Tyson I’ve said it before and will say it again your videos are always very clear and to the point. You’re a natural. Thank you for bringing us these videos. Much love and gratitude

@MakeItWithCalvin Год назад

Ditto! No over the top hype, just straight facts.

@noahc6544 Год назад

One thing you could look into for the new tank is a literal thermal fuse, since you'll have a lot of water in there it shouldn't need a super high temperature rating

@jamiemacdonald436 3 месяца назад

Tyson makes the best videos on this channel. Clear and concise. And he doesn't make me feel as though I'm getting sold something for a change. Nicely done.

@ryanclarke2161 Год назад

Great vid Tyson, you've got a lovely voice for this sort or work and a great pace and way of explaining things.

@AeroenginnerJosh Год назад

A more simplified way of stating what passivation does, is the removal if the ferrous layer of material for the components surface. Often preformed on materials with a high chrome-nickle alloy, once the iron is removed the chrome and nickel is left exposed which has greater corrosion resistance. It is also important to note that for most large OEMs you will require outside accreditation from both the OEM and an external verifiers such as NADCAP.

@465maltbie Год назад

You dont talk about testing procedures to prove the passivation? If you do another video about the paperwork please include that also. Thanks for bringing this up. Charles

@danl.4743 Год назад

Did you read what it said on the document he showed? No need for verification.

@anthonyfrey9707 Год назад

@@danl.4743 Have you ever done work for the military. Just because a product states in their literature that it meets a particular standard does not mean that it's acceptable. In the standard, there is also a test requirement or multiple requirements that must be met in order to prove that the standard has been met. It is your job as the supplier to your customer to able to verify that the standard has been met.

come on.. we want to see the Swiss machine turn out a shiny stainless passifier for the big baby in the lab coat.. Way to go Tyson, its been a while since I saw one of your videos..

@RPrice_OG Год назад

Passivation isn't just for aerospace. If you are a home brewer or even a professional brewer then you may want to passivate all your pretty stainless stuff. I did this a couple years ago and it was extraordinarily hard to find someone to sell and ship the acid to me. I hope that this product will be available to hobbyists at some point.

@AwestrikeFearofGods 9 месяцев назад

Nice demo. Do you water-rinse in between the cleaner and the acid? I didn't see that step.

@mlt3258 Год назад

Nice!

@MattOGormanSmith Год назад

There are OTS kitchen devices with stainless tanks and redundant boil-dry protection. Maybe a rice cooker or a kettle would be a good size for you (not talking to the Titans here, unless they go to an industrial kitchen shop). Some of them will have suitable thermostats for that 120-160F range too.

@NinjaPooop Год назад

Great video! Is heating the solution a requirement? Let’s say I don’t have a heater, could I just leave it overnight?

@mjodr Год назад

Even though citric acid seems safe because everyone loves to use cute photos of oranges and downplay it like "hey, what could go wrong?", concentrated "industrial grade" citric acid products like this and Citrol are SERIOUS stuff. They are one of the best solvents I could possibly find in weeks of research. They aren't exactly splash it around and get it in your eyes and mouth kind of stuff.

@Berkana 22 дня назад

Would a sous vide machine work for that water heating step?

@protector7886 2 месяца назад

Does nitric acid work better to passivate stainless steel vs citric acid?

@peterCheater Год назад

Did you ever get NADCAP for the outside processing you took in housw?

@mrbimsky Год назад

Im not pro, but can i use baking powder + water for passivation?

@runcycleskixc 3 месяца назад

It would be nice to show what the passivation did to the steel part, apart from looking shiny. E.g. resistance to a salty solution overnight at high temps etc.

@VenturiLife Год назад

That ending though.. haha

@klasjanzen1165 Год назад

Waiting for the electro plating Since Barry did the anodizing, I was like: oh, I wish he did electro plating on carbon steel

@barrysetzer Год назад

We are all over it Klas! Stay tuned

@clutchboi4038 Год назад

Thank you for this! I weld stainless steel pipes for water filtration systems and have been wanting to build my own passivation tank. But since you are going into stuff besides exclusively CNC machining, I was wondering if y'all have thought about doing plate bending with a cnc press brake? I just got one for my business and am still learning how to set it up.

@eeeeweeezeee Год назад

Props to Tyson for not using the break room microwave for the science demonstration like I would have.

@barrysetzer Год назад

Beahahaha that reminds me of one time we almost boiled a part in methylene chloride in a crock pot in our office (pre-Titans). And then i read the MSDS and realized we would all die lol

Can you do a video on dimensionally stable anodising of aluminium?

@hamzanawaz7945 Год назад

@Vankel83 Год назад

Did you dump the Citric Acid down the drain? Or di you put in a holding drum like bad coolant to be picked up and dispose of properly.

@danl.4743 Год назад

No. He added sugar to it and he keeps it in the fridge for hot days.

@jameslmorehead Год назад

How about passivization with phosphoric acid such as Ospho? I use Ospho all the time for any iron item that is bare iron.

@NoctisIgnem Год назад

That only works for bare iron, stainless needs stronger acid

@myszkoscielna7522 Год назад

Great video, Tyson!

@Azalea__Rose Год назад

Does passivation alter the final dimension at all? like a coating might for example

@sbeprecisionproducts6729 Год назад

No it isn't adding or removing any material.

@billmcleangunsmith Год назад

You were using 17-4, but does it also improve corrosion resistance on 300 series stainless?

@mjodr Год назад

You can do this on lots of materials. I've actually done it on aluminum before using a slightly different process. I'm not doing aerospace certified stuff mind you.

@NoctisIgnem Год назад

I do this professionally, we use nitric acid on stainless.

@thelastgs-pian9965 2 месяца назад

isnt stainless steel rust proof so why passivate , will this work on mild steel?

@jenspetersen5865 Год назад

Why not just use a Sous Vide stick for heating and you get circulation at the same time

@AlessioSangalli Год назад

Hello, would this be useful after TIG welding?

@dragerx001 Год назад

tig welding put an oxide layer over welded joint and will cause it rust over time if not passivated.

@AlessioSangalli Год назад

@@dragerx001 so it's a yes?

Citric acid is used for skin peels so I would at LEAST wear gloves and rinse off well after this. Save your skin some surface burns!

@satchelsieniewicz5824 Год назад

its not a induction heater its a immersion heater. dont mean to be annoying all the best

@cdrom1070 Год назад

lol be careful with those heaters. You know what they do, I had one that started bubbling because of corrosion. So what happens if they get a breach in the vessel, then you have water enter the inside, turn into steam, and cause a steam explosion. 1ml of water expands to like 4 liters of steam IIRC. I have seen pictures of aquariums that looked like they had a fire cracker inside of them. I suggest you use a hot plate and a glass non chinese lab beaker... any chemicals mildly corrosive are no bueno for that POS aquarium heater. Glass beakers are super nice so long you are gentle.

@cdrom1070 Год назад

and I dunno if that is the same type of heater but you should be aware of the thermal mass of the heater. Basically its the same as a motor in a blower tube, if you turn it off abruptly and turn off airflow and measure the temp it will go up because there is latent heat inside of the thing that comes out, so normally stuff runs air for a while after it turns the motor off so it can cool down right. Those heaters will over-heat if you remove em from the bath abruptly and thermally stress them. The procedure is to turn it off and leave it in the bath for like a while. They suck.

@cdrom1070 Год назад

you might think the 160 temp is low so there is no risk, but the watt density of the heater is heavy, meaning that the actual inside of the heater is pretty damn hot given the small surface area of the thing. I am telling you get a hot plate and beaker b4 that bull shit goes off on u
