Supermagnetman TiN Batch
I just bought a pack of 10 TiN coated magnets (https://supermagnetman.com/collections/neo-discs/products/d1005b-10-tin?variant=12239757279348). After doing my best to clean off the ring of soot that each one had one one side of it, I put them in 5:1 saline solution. After 1 day, 5/10 of them have each formed a tiny bubble in their coatings, but still have magnetism. I plan on leaving them in the solution for around 2 weeks and then examining them under a microscope for any holes that I couldn't see with my naked eye. So far, the results are as I had expected based on the other posts concerning the TiN magnets that SMM sells. (They advertise their parylene magnets as bio-compatible, but explicitly say that their TiN ones are not FDA approved for in-body use). I will continue to update this thread with the results of the remaining 5 magnets as I continue to test them.
