Is there a diy guide to home magnet coating?
I've looked everywhere and at most I've seen people discuss different manufacturers and different coating materials.
I've seen that some people on here do small batches and allow people to go in on them once they are made aware of the risk of failure and infection, but, I've never seen a guide, or any documentation at all really, on the matter of making them.
I know that some of the processes involve a multi-part molding/casting process. Others are out of the question because they require cost prohibitive equipment. I'm not looking for anything definitive, just general points of reference or documentation of tried processes or research.
I'm asking because I bought several of those small gold coated high strength magnets from gaussboys a while back and have been puzzling out how to go about experimenting with coatings. I of course wouldn't implant anything I haven't done extensive testing on first, but I have equipment to test anything if I just knew how to go about experimentally coating them.
I have a home lab that has several magnets, chemicals, metal/plastic/glass tools and equipment including test tubes and beakers, microscope and camera equipment, 3D printer, mold release spray, smooth-on 2 part silicone for molding and casting, and a whole electrical station with reflow station and variable power supply.
I'm in a good position to buy materials within a certain budget as well.
If you have made home coated magnets, or know of a guide or documentation on the matter I'd be super thankful if you could link them below and discuss them.
thanks! <3

Oh cool! Man, you're always on top of things here!
So stuff I've been working on include testing for moisture/vapor absorption. This can be done by filling curing a resin, and then weighing it. Then you soak it for 72 hours and weigh it again. This give a good approx of how much fluid it picks up. There are also ways to test the strength of the coating. And of course we need tests to see if the coating is cracked or flawed. I was doing a kind of nickel to dimethglyoxime soak but I'm not sure how good this really works and tenders the magnet unfit for implantation. I've been working with this guy who's got a ton of great ideas and he may have a method using capacitance that would be better. We haven't actually tried it yet but I'm excited.
I'd be interested in what equipment is used for the mechanical testing and what metrics are of interest. I imagine pressure and chemical tests are involved to determine coating effectiveness, but how are they being done? With some sort of press? With saline or stronger chemicals? I've seen a bit from browsing people saying they are testing coatings.
@radon u know you can take it to the dms w cassox right?
I'm from Utah. Sorry about posting multiple comments in a row like that, I wasn't really thinking about it. I can see how it'd be annoying to see this thread look like it's more active than it is with unnecessary posts. I'll DM you my slack in a minute, I don't use it as much, but I have notifications set up and i'm pretty quick to reply, so it should be effective means of communication.
