I like how you left the mistakes in the video and explained what happened. Most YouTubers only show the perfect take and don’t ever explain what could go wrong. That’s frustrating to those of us trying to duplicate their results.

Just so EVERYONE is aware this is ONLY the process for titanium. That was important let me say it again. THIS IS ONLY FOR TITANIUM!

Aluminum anodizing is not done with just an electrolyte solution. Aluminum anodize is done in a sulfuric acid solution (the strength of the solution is usually proprietary to the company). The temperature of the solution needs to be held in a specific range or you risk burning the part. In Aluminum anodizing, Type II is a weak basic electrical and corrosion resistant coating (Almost every plating shop does this type). While type 3 is basically case hardening of aluminum (rockwell 60 to 70), which also provides an electrical and corrosion resistant coating (You need a specialized shop generally to get type III as it's much more difficult to do).

Thanks leaving the "failure" in and explaining what went wrong! Super helpful

One thing worth mentioning is that the copper wire you were using is enameled. this type of wire is used to create coils for transformers and motors. the enamel coating insulates the individual windings from each other, so unless you sand it off (like you seem to have done at 1:45) you probably wont get a proper connection. The other thing is that the current will prefer shorter parts through the water, which is why the bigger part only partially anodized. The pedal was smaller, so the difference in path lenght wasnt as big and you got a more even coating.

My wife is a robotics and engineering middle school teacher and I love sharing y’all’s videos with her to show her kids and keep them interested in engineering

38 yo and I just learned today that you can stack 9 volt batteries like that. Thanks!

Very interesting. I am the lab lead at a chemical processing plant where we do multiple types of anodizing. Type II, Type III hard coat, Boric Sulfuric and Chromic anodize. Neat to see similar applications done at home.

Am i the only one that doesnt have titanium parts lying around to do this?

[I-Libertine]

I tried to anodize my own parts, but the clips hurt too much.

Also for the big part, More cathodes around the Bowl for consistency. Energy travels straight, so try and get a bowl deep enough to have the sides of the part with the most surface area facing the cathodes. If it matters.

[dakotareid]

You should change the title to titanium since this won’t work with aluminum

[BRK_NYC]

I love how they teach you, and joke around. It makes the video more interesting and fun to watch.

[peterreeves]

I know nothing about machining and only ended up here because I want to anodise some Aluminium parts, but boy am I glad I watched, that is one of the most entertaining videos I have seen in a while and I learned something. Absolutely love the presenting style great work

I just turned 18. Have been working on my own cars since I was 11. I just want to say thank you so much for this channel and al I can learn. Subscribed 😊

As much as I do like this your DELIVERY of said content is priceless! 😂

Reverse polarity and it removes the material from other sample, then toggle polarity back and forth... Aluminum works well with copper coins for example, but silver works well with most metals...
Also the spectrum of color is broader if you vary the voltages instead off being limited to 9 v increments with using batteries, a good DC power supply that is a Variac with high amperage at low voltage will give you consistant end results.

[jeremymatthies]

NERD!!!! 🤣🤣 That had me going. You guys crack me up with all the shenanigans and fun you have while filming and working you do. Nice job on the explanations Barry. Looked like a lot of fun and troubleshooting for you.

[silvercrxsi]

I use simple green instead of the water/baking soda mix with good results, also using an adjustable power supply let’s you fine tune it to dial in the color better since 9v increments is a pretty significant amount

[machiningmoments]

Can this be done with any metal? Aluminum? Can the anode and cathode be a steel rod? Thanks for the video.
