I'm a blacksmith/blade Smith and I use beeswax. You heat the metal until it's hot enough to make the wax smoke. You wipe it on with a rag soaked in melted wax. When you wipe it on the waxed rag doesn't have to be hot, the wax will melt out of the rag onto the iron. It turns your iron black and seals the pores of the iron and coats it. Exactly what he's trying to do.

Linseed oil burning is actually a traditional method for rust protection, however you only want to dip the object quite rapidly in the oil before you pull it back up. This way you'll end up with a surface hardening in case you heat it to red-hot, instead of a deep hardening if you let it cool down in the oil. 😊

For sure one of the oldest methods, that's right. But it works different: You have to dip the object into the linseed oil. Take it out and THEN heat it slowly, until it turns black.

I learned a trick a long time ago while taking a collision repair course at an insurance institute approved university. Better and stronger than powder coating, you can use a rattle can of any paint color applicable for metal surfaces and spray one to two coats on the metal surface including bolts. Once it dries completely bake it in an oven or toaster oven at 275° F for 45 minutes to 1 hour. Let the metal object cool down to room temperature and you will have a hard paint coated surface. That is more durable than powder coating. It’s not magic.

You can also dunk clean iron in copper sulfate. This does a "replacement plating" process that puts about a one atom thick layer of copper on the surface of the iron part. It looks good but needs a clear coat to stay looking good. It is a way to make cheap stuff look like more expensive. It also works on aluminum parts.

Playing devil's advocate here, but I've sadly tested pretty much everything you've mentioned here in actual-world conditions. If you left those samples outside for a week, they would all have corrosion. Industrial plating or replacing with stainless hardware is the only way. If you are plating also, get the plater to heat the bolt's to degas after plating, which will help to maintain their structural properties. @dirtygarageguy has more on this and goes really deep into the science. On cold bluing, it does work, but it is also something that constantly needs to be maintained. That along with hot bluing. If done correctly with the correct chemicals such as sodium nitrite and sodium hydroxide it can also inhibit rust for a longer period. Still, as this is common with firearms it consistently needs to be maintained and I would say it would be impractical for the majority of automotive applications.
@jameshatton4405 9 місяців тому
How do you degas your stuff? Industrial oven? I used to work at a custom wheel manufacturing place, we used to industrial chemical paint strip, then sand blast, then outgas via oven on 400 degrees C, then we would powder coat. Do you degas after coating or before coating or both?

@@ivanyurkinov Unfortunately, you could legit test yourself, you'd have more luck just painting oil or a displacement product directly on the item, and it will stay rust-resistant for longer. Oxides, or what you are referring to as "Oxide finishes", are indeed plating or, at minimum Black oxide, which is Magnetite, aka a chemical reaction of sodium hydroxide and some form of nitrate. It would help if you also had a bonding agent to assist with the creation of Black Iron Oxide; only then can you actually impregnate the metal with an oil or wax. Before this, the surface of the metal, no matter what grade. It is not porous enough at the molecular level to accept a catalyst.

In the cast iron cooking world the process of heating up oil so that it burns/smokes (polymerization) and becomes a rust proof coating is called "seasoning".

You could also try rust bluing. Rust bluing is commonly used to blue firearms, particularly for period correct antique restorations. Clean the part up and get a coating of surface rust on it by applying a solution of salt, vinegar and hydrogen peroxide. Once the surface is rusty, throw it into a pot of boiling water for a few minutes, or put it in a steamer basket over a pot of boiling water. You may need to clean the surface up with a wire brush and repeat the process a couple of times to get a good even coat. Bluing in general is the process of putting an oxide coating on the surface. Iron has a large number of different oxides that it forms, the one we generally want is magnetite - Fe3O4.

Its when a boilers' ph goes too high, and the magnetite that naturally forms comes off and weakens steam/water lines and the flakes can plug downstream fittings. Instead of acid way, someone might be able to get a pot of water and caustic soda and boil their part until they get magnetite.
@phizc 9 місяців тому
@@justcraziii that is a legitimate way of bluing. It's what's called hot bluing or hot caustic bluing. It involves immersing the steel part to be blued in a solution of potassium nitrate, sodium hydroxide, and water heated to the boiling point, 275-310 °F (135-154 °C) depending on the recipe. But rust bluing is the only process safely used to re-blue vintage shotguns. Many double-barreled shotguns are soft soldered (lead) or silver brazed together and many of the parts are attached by that method also. The higher temperatures of the other processes as well as their caustic nature could weaken the soldered joints and make the gun hazardous to use. Source: Wikipedia That said, it's way more dangerous for us amateurs. The boiling caustic bath could easily cause nasty chemical burns, and if you get that stuff in your eyes, bye-bye eyesight.

Different oils have very different temperatures where they polymerize. For my cast-iron I use equal 3rds by weight of grapeseed oil avocado oil and beeswax. Melted in a pan and then poured into muffin tins. Polymerization temperatures is around 520 degrees Fahrenheit. For even preheating use an oven. You could drop hot bolts and parts directly into the melted mixture.
@5naxalotl 9 місяців тому
yes. imo it's a big problem that the polymerizing characteristics aren't being considered. the video focuses on the technique of blueing metal, and this has very little to do with what happens with the coating ... which is the thing that actually prevents corrosion, after you discount the very small protection from the thin oxide film. oils that polymerize probably need to be baked/fired onto the surface rather than relying on the brief residual heat during quenching; and things that don't polymerize (motor oil, paraffin wax, WD40) need to be explicitly treated as a residual layer. it should be noted that WD40 was developed as a corrosion inhibitor and is very tenacious about clinging to a surface despite remaining liquid ... the coating might not benefit from being heated to evaporation, but otoh outgassing the surface with heat might help to pull wd40 into any porosity when it's used as a quench
@liquidrockaquatics3900 9 місяців тому
That’s what I was thinking, whenever he was spraying on the WD-40. I figured it would be a lot more effective to spray the coating on and then heat it; you could then (basically) layer the polymer like when you season cast iron skillets

The beeswax flashes at 400f (205c), but not before the turpentine. Turpentine flash point is around 95f (35c). If you want to make this mixture homogenous, heat the beeswax to its melting point along with the linseed oil, which is slightly above the turpentine flash point. Blend those together at roughly 130f, remove from heat source and blend in the turpentine, which should be at room temperature. Only a small amount of turpentine will flash as this mixture will rapidly cool with the addition of turpentine. Turpentine is a volatile substance and will gradually evaporate at room temperature, and linseed oil hardens as it reacts with oxygen, so it isnt absolutely necessary to heat anything for this to be an excellent rust-proofer. The prepared mixture and metals simply being at room temperature works excellent, and double boiled linseed oil can be used if you'd like it to dry slightly faster, due to the drying catalysts added. If you're really impatient, you can use a heat gun to bring the temperature up to the flow point of the mixture and carefully maintain it near that temperature for a while, ensuring you are cautious of ignition. In short, don't blow your fucking oven up by putting turpentine in at 350f.

Be aware, that any high tensile bolt will be softened by heating it to blue temperature, you may then shear it if you try to tighten to a specified torque. For the best black, I use old diesel engine oil.

Fun video. Thanks. With bolts, I just remove them, clean them up, lubricate threads then reinsert followed by hand applying some nice combination primer / colour paint over the top of bolt to keep rust at bay (and for asthetics). I don’t like to take chances with bolts even if they’re not HT.

On C2 and C3 Corvettes, we have what is known as "the bird cage", which is, quite literally, a cage that surrounds the cockpit of the Corvette, and is the A-pillar and upper frame for the windshield. The birdcage is very susceptible to water intrusion when rubber seals are worn. And when this happens, the birdcage can rust out. Your brass coating technique looks like the perfect way to protect those vulnerable sections of the birdcage, including the bolts. Thank you!

if you have zink-coated steel screws, try dropping them in vinegar. the vinegar will dissolve the zink, and possibly create a black surface on the steel (depends on the underlying steel). hot coat in WD40 will also make an interesting surface finish. (we used the process for small #6 3/8 plastite screws (100s) and usually did a slow dry instead of a hot coat with the WD40, as it was easier to let the screws bake in the sun for a week))

Absolutely - I have been vinegar (acetic acid) dipping to remove fake chrome plating from bolts on my Triumph motorcycle. The vinegar strips off the fake chrome overnight and leaves a wonderful very dark surface. Don't know what some of the bolts are made of, can't pick them up with a magnet.

I set the parts on my wood stove and leave them for some time to make sure the heat is even. The pieces I have done are only decorative so I don't worry about the temper of the part. I have sprayed them with WD40 and used engine oil. I get a slightly different tone with each of them. I haven't tried linseed oil. Thanks for that idea.
@the_nondrive_side Місяць тому
the linseed oil has the bonus of being a polymerizing oil.. you can touch it up later with just a light application. I do that to bike frames after evaporust and convertor. tin foil cleaning for temporary shine is a thing too
@JK-photo77 9 місяців тому
This is the same as the idea of seasoning carbon steel or cast iron pans - it adds a polymer layer. Anything acidic or even a degreaser like many soaps, will remove it. It's not a 20-year fix but can last a good long time in situations. Smoke point of the oil matters, find that for each oil and you will find the optimum temperature. If you want black, try flaxseed or rice bran cooking oils. Grapeseed oil will give it a golden hue. The more coats the darker it gets.

I had to drill some hard steel. Too hard to drill, the drill did nothing. So here are the steps: Anneal it (soften it) first. Heat it to cherry red and let it cool 'very slowly' (the slower the better --- as much as an hour sitting in lime is good) Drill or work the metal to your hearts content Reharden it. Heat to bright red and quench in water or oil. The faster the better BUT: it will be hard but brittle and will break/shatter easily Temper it (it will stay hard but not brittle). Heat to 450 degrees (such as in a toaster oven) and let it cool very, very slowly ---- many hours. This will 're-align' the grains in the metal. Treat with oil/bluing for rust prevention. I use cold blue just like in the video --- the metal must be clean and it takes a few coats of bluing. It looks more 'black' than blue. Then wash off in water and treat with oil.
@78a67h 9 місяців тому
I thought the point of the exercise was to use an easier method to painting, whereas everything you show is much more involved. I would definitely leave the bolts alone not to mess up their factory heat treatment. A little oil of grease on the bolts would do the job.

Hi thanks for that enlightening video. The blacksmith I learned this thing from painted the objects with linseed-oil BEFORE heating them. The result can be heated down to a true black tone. I once did a complex object by putting the oiled object into our kitchen-oven which resulted in a not quite as black but nicely constant color. Actually I am looking for a simple (cheap yet effective and energy-efficient) way to do what you did with an awful lot of tins (to build a solar-air-heating-collector). I still can't see anything better than the oven-way. Lucky me, my wife is willing to get divorced anyway. ;)

@paulallen8597 7 місяців тому
the same temperatures he mentions in the video. I know this is for rust proofing without using paint, but when I work on engines at home, for parts that get really hot (exhaust manifold, engine head for example) I will use the oven to cure the high-temp paint as well. Note that you might end up with an odor from the fumes, so a fan and good ventilation is a must. With paint, the generally have some guidance on the can.

Another simple anti-rust treatment is Jenolite. It contains phosphoric acid which neutralizes rust, and there's a plastic in the solution which leaves a black or dark grey coating afterwards. It is a neat easy way of making rusty bolts look tidy, you don't even need to remove them from their location.

@pashakdescilly7517 9 місяців тому
@@CafeRacerGarage When I first met Jenolite, it was just one product, a purple jell with phosphoric acid. Now you can also get it as a liquid suitable for using as a bath to dissolve rust, as a red paste for smearing on rusty items. The Rust Remover leaves a matt black plastic coating. The Rust Converter leaves a thicker dark grey coating. I have used it in many ways - the spokes on the back wheel of the Vincent I am restoring had lost their plating and looked naff, so I smeared Rust Converter on them a couple of times, and now they look quite smart in a dark grey. For tidying up a tatty bicycle I prefer to put a smear of Rust Remover on rusty bolt heads etc, it looks dull black.

@BrunodeSouzaLino 9 місяців тому
The oil step of cold blue and hot blue is not optional. What selenium dioxide (which is what cold blue is) does to the metal is create a thin porous layer which needs to be filled with oil in order to create the protective surface. The problem with bluing metal using heat then quenching it is that you're putting it into a softer temper than what it had before rather than just applying a surface finish. For that, you have to apply the stuff BEFORE heating the metal.
