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.

@@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.

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.

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.

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.

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.

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 Жыл бұрын
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 Жыл бұрын
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
