@@trulyinfamous No, copper isn't the only metal that does that. The whole reason stainless steel works is that the other metals in the alloy form an impermeable passivating layer. Aluminum also.
For the car poor surface prep, plus did not strip down to bare metal and completely cover with a chemical rust converter to make the oxide a more durable phosphate, and also do the same on the inside of the vehicle as well. First remove the rust, make the material chemically clean, and passivate with a thin chemically bonded coating, then apply the primer, make smooth, then apply the correct automotive paints, and finish with the clear top coat. Has to be done both top and inside, though the inner section under the lining you do not have to bother with looking perfect, so it is faster there.
Part of the problem is the fabrication process is performed in oxygen filled rooms so the pieces always have a base coating of oxidation. Producing the pieces in facilities filled with inert gases or in a vacuum would prevent that problem and prolong the lifetimes of coated metal pieces.

Here is an interesting tidbit on rust that wasn't mentioned here that makes replacing really old infrastructure a bit more complicated. Metal made before the 1940s was much more resistant to rust. As an unforeseen impact Of the Manhattan Project + all other subsequent nuclear testing and the improper recycling of affected radioactive metals, the resistance of corrosion metals have compared to before the 1940s is greatly reduced
The process of bluing metal; in particular gun metal may be of interest to you. As I understand it, the process rapidly oxidizes the surface layer then converts the red iron oxide, which is soft and highly porous to black iron oxide which is more like a ceramic material. In general it's a type of surface passivation. Several non-corroding metals like aluminum are actually highly reactive -- much more so than iron but upon contact with air they naturally form robust surface passivation. In the case of aluminum the passivation layer is essentially sapphire so even a few nanometers is enough. Salt (chlorides actually) or alkali can still attack it though.
I'm wondering the same as some people already mentioned why don't we make more use of metals that don't rust. Or use more materials that are not metal such as: carbon fiber, graphene, or thermoplastics / thermosets examples polycarbonate, fiberglass.
Maybe some day we will find an element or chemical that when mixed with Iron will make it really rust proof. We can only hope and experiment. Thank you for that very interesting video!
Why do some iron alloys are more prone to rust than others when neither is stainless? I have a meat grinder with a replacement bolt for holding the handle in place. If the bolt gets wet it rusts quickly, but the rest of the grinder doesn't even in places where any coating has been rubbed off.
No, too many big players who want to keep the status quo intact. Short term good for them, long term your grandchildren will be the ones having to deal with it, with those that profited from it either long gone, or wealthy enough not to care.
I expect that we will still need cars and such for industrial purposes even if - do we call it "domestic use?" - anyway, whether the average person has a car or not, they're still going to depend on trucks that bring in food to their grocery stores, and public transit of many sorts still relies on gas powered vehicles. Reducing our reliance on such vehicles is certainly a goal worth pursuing! But it's never going to be possible to eliminate it, I don't think. And in the case of the USA in particular... there will always be a big need for things like the Interstate system. Without that, I think about half the nation would be almost inaccessible... Certainly the Interstate and State Highway systems made every single one of my summer trips possible when I was a kid out in western Texas. And later, those roads made it possible for my family to relocate. With all the costs and problems that come with roads, it's also undeniable that we NEED them. And it might be one of those questions - "the chicken or the egg" - did we become dependent because we had the roads, or did we create the roads because the need was already huge and it just didn't go away? Or was there some confluence of issues and events that joined forces as it were, and put us in this current situation? Lots of factors contribute to this and I am really glad that these videos - this whole channel - provokes questions like yours! It makes me happy to think on it and see that there are possibilities alongside the problems.
@@Beryllahawk I do agree that cars will have to stay part of our infrastructure. The thing I was mainly speaking of was car dependence. I can get groceries on the bike and get there in 5 minutes. I can also get into the city to go to work by bike. If the weather isn't great I take the train and a bus though. But to visit family somewhere else in the country I'll use the car. If people do their daily commute by public transport or other means of transportation then there will be way less cars on the roads. This makes everything more convenient for everyone. Having cars isn't a bad thing. They're really practical to move stuff and to get to places quickly. But having too many of them and being dependent on a car to do practically anything (as is the case in the US) then it will make everything very inconvenient. City Beautiful and Not Just Bikes, along with some other channels, made videos that answer your chicken and egg question. It is a lot more complicated than the few questions you've asked. It even goes as far as racism. But most of it is about bad city planning. Many places in Europe have a big focus on cars, but aren't car dependent. Not everyone can afford a car or can use a car, so making everything car dependent is not an option here, and I think it shouldn't be an option anywhere. Anyway, it's very late and I'm tired and rambling. So i'm sorry if I don't make any sense or if I misunderstood some things you said. Hopefully I can think a bit better tomorrow xD
The U.S. puts a lot of local control on municipalities, so it will only ever go car-independent town by town. And zoning departments are notoriously sclerotic.
Why is Zinc used as the coating? Aluminum makes a self passivating layer, but I wonder if it doesn’t make a good contact? I also thought that steel alloys with chromium are rust resistant, but is this false? Thanks for the great videos!
Zinc is used because it is easy to deposit onto surface of steel and steel alloys, and it is a reactive metal that forms an oxide coating as well. You do get aluminium coated steel, but it is a much more expensive coating, as you have to apply it in an inert atmosphere. Zinc you can apply to clean bare steel in an open bath, either by immersing the cleaned and acid etched steel into a bath of molten zinc, or by using electrochemistry to apply it in an electrochemical cell from a zinc anode, using a zinc chloride in water solution. Aluminium you can do neither, the melting point is too high to have it out in the atmosphere, as it will catch fire, and in water it is too reactive. Thus you have to apply as a coating via sputtering in a relatively high vacuum, running a cleaned steel sheet from a roll to another in the vacuum. Chrome and it's alloys with steel work, but rely on the formation of a chromium oxide layer to passivate the surface. Thus stainless steels, but they are all slowly going to corrode as the thin surface layer wears, and are not really suited for salt water use, or near the ocean, as the saltchemically reacts with the coating to dissolve it with time. Any chloride will do it, so even road salt will slowly erode it away.
1. Metal doesn't rust. Only iron rusts. It's a form of oxidation. 2. There are metals that don't rust, or don't even oxidize under conditions in which iron would rust. We call those metals PRECIOUS METALS.
Look to give you guys a heads up. Rust is a very slow reaction so you know it’s only really a problem if you live at the coast then you need to put some prevention in because Rust will build up very quickly, but if you live in dry areas and inland, you can have bits of steel outside for a few years and it only just damages the surface layer I’ve got big steel plates that are 2 inches and 3 inches thick and they’ve been outside for a few years and they just got surface rust layer of discolouration but no major penetration damage of the rust probably less than 1 mm if that it’s more the appearance of the plate looks awful. Also guys it depends on the thickness of the steel see when it comes to stuff like cars they made out of paper thin metal. They rust through pretty quickly once it starts in a matter of a year or a few years depending on the environment, you live at. Also ships that sail across sea once the paint layer Wears off or the zinc. Bars have corroded away Steel Will Rust pretty quickly to? But in reality, if you have blocks of steel outside in your backyard and you live in inland Australia or inland in a country that you live at Rust is not going to destroy the block of steel in your lifetime it’s such a slow reaction. Also, iron and Steel are pretty much almost the same thing. Steel is just the alloy of iron. It’s just a little bit of carbon added to iron and small traces of other metals to depending on the grade of steel.
I've actually been doing research on sickle cell anemia because the mutated hemoglobins become hydrophobic causing water to be repelled this in turn makes the iron unable to attract oxygen which in turn causes the person with SCA to not have the proper blood oxygen saturation I feel if we could replicate what causes those spacific cells to do this we could not only possibly find a way to treat or cure SCA but also a way to synthetically make this chemical and apply it to steel and iron objects my other ideas to combat rust involves a vacuum chamber filled with oils and forging these steel or iron parts within these high pressure oil vats but the latter choice would be extremely dangerous

It's not yet feasible because of cost. And carbon will decay in its own way, it also has different properties than metal, which does not automatically make it the best option (think heat/cold resistance, ductility and elasticity, shock resistance, etc.)
