Re-magnetize after coating?
Is there a reason re-magnetizing a magnet after coating has not been considered? I know one of the main issues with TiN and similar coatings is that the coating process requires heat and that degrades the magnetic force. Neodymium magnets can be re-magnetized with another powerful magnet. Its my understanding that this requires a high powered industrial strength electromagnet and would not be practical on a DIY or home scale, but surely we could convince a magnet manufacturer to re-magnetize some coated magnets for us.

Anyhow, yeah I've had stuff re-magnetized a few times. If you're already working with a company sometimes you can get them to throw it in for free for you. Adam Magnetics charged me something like 250 or so for a huge batch; however, the remagnetization isn't really the problem with TiN coatings. If you wanted to do something like Teflon or something that requires high heat, then you could do this and then remag.. but TiN just seems to have a high number of failed coatings. I'm not saying this can't be remedied. I'm just acknowledging that I've never found a way to do it. It's a shame too because the ultra thin coating performs so much better.
