I've been anodizing titanium for years. The grade of ti affects the colour as well as the surface polish. Fun stuff! 👍
Cool
Are there big differences anodizing Gr2 vs Gr5 titanium?
@@mitchel90mcnee Yep. Grade 4 seems to work best.
@@jamesbarisitz4794 Thank you for the info, now I know what to do at work today!🥸
Does it come off easily?
I never considered that it was weird how snow is a different colour to ice.
😂 He glanced over that like I knew that
Or translucent soap and white bubbles.
I mean, ice is solid. Snow is not. It's not surprising that they reflect light differently
@@contraband1543 Snow is a solid... So is sawdust.
@@ShAd0wE1337 And now tell me sawdust has a grain structure. ;) At least none of both (the lignin etc. stuff) is translucent. But HIPS if injection molded is translucent, and at the same time expanded styropor is white. As long there is no colouring additive, but just virgin plastic is used. Well some different additives are also in both forms I think.
Ah thin film interference. One of my favorite things. I've actually plotted out the colors you should get in Kaleidagraph, based on the wave theory. For normal triphosphor fluorescent light, you get a very distinctive color pattern that can be seen at 3:53. This order of colors is specific to the light source and would look different if you used an LED light or an incandescent light instead. The first few colors tend to stay the same though, as long as it's normal white light.
Cool
Cool
Cool
Honestly, cool
Cool
I used to Tig weld stainless steel, you can get great colours.

Hey, I want to turn some stainless steel screws goldish-yellow, do you know how I can do that somewhat easy and reproducable?
@@Donnerwamp nickel plating, plenty of DIY videos in it
I really do love titanium and how "unique" it is (from the process used to make it, how "strong" it is, how it's more complex to form, how heat resistant it is etc.). To me it's the most fascinating thing in metallurgy when you first discover it. Also Action Lab, I know that we all have a right to make money off our services and I understand that ad revenue is a good source of it, so I just wanted to say that I'm glad you openly disclosed your sponsor at the end of the video. It's my favourite way content creators advertise for other companies' products and I hope to see more of it presented this way.
100%, you get an A+.
Titanium is great for piercings, and being able to anodise it to make pretty colours means it’s more appealing to people too!
It’s also great for jewellery if you don’t want piercings :)
Very interesting, didn't realize this was caused by the wave properties of light! Good stuff, one of my favs from you.
COME ON 4 MILLION
When you look at metal shavings from a CNC mill, you can see that it takes on a very strong pinkish/purple color due to the strong heat generated when shaving the pieces off. My instructor at work used to collect the metal shavings from the lathes and mills down in the shop to explain heat treatments to us.
There is also titanium nitride as well forming in the air which of course is a beautiful gold color and is seen on drill bits.
You didn't mention it, but microcenter carries other fun things like 3D printers, drones, Raspberry Pi (and tons of accessories) simple robot kits, electronics and much more - they do have a lot of tech in the store. One of my favorite stores!
Yeah a cool store foe sure! A much better sponsor than sitting through some of the other sponsors he's had.
Oh nice!
I wear a titanium ring that has a groove around it with the blue colour at the bottom. The great thing is the stability of the colour. I like the ring because it reminds me of the grooves for the rings on a piston. Plus, when you drop it on someone's palm they are amazed at how light it is.
My friend brought a titanium bolt to school from some new ford back in 2015. Almost everyone bet it was aluminum. He made like 60 bucks that day lol He proved it was titanium with a file
@@contraband1543 Cool story, but I'm not filing my ring for anyone!
Awesome experiment! I'm always learning a ton from you and I appreciate it. Years ago I acquired some pure Niobium and a Ferro-Niobium alloy which I did many color change experiments on. As I remember there may be like 5 different oxides that can form which affects the color it appears. Also I think it could be achieved using chemical, heat, or electrical means...but it's been a long time.
I never wondered why soap bubbles have rainbow reflection, thank you for opening that bubble in my brain!
"It doesn't have to be Trisodium Phosphate...you can just use table salt"
Had the same energy as "it's just a balloon on a cup"
someone should start a company that sells titanium engravings fully in color without paint using these techniques (or smth similar)
I'm curious about the resistance of thing covering, like, if someone makes the handle of a knife or a tool using something like that.
Excellent explanation, thanks!
you ever see those channels where they take some tool that's been rusted for decades and make it new again? Thats so cool
The layering of the titanium dioxide is what causes the light to diffuse and cancellation of wavelengths. Nice!
You did not reference the many other elements that use refractive oxide microstructures and color changes ☺️. Thanks, keep making these videos.
Can you list them?
VIDEO IDEA: buy a telescope and then disassemble and paint the walls in vantablack then test if it’s better at absorbing light
How would anodized Titanium react if it was in a different light surrounding it, for instance UV, IR or any other form of Light that isn´t white light. Would it show different colors?
If its a monochromatic light then the titanium coin will look either dark or bright for destructive and constructive interferences respectively depending on the thickness of the oxide layer. If its UV or IR, the same thing will happen but we humans won't see it.
i wondered years ago if there's colours that we don't know or we can't see because we don't have those things that make us see specific colours like red green and blue, and how would we notice if the colours are there but just that we are blind to those colours like dogs are colourblind to some colours (I can't recall which)
i heard that a species of animal (i also can't recall which, maybe it's flies or maybe not) can see ultraviolet light (?) or some other frequencies
Gotta remember to check this link, that pre-built custom pc sounds like a great tool
I love this channel, and have tried some of your experiments in the past.
For fun I sometimes play your videos at a slower speed to sound like a weird acid trip. Try it :)
Changing playback speed to 0.25x maximizes the LSD effect, and I am in diaphragmatic pain with the resultant laughter 😃! It's so cool that DSP can time shift the audio while preventing pitch shift. First encountered this playing with a Korg digital audio effects processor; blew my mind 😳
@@stephanrosos4957 the descripted words used that makes it all work. I'm glad you found it funny because I thought it was just me. Thank you for the reply. 😉
This video inspired an art project for me
Just wanted to say thank you for still doing the longer form videos.
I don't understand the push for channels like this to make more sub-minute shorts. I can see how it might be better for more mundane subject, but explaining technical and scientific phenomena isn't terribly conducive to Short Attention Span theater in the first place.
Keep up the good work!
Excellent practical explanation 👏 👌 👍
Real people like practicals... 😊
How light works and different effects of it is the most interesting topic to me
Quite a while ago, I got rainbow utensils, they were mostly magenta, but some parts were yellow, or blue, and now I know why they are that color.
Interesting, I've always thought that the titanium dioxide layer was refracting light in some way, but it's actually wave interference. Nice! Maybe I'll get a chance to try this myself
Awesome. Super interesting. When/how does the color fade away?
Thanks, James, this was fun!
Also titanium dioxide insulates which is why you don't want to use it as an anode, it works great as a cathode though.
I don't know why, but the fact that the key phrase in this video is "Controlling the thickness" and the way he says it, just stirrs something in me
this was really fascinating
Try heating polished titanium and dipping it in ferric chloride. Entropic finish
Bismuth is another really cool metal. It's colors change depending of the oxidation state of the surface of the metal. Also liquid bismuth makes cool crystals when it hardens and crystalizes.
I actually work at an anodizing shop we anodize aluminum we use titanium to rack the aluminum parts on it and run it through
"rainbow metal" has been my favorite thing since I was a teen. I want to get an anodizer to make my own jewelry and accessories. There's not enough of this!! Personally I'm baffled that colorful metals aren't the NORM.
Different grades of carbon steel and other alloys can make some cool colors as well when anodized with different acidic or metal salt solutions… I used to have a blacksmithing business.
There's a ultra-luxury watch brand called DeBethune that does this to their dials. They are absolute masters of titanium anodization.
..Very very interesting!!!
..Thank you so much for explaining it to us... 👏🏼👌🏼👍🏼💙
Love you even more, seeing that VW bus on your shirt!!
These videos deserve way more views
When welding stainless steel it gets pretty vibrant to me.
Great! Now I just need confirmation that this method can be reliably used to turn copper green.
So far I managed to turn it blue by dipping it in vinegar+salt.
Why? Because aliens **insert crazy ancient aliens dude**
This was a cool one James.
I love Micro Center!!!
My bikes full titanium exhaust is very pretty, all kinds of colors. I love it.
Very interesting. Does the color depend on the angle of the incident light and/or the angle of viewing?
i think it does sometimes? oil slicks can have a dramatic shift in color depending on angle
You can ano Ti with 9 volt batteries and there are some crazy patterns you can make! Toxic anos are definitely the best imo
Glee! Titanium exhaust leggooooo
Thanks for that explanation for light refraction I am doing a level physics and didn't understand it til noy
Microcenter and shank mods just did something really cool with an old as heck hot wheels computer on CZcams
52100 steel gets pretty colorful too
Grade 2 (commercially pure) is the prettiest of the Ti options in my experience. Grade 5 is sexier as a material but responds less vibrantly.
Good work always by you
Very cool video!!
This looks like magic
Thin film interference would predict a rainbow pattern reflection, with all colors showing at some definite angle, but the oxide surface clearly shows just one color. Any simple explanation for the supression of the other colors?
Wondering that as well
I like cars and a lot of aftermarket exhausts have this coloration, mostly because the car spits flames. Paganis have this coloration on the exhaust tip.
What if you use different light sources that had different colors different combinations
If I never see another Zaxbys commercial it will be too soon.
i applied for the coupon only to realize its an instore only item and there arent any stores like that in WA
I wish there was a microcenter near me :c
*Snow looks white* ~ _Action_ _Lab_
meanwhile:
_snow_ _white_ : -white-
Reminds me of stained glass techniques kinda
love me some good anodization
quick question - if you do a electron microscope scan - is the Titanium Dioxide a ridge and valley orientation - much like butterfly wings?
Well done!
Could you do a video on whistling? It's always stumped me
Très intéressant ! Merci ! 👍🙂
TAL can take any topic and make it seem interesting ❤
Always asked me this thx for explaining love your videos.
Where do I get that power supply and what is it actually called?
Can you find a different solution to non stick your iron pan? The standard procedere is heating it amd burning it in with oil, but many people fail to create an even surface with the non stick carbonised oil.
Snow is clear... I had no idea, honestly lol
hi , can you leave me a link to your bench power supply , or shear brand deatils
Awesome! I was wondering how titanium jewelry can come in so many colors while not being painted
Can Glass also hav the same effect if thin enough just curious?
So Does that mean you can anodize a bubble in the same way?
Dude thank you you are awesome please show us more ways we can make money off of our power supplies
One question what were to happen if you put jello in a vacuum chamber
Is it possible to change the color of titanium dioxide itself. I know they use it to make paint pigments and also color shifting pearl pigments.
Does this work the same with stainless steel?
Another really good metal to anodize is niobium, you can get so many colors
Aw well as vanadium.
Is that reversible by reducing voltage.?
Wow amazing that it does that
"40 volts that's a pretty color"
I'm considering doing this to a titanium dive knife... would the oxide layer negatively effect the knife in any way e.g. salt water corrosion/hardness etc? I'm guessing that it shouldn't and any effect that it had would be surface only?
Shouldn't change it's corrosion resistance, at least on the inside. The oxides are pretty scratch resistant on titanium though, and the process can be repeated if the finish becomes too scuffed from use.
It shouldn't have much effect. The titanium oxide layer is very thin at few hundread nanometers. its very stable in salt water. I also don't think it will affect the cutting properties.
Haven't done this myself but I have a degree in materials science.
Have a look at De Béthune kind of blue watch :)
Why doesn't the oxide layer just gradualy keep growing under a certain voltage?
Hi @theactionlab.....can you try a piece of aerogel in a vacuum...
Very cool, even enjoyed the ad
Man, you're killing this channel by uploading the same thing on to your shorts channel. Great video but I dont feel like watching these videos because I know I will be able to watch a summarised version in a few days. I've been subbed since you had like 100k subs. I still remember your old logo. Hope you reach 4mil soon!
He does not summarize them in order.
Does it work with zinc?
Really cool
Keep growing sir
The mouth piece on my Trombone is made of titanium and it has turned purple on the inside after a while of use. Is it really getting that hot in there?
