of+glass..jpg

Hey dude, I love your videos. There is another way you can improve your build, instead of using titanium or aluminium wire, you can coil up tungsten wire, and run high current in it, it can easy get to very high temperatures, if you insert aluminium or titanium wire inside the coil it will vaporise the metal and coat everything you have inside the chamber. I've been using this method to coat surface mirrors, with a hacked MOT, and, Grant's scariac. Hope this info will help in a future build.

[@maxk4324]

First off, phenomenal video and congrats on yet another DIY conquest! Second, I can't decide if I'm more excited or furious that titanium sputter coating is as simple as "add heat" (minus the vacuuming steps ofcourse). Now, I may be but a lowly student of mechanical engineering, but as fellow vacuum/plasma/high voltage enthusiast I have some ideas that might improve the process. No idea if these will actually work, their just my best guesses after watching your video, but here goes. 1) Assuming that a straight titanium wire sputters titanium atoms in a similar pattern to how a fluorescent tube lamp in a tanning booth emits photons, if you arranged a bunch of these straight wires in an arc above the target such that they are parallel to the arc's axis of rotation (same configuration as the lamps in a tanning booth) it should concentrate more sputtered titanium on the target than a simple flat array of straight wires would. As well, by increasing the central angle of the arc it could help get titanium around tricky corners of the target. Or you could make it a full rap around cylinder of straight wires like a sort of cage to do a full 360 coat, but this might be a hassle to set up. 2) It might streamline things if you made the titanium wire preformed titanium wire elements. So taking my suggestion of the titanium tanning booth as an example, if you had the ends of the straight wire sections come together to form two bulkier wires (one per end) and then curled those bulkier wires in loops slightly larger than the bolts you used, so long as you are gentle with it all you have to do is put the target in position, take the top nut off of each bolt, drop in the preformed wire arrangement, replace the nuts, and then bam you're ready to start the process. This way, once you find the best wire arrangement for a given process you can just stockpile a bunch of copies of that array and swap in a new one as soon as you need it. 3) As you mentioned, this process is commonly used as a secondary vacuum pump, so maybe if you have a big enough chamber you could install a second heated titanium wire on separate set of bolts to act as a secondary vacuum pump. You could put it off in a corner somewhere so that it won't have much impact on the coating process and connect it to a separate circuit so that you can run it for a while before heating up the coating wire in order to improve the vacuum. My guess (and it's 100% a guess) is that while the geometry of the coating wire has the most effect on coat uniformity for a given target, the deeper vacuum may improve the repeatability of the results by further removing stray gas atoms from randomly intercepting the titanium atoms being sputtered from the coating wire. Anyway, on the off chance that you do read this and that you had the patience to read through my likely bogus suggestions, thanks for all the help your videos have given in the fields of vacuum systems, plasmas, and high voltage circuitry. And as always, I'm looking forward to your next video, whatever it's about!

[@YodaWhat]

You have good suggestions there, but to coat evenly from all sides, it is perhaps simpler just to make a loop large enough to surround the target. Study of the ways filaments are supported in incandescent light bulbs can be instructive. Also, (and especially if desiring the beautiful golden hues of Titanium Nitride) use Nitrogen purge gas instead of Argon. It will also make a much better vacuum via _sputter pumping_ than Argon, because Argon will not combine chemically. Argon is an _inert gas._

I remember seeing the original video on this sputtering setup but this one apparently slipped by me. Super interesting about the carbon coatings. Not sure where you got to with the "diamond" testing but deposited carbon, depending on the process, will have some fractional combination of sp^3 (diamond) and sp^2 (graphite) bonds. A good method to test is using Raman spectroscopy to get the percentage of each. If you wanted to get a rough idea of whether the deposited film is more graphitic or diamond-like you could measure the resistivity, since one will be high and the other will be low.
