Analysis of coatings

Quick question - does anyone here have access to proper lab equipment (specifically an electron microscope would be handy) for the purposes of analysing a removed implant's coating?

I'm pondering trialling some coating materials by leaving them in for a month and then cutting out and inspecting them.

    I think @cassox has done something similar i beleave

    I have electron microscope access now but 2 things. 1, under that kind of magnification, everything looks bumby as fuck. About 200-400x is more than enough for our purposes. And a half decent microscope can do that. Hell you can get one on ebay for 50 bucks that'd do that. 2 each session is a couple hundred bucks so it's not a wander in and use it kind of deal, least at my school. Since to use it, it needs a metal coating (gold) which they have to apply to every sample, and it's slow to use and you only get an hour.

    for leakage detection, couldn't you put in some fluorescent liquid, evacuate the air, and afterwards inspect under UV light?.
    Alternatively you could build a leakage detection test circuit. With a few FET's you can detect even the tiniest currents. Given you test it in some sort of conductive liquid (everyone has some salt at home, right?)
