Feel free, Brimstormer.
I don't believe the assembly was coated in anyway. One person familiar with the equipment's history did mention a slimy film had been discovered on the interior, so, yea, it figures.
If any clear resolution comes of this, I'll update the thread. Have a fine weekend...
Thanks true blood. I could suggest trying to confirm as much, since the new assembly is on order, we can trash the screws/washers and run som icp on them.
I would hope that replacing these every 6 months was in the preventative maintenance schedule, will check.
Thanks again.
A few other observations I'd have made were it not for my passing infatuatuion with linking images...
I am not sure of the composition of the screws, or the washers [possibly of the locking variety] used. All of them look pretty cruddy.
The rod shown in the first image, which I thought was...
[apologies up front, it appears the photo link coding is not cooperating. For those bold enough to try the links, please repost them if both time and interest allow.]
This happens to be 4140 low alloy steel. The part imaged serves as the plug at the base of an isostatic press. The sealing...
Trueblood, thanks for that document, very interesting.
In the magnetics business, the condition of thin walls, such as pipelines, are measured by flux leakage. I wonder how/whether the methods overlap.
Is this based in the United States? If so, how is the NRC not all over your project?
We used a beta source to track glass level/flow, and the spare was kept in a safe that would trigger an alarm at an NRC office. That's beta, electron radiation, no big deal.
The hoops to jump through to use...
It turns out we can't do a thing with regard to MnCu. You might reach out to Ilpea and Hoosier, both ferrite manufacturers.
As for fitting a magnet into your system, could a small electromagnet work into the design?
Also, to clarify, I presume you realize that hitting the curie temp is a...
yes, they are pushed higher for motor applications. You want something to become demagnetized at 50°C[~122°F], to achieve...?
What are you hoping to study?
I should hear back whether the aforementioned branch has ever dealt in mncu ferrites. Failing that, I know of two alternatives that...
A branch of the company I work for does manufacture ferrites, and they may be able to batch a small amount of the composition you're interested in.
That said, any magnetics you could get out of what you've determined to be obsolete magnets can be provided, and with better uniformity, by newer...
"Why?" seems to be a very reasonable question.
are you hoping to exploit the curie temp, specifically? I'm certain they can still be produced, and may still be produced, I can find out more in a day or so.
What are you trying to accomplish with these magnets?
I ask because other magnets...
Vermonster, would it help if you provided us with the first patent? I mean, it's already protected by patent, and the details therein may help us help you.
Re: time; believe it or not, we all are saying the same thing, but focus specifically on the last sentence in paragraph two of Magben's...

Any metal that would become magnetized would not become more so over time once it is saturated. This is part of the reason there are permanent magnets. Metals that can maintain some magnetism, such as steel, slowly "bleed off" that magnetism.
Critical: the metal you select must either...
