Making new m31 to fill the shortage
edited March 2016 in Magnets
To fill the shortage of M31s I ordered some magnets that are nickel coated 3 mm x 1 mm Disk magnets and have talked to a company that does medical grade titanium nitride coatings. I am going to have two magnets coated as a test to see if this is a viable option. Does anyone see why this would not work? Or any reason why this would not be safe to implant?
Think about it like a shadow, the coating can't reach the other side and that is why he plans to flip it over. How much worse is nickel than neodymium? I don't know, but I would not want to find out. Things we say like that comes from experience and multiple points of views. Hence why I prefer something I can verify on this bored vs something I read off of google.
Nickel sucks but if you had an adequate tin i wouldnt worry about it. If you go ahead let me know. Ill send you some of the nickel exposure solution i use.
Not to familiar with the bio compatible plating solutions, but should be one that can be used like this?
As mentioned before, doing the TiN coating on either a bare or tin-coated surface would make for a very bad worst-case scenario should the coating fail. However, I do have a thought or two, aswell as a question (bottom) here:
Would it be possible to perhaps use a very thin layer of gold plating sandwiched between two layers of TiN, or would that perhaps have too many negative consequences with regards to the mechanical and magnetic properties?
If this could be done it would not only give you a comparatively safe, protective boundary layer should the top coating fail, but also include a "fail-safe" (now free from leaks to an acceptable degree of certainty, right?) bottom layer underneath that should be, theoretically, very durable?
And even if this bottom TiN coating should include some pinholes, these would likely be made quite leakproof by the gold on top, somewhat like the tar coat applied onto wooden ship hulls?
This three layered approach would also have the added benefit of (and please correct me if I'm dead wrong here) making it possible to (accurately) inspect at least the top TiN layer for pinholes etc using a small Tesla coil? I'm fairly certain this should be possible, in theory at least, given:
The top coating isn't too thick. (check?)
Enough difference in the electrical conductivity of the two materials (check?) Where the sub-layer should preferrably conduct more readily (check?)
