Thanks!! This clears everything up for the stuff we're learning in chem!!! I find it's these practical "how to" videos that helps me understand the concepts more, rather than those that only teach the concepts and nothing practical.
Well done! I'll be sharing this with my 2CV friends (a basic French car that rusts if un protected. Thank you for making!!! Next on the wish list is basic video on how to set up a galvanizing business to rust-proof 2CV bodies (tall order. I know; maybe someone will see).
@shodanxx 1. depends on current density, 2. not really, 3. depends on concentration, temp and agitation, 4. depends on conditions, 5. wears out, 6. more information on the composition required before i can make an assessment. 7. There is no 7th question.
@CowOverTheMoon research a topic called "overpotential" to see why zinc comes out. And the iron does not become Fe2-, it just gets a negative potential. The copper wires in your house don't get Cu2+ or Cu2-. But they do get charged with electricity.
@xBeyondInsane Rust is iron oxide. When iron is exposed to both air and water, an oxidation-reduction reaction occurs, and rust is formed on the surface of the iron.
I have a galvanized chain link fence. Over the last couple of winters, "freeze heave" has pushed the posts up 6". I want to put a galvanized bolt thru the bottom of the post to prevent that. Will the bare steel drilled hole appreciably diminish the life of the post? Perhaps concrete too, but not sure that is such a good idea? Thanks for all the videos!!!!!
@@yash_arI doubt it but it would protect it better than nothing but eventually I would think it would rust internally but it problably doesn’t matter as it’s sealed from water and oxygen so I’m thinking no but I know rust still spreads so hard to say…
NurdRage The white powder is called wet storage stain, or white rust, It's because you didn't give the zinc time to oxidize before your saltwater test, The galvanized nail would have performed much better if given the time to"dry" I'm more experienced with hot-dip galvanizing, but I know the look, thought you ought to know.
@@usmanahmad1788yes but I recomend if there’s any broken motor mounts can mounts etc anything that needs welding weld it up and fortify tf out of it cus you can’t weld zinc unless you grind down your coating where you want to weld but then that spot can rust so weld everything before galvanization and it’s better to do in pieces for example take the body and drivetrain off your frame and send it in pieces
2 questions. Hydrogen ions are discharged easier than zinc ions. But why is zinc still discharged? And when you say iron has a negative charge, does it mean that its Fe2- or something? Thanks in advance. You'll be a great help in my chemistry
I am addicted to your videos they are fun to watch and very informative. I have a question, can you remove zinc for hot dipped galvanized steel? I have read on web that is very hard or almost impossible to do without melting the zinc off
So if I want to build a wooden fence held together by nails the zinc crust will keep the nails safe on for a long time (like a year or two) ? is it worth the effort or is it cheaper to buy already galvanized nails ?
could you make a video about how to plate stuff with other medals.. like silver, copper, brass, nickle, aluminum. or one about how to make an extremely strong electro magnet
@NurdRage thanks for the concise answer I will get back to you with more information for #6 "5. wears out" do you mean that this method will fail due to mechanical wear more than hot dip galvanize but that this method is as effective (for the same thickness of deposited zinc) for corrosion inhibition
Nice way, So if i have more parts amount and bigger parts, should i have more current ? Should i wait more ? Should that piece of plate be bigger ? Should i change the cable into a bigger one ? Should change the zinc liquid often ? Thanks 🙏
I have hypothesized that if the surface of the metal to be galvanized were etched with tiny striations, those little scrateches would fill with zinc. In effect I think that the initial layer of zinck could not only be thicker (if the striations are all spaced out very close and such) but also more durable. There are many different kinds of electroplating, some like vandium/chromium and such are done to make surfaces harder and more resistant to scratching.. yet all of them wear out.. .
The principles described here also apply to boat hulls. There are large (or small) zinc blocks attached below the waterline of a boat as a sacrificial metal. They are more reactive and thus keeps a protective bubble (so to speak) around the boat.
@aCagedApe this is exactly the problem, wood doesn't but a layer of iron or aluminum poweder would. what i want to know is the result of such experiment, how hard or stable would it turn out.
I made a steel ring in my shop class. I love it but the issue is it keeps rusting and I have to clean it. I'll give it a nice good polish and give this a try!
noble metals are noble because they don't normally oxidize, silver will tarnish because of sulfur and copper will form a patina, and along that notes iron forms a patina just like copper but the carbon in steel makes it flake. gold doesn't react to pollutants in the air or the ingredients of normal air which some people believe is why it's so highly regarded. is it possible to put a zinc coating on noble metals? as long as you have a sacrificial anode of zinc and the zinc sulfate it'll work.
so fulll of win, what a channel you have! Is there a way I could extract caffeine and then eat it or snort it without ingesting toxic materials used for the extraction? Thaks good sir!
How well does this zinc galvanization reacts to mechanical stress? I'm aware that it's a coating, not an alloy, but to disdress or peel away the coating do I need a file/sandpaper or is enough handling the item for some time?
zinc sulfate is used just just that solution would conduct electricity? I've done some zinc electroplating experiments in past and it works even for example with ordinary table salt (some sugar and acid improve results also).
Very cool. Reminded me of a video about colloidal silver production. Have you had any experience with colloidal silver? That would be a fun video that would sure stir up some discussion and views!
thank you for the video! defiantly something new for me that I didn't know and after thinking about it, this leads me to the following question: is it possible to apply this to anything else but metal? I have carved sculpture out of wood and I would really like to give it galvanized look. i was thinking to paint the sculpture with iron powder and galvanize it? will it turn to solid surface or will it break off?
There might be some arrangement of circumstances where you could convince wood to be electroplated, but as a rule you need a conductor that can easily give up and accept electrons, and wood does not do that. For the most part, metals are the only materials that meet that criteria, and not even all metals(gold comes to mind).
Tap water or distilled, does it matter for this? Could we us 12-14 volt battery? If yes do we lessen amount of time in solution? How do we know it's enough time when doing larger pieces?
It's to do with current density and not the potential (voltage) the greater the area to be plated the more the current. Pushing the potential too high increases the risk of hydrogen embrittlement and other forms of hydrogen damage. the carbon content of the nail also plays a part in the risk of hydrogen damage (especially in high-strength steel components) Electroplating is just okay for corrosion protection but the layer is very thin typically and thus will not last as long as hot dip galvanizing (HDG). When one does HDG you find that there is also diffusion of zinc into the surface of the substrate being treated... in fact there are varying distinct layers of surface alloy layers with different zinc/iron ratios. You can also get thermally diffused zinc surface coating (called sheradizing) where the protective layer is purely zinc diffused into the surface of the substrate. Additionally one can also thermal spray molten zinc globules onto the steel surface. HDG and TDZ both have elements of zinc diffusing into the steel surface whereas thermal sprayed zinc and electroplating does not. Zinc (in our normal atmosphere) tends to react with the moisture, oxygen, and carbon dioxide in the air....however, in most locations it takes typically around 5 to 6 months to form a complete protective Zn(CO)2 surface film over the zinc (in very aggressive environments this can be too late and corrosion under such circumstances could eat it up for breakfast as the saying goes, before the protective Zn(C0)2 layer has even formed (typically a temporary chromate layer (now banned in many places for being carcinogenic) is applied as a 'passive layer" to help protect during the first 6 or so months of exposure.) Zinc has two mechanisms to protect iron/steel to which it has been applied and the one is a barrier that the Zn(CO)2 forms on the surface (it seals off the underlying surface from the aggressive environment) and secondly by a technique called sacrificial anode cathodic protection where the zinc corrodes providing electrons for the cathodic reaction that occurs simultaneously and thus it prevents the cathodic reaction from taking electrons from the protected substrate (steel) thus protecting the iron/steel from corroding. Anyway, enough lecturing on my part.... lol
two silly questions. is there any significant issue by using tap water that may be hard? And what happens if the solution you made of zinc sulfate and water is more diluted than 30grams per 100 milliliter. Will it not galvanize as fast, as well, or not at all?
would it be possible to hook up the negative lead of a battery to say an iron bar and the positive end to an antenna to give the metal a negative charge? i kinda want to try that, i think i'll do the same test you had, two nails in a salt solution, only i'll have one connected to a batterie's negative terminal. just for kicks and giggles i might make an actual circuit by hooking a battery up to a capacitor and using the test metal as a connection between the two...
Hello, what is the best method for galvanising a car part? What is the difference between diffrent solutions eg. with zinc chloride vs. vinegar&washing soda? Are these affecting quality of plating? Thanks
are there any advantages of using your solution or using ammonium chloride & zinc chloride as a zinc plating bath? Your solution appears easier to obtain
I saw a dude use water, Sodium Bicarbonate (Arm and hammer super washing soda), and pickle juice. He didn't even filter the juice, and there were even pickles still in the jar!
if you make the zinc plating thicker, will it last longer or just flake off if it's too thick ? is there a way to passivate the zinc coating to stop it from corroding ? what is the ideal voltage/current per cm² for plating zinc ? is this plating method as good as hot dip galvanize ? I found a "self-etching" galvanizing primer, I applied an even coat on the engine bay of a car but after a few months surface rust started poking through, how come ? and what is this etching exactly supposed to be ?
old video but you could have used steel wool to remove the gray crystallized zinc and reveal nice shiny zinc. you could then show if it oxidizes easier or not compared to crystallized version because of the increased surface area of the zinc crystals.
DR L I witnessed an associate of mine take a piece of aluminum foil dip it in a liquid and fold it and have it turn too hot to hold can you explain?.....u can contact me for more detailed info
But how can i get a much smoother and good looking surface after galvanizing? I'm going to make a part for a guitar which I need to protect and has to be a very good looking part to.
@ThisNameIsNotProfane Just turn on the annotations by pressing the rounded rectangle with "CC" in it. Would this work in galvanizing something copper, such as a penny, to make it silver?
It won't. The electrolite acts as a resistor. If you think about it, a light bulb should short out the mains power because it's basicly a swirly wire and nothing else, but its resistance is to high for that to happen. The same goes here.
DR L I witnessed an associate of mine take a piece of aluminum foil dip it in a liquid and fold it and have it turn too hot to hold can you explain?.....
I have a question. If I galvanize metal bolts and wing nuts and the nuts will be removed from time to time. Is the galvanization on the bolt and nut threads going to be worn off and rust again?
@thetommantom metal cutlery uses stainless steel, not galvanised metal.. can't comment on the battery part; don't know what batteries taste like, and don't intend to find out.
So I am wondering, if someone chemically needed zinc, could you do by putting a load of galvanized steel into sodium hydroxide solution? if sodium zincate is what you needed that is.
@aCagedApe my expirience with such metallic shinny paints is that they don't react. therefor leaving it outside for a week wont do anything. this is why i am looking for an alternative solution to my problem and i am hopping that someone can confirm that galvainizing or anodizing would do the trick.
non.... in industrial the method is to fill a big tubs with zinc heated and maintain at 450 degree (liquid state) after you put your metal in it.... this method will not just plated your metal but create multi-layer of metal/zinc like a chemical reaction.....
Even though I never do these experiments, they're always entertaining and informative to watch!
Sounds as if the narrator's vocal chords were galvinized

@NurdRage can u forge galvinized metal or do u only do that after the metal is already foreged?
I understand that Galvanized metal can be painted over, however, is there anything that needs to be done before doing so?
