What's amazing to think is the different colors come from the different layers of the electroplating material as the crystalin structure changes thru the layers build up resulting in the different colors
Das ist Anodisieren von Titan. Dabei ist die Schraube oder das Wekstück die Anode also der positive Pol. Die Farbe kommt daher zustande das die Schicht welche durch diesen Prozess ensteht das Lichtbricht und dann eine spezifische Farbe reflektiert wird.
Es oxidiert im Mikrometerbereich, kleiner als die Wellenlänge des Lichtes. Die Oxidschichtstärke bestimmt die reflektierte Wällenlänge durch Interferenzbildung.
Anodizing. It's cool right!? The more he puts electricity to it the thicker the coating becomes. The thickness of the coating determines the color. We're you anodizing titanium?
Anodizing is different from electroplating. Anodizing is in a sense replicating the metal to thicken its surface to protect it while plating is using another metal to coat the bolts for their protective surface.
The thicker coating has smaller gaps between the molecules. This determines the wavelength (therefore the colour) of the light which is reflected. The rest of the light is absorbed.
dumb description, its not electroplating. it's called anodization of titanium, and different voltages applied determine the color by changing the thickness of the oxide layer. this person is simply changing the voltage on the power supply and touching the bolts for a moment. only special requirement is a dc power supply that can vary output from about 12V to 105V to get the full spectrum of colors.
@@thatdude6045 no they are not. anodizing uses electricity passed through an electrolyte to cause an oxide layer to form on the surface of the material. most important distinction is that the oxide layer is formed from the base material itself. electroplating is the bonding of a separate material that is dissolved or otherwise chemically present in the electrolyte. almost any conductive material can be electroplated, but only a half-dozen metals that naturally form an oxide layer can be anodized. aluminum, magnesium, titanium etc.
Anodizing. An electrical charge travels through the water and to the metal mesh, which I'm assuming in this case is zinc. A transfer of ions begins between the two metals, and the zinc binds to the other metal like a coating around it. This is more preferred to paint because an electrochemical process occurs that literally binds the coating to the metal.
That's because the color is the result of the oxide layer thickness. The thicker the layer the longer the wavelengths it will absorb. So as the layer gets thicker, only the longer and longer wavelengths get reflected. This is why it starts out as blue and then gets progressively redder.
Those titanium screws are probably super expensive haha. We sold some titanium screws where I worked and they’re go for a couple hundred dollars a piece. They were slightly larger and for aircraft so I’m sure that plays a role in the price.
The color change is epic. But do you see what I see? The splitting of the liquid happens most when in contact with the bolts! This possibly means that more surface area is needed for a hho gen to work batter!
This coloring is the result of a phenomenon called thin film interference. The thickness of the oxide layer being formed is about the same size as the wavelength of visible light. When the layer is thinnest, around the wavelength of blue light, incoming blue light is able to fit one full wavelength with the nodes of the wave located at the interface between the oxide and the air and the interface between the oxide and the bolt at the same time. This reduces absorption and increases reflection. Meanwhile, longer wavelengths don't fit, so they get scattered or absorbed more, and so the bolt looks blue. As the thickness increases, blue light no longer fits within the oxide layer perfectly, but longer wavelengths do, so the screw becomes more yellow, green, orange, or red. The effect is more pronounced for different materials, and sometimes blue and yellow are the only ones that you end up seeing as the oxide layer becomes more uneven or the material interacts with longer wavelengths differently. Go look at bismuth for some really stunning examples! At the end of the video, you can see the return of some blue color as the thickness becomes double the wavelength of blue light, allowing exactly two wavelengths to fit in. This is also why soap bubbles and oil slicks on water can show all the colors of the rainbow, as the wall of the bubble or the layer of oil that form become very thin. Some insect wings, bird feathers, and reptile scales display similar effects, but not exactly the same as thin film interference. They usually make use of very small 3-dimensional structures with sizes comparable to visible light to achieve brilliant colors without the use of pigment. This is called structural color, and it results in some really fascinating and beautiful visual effects.
If you connect electricity with different voltages to titanium, you can see its amazing color change. Titanium is a metal that changes color if electricity reaches it with different currents, of course you need a water solution with baking soda.
So there’s like a 50% chance I know what’s actually going on. I’m guessing those are stainless steel bolts and if you’ve ever done a little bit of research about stainless steel it changes colors when it gets heated up so I’m pretty sure that’s right.
@tims_always_fishing7117 For now our Prime Dictator allows it, until he senses a great Canadian bolt uprising, at that point he will ban them and put on a celebratory brown face. 😂
@AscheOfTheLake 😂 I've personally never heard a single person call a garbage disposal that, but I wouldn't put it past back country Canadians... bunch of savages.... or maybe people from Quebec lol.
I thought you could just program the voltage in and it changes to that color, what is he using, there are charts that show the color change for voltage 9 - 90 volts
@Zoooker1 I think he's referring to the arcing from touching the screw with the cathode. That its damaging the threads (and it is look at the marring on one of them)
@@EyebrowsMahoney You’re absolutely right about that, he shouldn’t need to touch them directly (though I dont know the answer to whether it’s enough V to damage the threads)
Is this what cheap "NON-STICK" cookware gets? Looks like I can do it home on a cheap cast iron pan with great proportions and dimensions (better angles and surface area than the garbage at most stores...)
