My first job circa 1982 was in an architectural metals factory where they anodized aluminum parts for buildings. Popular because the end product was light, easy to shape and provided excellent protection from the elements. If I walk around some part of London now I can still see parts we made on places like the Chelsea Harbour development.

this was a fun watch, when I was roughly 20-21 I used to work in an aluminum anodizing factory and it was one of the few jobs I would go out of my way to learn the science behind because anodizing the multiple ranges of colors and depths we could do really intrigued me. hot dangerous work, but scientifically amazing!

While it is true that rust is the oxide of iron, you need to remember that Bill is talking to the masses. The masses are not into the finer points of corrosion. Bill is just trying to get a concept across in a short video. So, try to cut him a little slack and let that slide even though it grates on your more precise tendencies.

Yes, most people don't know what oxidation is, but everyone knows what rust is. This could cause future confusion with people that are really trying to learn how things work. It would've been better to say "it's similar to rust" or "sort of like rust". This isn't a criticism, I love Bill's videos.

Actually, that’s not quite true guys. While the term is mostly used for iron and steel corrosion, rust is often used to describe similar action on other metal surfaces. Look it up, and don’t make assumptions.

I live on a sailboat. After paint failed on some aluminum fittings on the boat, a rigger friend recommended that I black anodize the parts which I did. When I brought the anodized parts to the boatyard, an old timer friend recommended that I coat the parts with lanolin (sheep fat) which I did. The lanolin seals the pores and keeps saltwater out. The anodizing protects the aluminum. More lanolin is re-applied when the parts look a little chalky. It's a little pricey but the anodizers usually charge per batch, not part, so plan accordingly.

Which is why the AR rifles introduced in the mid 50's by Armalite were so advanced. Armalite used manufacturing advances it took from it's parent company, Fairchild aircraft. The anodized aluminum upper receiver is harder than the steel bolt carrier that reciprocates inside it. It's the steel carrier that wears out first.

robert karas No, not really. The AR-15 can be cheap if you want a cheap one. The anodized aluminium receiver isn't the source of failures or low accuracy in cheap rifles, or in expensive rifles, or in any rifles. The smaller parts that require high precision tools to manufacture typically fail long before the receiver. From an engineering standpoint, the AR-15's receiver is excellent: it's durable because of the anodization process, rigid because it has relatively thick walls and still lightweight because it's made from aluminium.

I have always loved anodizing- racing BMX bicycles as a kid the coolest looking parts were anodized.

Exceptional video. it told me exactly what I wanted to know regarding WHAT anodizing was, but what to expect. Thanks for for such a complete, and easy to understand explanation!

As an interesting note: Type III aluminum anodizing (sometimes called "hard coat") has a surface hardness similar to steel. With Type III hardcoat, you can have the weight, rust-free nature, and cost of aluminum matched with the hardness of steel. While this doesn't have much use from a structure perspective, it works great for sliding pieces as the finish will not wear off easily like bare aluminum or Type II anodizing (standard anodizing) or show scratches from normal use.

I love those videos. Wish there were more of them coming.

I've noticed anodizing is used in cookware. I'd love to see Bill present the different surface engineering of cooking materials to explain their different properties.

I will not lie to you Bill. Sometimes I click for the music.

1:43 This is also the how pearlescent pigments are made. A layer of TO2 is deposited on very small mica (or borosilicate) platelets so the color is produced is by the thickness of the layer. TO2 exists in two crystal types, Anatase and Rutile and they give different results.

After seeing the last video he released, I bought his book, and really enjoyed it. Recommend others do the same, many more interesting stories, and things to learn about our everyday life.

You carry on where popular TV shows came to a halt almost 20 years ago, replacing things like this with cheap and revolting persuasion techniques like ridiculously deep voices, extatic screaming and camera shaking describing what is essentially bad science. This is awesome. Keep up the good work.

Oh another great video, Just about to read this chapter tonight.

I went on a field trip to a plant that anodized aluminium. The plant was very professional to the point that everything was clean, so clean that their vats of acid was crystal clear to the bottom of their four foot depth. It was like looking at pools of clear, cold water, and to my dismay I felt an urge to put my hand in there, luckily my fore brain kept control and I took the idea of working at such a place off the list.

Many, many years ago, I worked at a company that made photosensitive plates for printers. They took huge reels of aluminium of varying thickness, pulled them through a 30 yard long bath and used huge currents to anodize the material. Controling the speed and current controlled the thickness of the oxide layer. It was then coated with a photo sensative layer. After exposure and developing the plates, the pores that were not closed by the remaining photo sensative layer take up and release the ink on the paper. Clever stuff.

I love the way this man speaks, often modern science videos have a "whhoaaduude" tone to them and don't really get the point. His videos are quite the long due throw back to the informative, straight forward, information videos you see from the 1940s-1970s. Really refreshing.

Dear Bill, your video is very fascinating and easy to understand for students as well as professors. I find it yesterday and going to show my student today in the course of surface engineering at UQAC. I am running a project on anodization of aluminum but use cathode in the same acidic bath. However, in your video I did not understand where did you put the cathode? Secondly, can you find a condition (playing with thickness as well as metals) that your anodized layer hence the whole material become invisible? ha ha ha!!!

Creative video to understand engineering concepts

Thanks for sharing this knowledge~ With you, this world is becoming a "brighter" place : )

I'll definitely be buying the book!

1:35 I was a welder for 5 years and I always loved the beautiful colors when joining Stainless Steel. Now the dummy answer they give us when teaching TIG welding is it's oxidizing (despite the argon shielding gas we use to prevent oxidation and the nickel and chromium). It follows the same pattern of a light hay color through the red blues and purples. Can I make an assumption about how much penetration I am getting based on the color of the weld? Is this the more detailed answer of what is happening? I don't have a ton of experience welding Aluminum but I have done it a handful of times. However I have never seen the color change on aluminum. The procedure is much different we use AC current and a pure tungsten electrode that we intentionally ball up instead of sharpen to a point.

Very cool. Love your videos

I used to work at an plating company doing aluminum anodizing. There were two types of anodizing they did, soft and hardcoat. Two different processes. Only soft anodizing will accept the dyes. Hard anodizing would be either natural which are different shades of brown or dyed black. Bill explained it better than my former boss. Bill, do a hard anodize episode for your fans.

@WeighedWilson

Thanks for this.

I never knew that. Awesome.

you know this is an old video when apple is being called durable

One thing that is interesting to note is that anodizing and alodining (a similar chromate conversion process) are the basis of corrosion resistance used on all aluminum aircraft.

The book is really nicely written, you should check it out. Of course there is an e-book version if you don't like dead tree.

This video has sealed the deal, I'm going to get the book. ....done. I do cold metal casting of resins. I have a silicone mold of an item. I will sometimes brush in powdered aluminum to the mold so that the liquid resin will grab that and have an aluminum coating that is bound to the outside layer of the resin. From there I can use some steel wool and give it a very real brushed metal look. This video makes me wonder if I could try and anodize it at all. I'm not sure but to have a colored aluminum finish would be great for the decorative pieces I cast.

You don't want to anodize that because it's not pure metal. The resin might produce a nasty reaction. You could try just coloring the aluminium powder with alcohol dye, let it evaporate completely and then coat your mold with that powder.

To give an idea how fast the oxidation effect is. When we weld aluminium and we brush the oxide layer we have bit less than 10 minutes to weld or we need to brush it again.

I sincerely miss these videos...

this guy is amazing

=) Had no idea what Anodizing was.. now i do. Awesome process.

Fascinating!! Well explained!! Can you anodize copper, or tin to change it's colour??? (I'd like to make a rainbow PCB!)

@MrAluminox

7 жыл бұрын

By anodization no. Tin there is nothing to do. Copper by controlled heating and cooling like some steels or oxidation by chemicals. There are plenty on infons in Internet.

So putting it very basically, ignoring specific steps and materials, you run a current through the metal you want anodized, which 'primes' the metal with a coating that is ready to accept a dye to intensify the color and finally, the finish is sealed by boiling the piece to lock in that color? I don't know why, but 20 years ago I missed a program on Discovery Channel, and never tried to find out, but it kept gnawing at me to figure out why things like carabiners came in various colors. Now, 20 years later, I can sleep well knowing how it's done. Bless you Bill - my sanity is partially saved! 🙏

What do you use to add color ? How do you control the specific hue and value ?

I wish you would've taken a pair of calipers (micrometer) to measure (any one) dimension(s) of the Ti strip before and after the anodizing, so we at home could in fact see that there is something being added. Otherwise, phenomenal video. I tip my hat off to you.

Awesome i always wondered how they anodized aluminium. So you mentioned the two wave lengths of light cancel out. Ive always wondered if it would be possible to totally phase out 2 light beams. lol i wonder...

Delightful video illustrating great engineering. Consider doing a video on engineering humane, healthy workplaces. I've experienced dangerous building air quality problems (poor engineering), repetitive stress issues (solved with an ergonomic, programmable keyboard, which is good engineering), and dangerous air pollution in Los Angeles because of failure to engineer transportation intelligently for a rapidly growing population, I see repeatedly why we need great engineering to save lives.

cheers Bill :)

Nice video but a small correction: with aluminum the current doesn’t “push” into the aluminum to make channels, the process is actually chemical. What’s missing here is that you anodize in an acid, typically diluted sulfuric acid. The anodizing process is a tug of war between the acid that keeps digging holes and the current that keeps forming oxide. Where the acid is winning, you get the long empty tubes, where the current is winning, you get the oxide walls. Without enough acid, you never get past the nanometer thin barrier layer. Without enough current, the acid eats away all the oxide. Keeping everything balanced is the hard part. Love your channel!

Good Job.!

So since certain colors are a thicker layer of oxide, those colors are more durable than the others?

seriously, i want this guy to teach me chemistry. far better than the damn boring class i went though in high school.

i love these videos :)

Telling the whole history of aluminium would be interesting too!

Is there any way I could download/purchase a copy of this video clip?
