Sorry, that was a bit of a belligerent drunk post because I’m tired of threads about magnets.
To clarify what I mean by titanium. There’s Titanium Nitride (TiN) coatings which are sputtered onto the magnet and look like gold. They’re super thin, but they always fail alone because of microscopic pinholes.
There’s also been research done into using titanium alloy sheets (probably something like Ti-6Al-7Nb) which would be pressed into the shape of a magnet sized cavity, the magnet would be inserted, then another sheet would be laser welded over top to seal it. This is the expensive larger scale process I was referencing. While it may produce a significantly longer lasting magnet, we would have to do small batch prototype runs (manufacturers hate those) because we’re not sure what’s optimal. We’re talking hundreds of thousands of dollars.
Even if that did work, we may need to do more testing on some kind of passivation layer between the magnet and the titanium alloy shell to prevent unpredictable failure states like those caused by galvanic corrosion.
So suffice it to say that it’s complicated and extremely expensive with a distinct possibility of yieldless failure. Why do you think Amal hasn’t done it yet? There’s more valuable research the community could be spending it’s time on than fixating on the perfect magnet implant when we already have good enough options available. Please don’t tag Amal in this thread. He’s pretty burned out on the whole thing.
Also @ODaily I’m sure this wasn’t your intent, but I perceived some of what you said as really condescending toward Coma for no raisin. Food for thought
