STRANGE MARGINAL GAINS: Refraction of Light on Metal Coatings
Вставка
- Опубліковано 19 вер 2023
- SILCA In this fascinating video, join SILCA’s Josh Poertner as he unravels the intriguing world of light refraction on metal coatings. It all began with a frustrated customer who claimed that SILCA cleaning products transformed his sleek black spokes into a brownish-purple hue. Thankfully, Josh's friends at DT Swiss came to the rescue with an enlightening answer: oil changes the way light is reflected, unveiling a glossy black spoke.
But that's not all! The same color-changing process also affects Sicuro Titanium Bottle Cages, where even fingerprints can alter the colors on these cages. Join us on this illuminating journey to discover the secrets behind this phenomenon and learn how to restore the original beauty of your favorite metal objects.

Very interested in seeing the colors change as voltage is increased while anodizing titanium.
would love to see the anodizing process!
Unbelievable that you actually went into this. I have these spokes on my DT Wheels and was wondering about this for a long time.
Love it! Yes, please show the anodizing process. Thanks!
I wish my life was going so well that marginally discolored spokes pissed me off🙃
Spot on
I don’t think it’s about being pissed off. I think it’s curiosity and fascination of why things are the way they are.
@@junibee492 Josh opened the video by saying it was instigated by an "angry customer".
@@theantichrome9842 valid point. I was thinking of this video from Josh’s perspective. I completely forgot that he started digging into it based on a complaint. Josh always presents well for spinning a problem into a scientific solution. Probably why I enjoy watching his videos.
Or so poorly that the only thing that makes you happy is a good looking spike?
Of course we want to see it (anodising titanium)!
Josh, surely you already understand that anything you wish to show us about how Silca creates its products, we will very happily watch, enjoy, and learn from! Maybe before you show us Ti coloration processes in production, you could create the Rule of 105% part 2, please, please, please, please, please? I just raced over 122kms with Conti 5000s in 23mm@109% up front & 25mm@103% out back on U21C rims running at 95/83psi with great comfort and grip after years of 23mms@105/110psi on V17C rims @
Very interested to see how the titanium cages are anodized!
Your comments about voltage and resulting color ngwhen anodizing titanium were confirmed to me by the Moots rep who was in town doing an event recently. He stated that the process of anodizing the various colors of Moots logos on their titanium frames includes a schedule of voltages that they figured out over time to achieve the different colors they offer. It was fascinating to learn about.
Really interesting. Would like to see the anodizing process.
YES! This was perfect. I know of this from the effects of different liquids on powdercoated surfaces or other steel components. It's amazing how much that changes the appearance of materials.
I have anodized some titanium parts at home, but still would love to see it on the Silca channel.
Thank you Josh, Appreciate the information.
I was fully expecting the end of the video to tell me I'd save 1w if I left the spokes brown vs oiled and black. Guess it's back to training.....
Amazed that you didn’t know this. I was told this as a kid 35 years ago
Great to see the curiosity to investigate! Made me do a literature search and learn about thin film oxides, and how the Voltage affects the phase interference of light due to thickness of the oxide layer. (Cite: Simulation Technology for Titanium Oxide Layer
Interference Color)😅
This is the craziest thing ever. Amazing issue solved!
Definitely want to see anodising titanium please 🙏
SCIENCE! I wonder how do big companies makes anodizing consistently? Im just guessing that they've fine tuned it for the specific voltage, but still im curious how does it look like compared to a DIY.
Very Cool!!
Would love an Anodize video. I've seen backyard aluminum before not production Ti.
When will Silca add "Spoke Oil" to the product line?
Do the video about colouring titanium!!
I'm sure this will make me look very clever in the shop one day.
Definitely do a video of the TI anodizing.
I was wondeing how refraction of light would slow us down! Lol
Would love to see that process
Please do a video on anodizing
That was neat
Ti anodize vid? Yes please!!
I saw the video title having "light" and "marginal gains" and thought to myself...'wait, using Silca products can help me approach the speed of light...yes please!" Alas, not quite that exciting, however, a fascinating presentation!
That would be a marginal gain for you?!? I need to up my game :-)
lets see the titanium anodized!
Yes plz
Amazing! Is this also why some DT Swiss spokes start squeaking under load and they recommend to apply oil or grease?
Hey Josh, count me in for a anodizing Ti video, please.
Can you do ti anodizing of 3D printed components eg the new hanger? If so, please add that to a ti anodizing demo.
I've just watched this video again. This time, I was left wondering if the surface coating on our spokes may also influence their aerodynamic properties? These parts happen to be both some of the fastest and slowest moving parts on a bike, and any aero influence could allow for another actual performance related marginal gain. Any thoughts? Any such testing in regard to such effects on components?
I'm currently waiting for my Pegatin Plus, individually cut frame/name stickers to arrive. I've pondered if placing them along the sides of my seatpost, or any other near vertical bicycle part, could work like the 'ribs' on the sides of your aero socks? UCI rules aside, that is, of course! If so, do those with the longest names potentially stand to gain the most?
Happy New Year to all as well.
Now I know why my Sapim Cx Ray spokes look weird
please show anodizing!
Pro Tip Nobody talks about: Due to the conservation of energy, if you aim your 5 watt bike light backwards instead of the normal forwards, not only does the light shooting out the rear of your bike make you 5 watts faster, but the 5 watts of light hitting the competitors behind you bounces off the guy half wheeling you and slows him down by 5 watts. It's science! Watch out for people wearing mirror jerseys though, unfortunately they're impervious to this scheme.
This is also why I live east of my work. Speeds up commutes.
Let’s see you anodize some stuff.
thats why I clean my rims with wd-40 on a rag
Nice, now I have a use for my Muc Off lube 😂. And, Yes love to see the cages anodized. More knowledge is good.
😎
Hey ! Can u make a non UCI rules pair of socks for triathlete 😊 ?
Ask OLLIE @GCN 😀
Love the vids Josh but you have the terminology wrong here. The correct word is “reflection”. Refraction is the change in direction, and speed, of a wave (e.g light) when it passes through the boundary between two different mediums (transparent or translucent materials in the case of light waves). For example light travelling from air into glass will change direction and reduce speed as it enters the glass.
This appears to be due to thin film interference, which includes both refractive and reflection (diffuse and specular). Source:" Simulation Technology for Titanium Oxide Layer
Interference Color"
@ccatwood beat me to it, but the color shift is due to both refraction and reflection effects in the oxide layer either cancelling or reinforcing the wavelength of the light that is reflected.

So throw motor oil on my spikes?😅
yes, but where's the gain? the watts saved? 😢😂
