I remember hearing rumors years ago of a method (in the USSR) where
thin uniform diamond coatings were, fairly readily, coated onto most
anything relatively easily (i.e. knife edges, etc.) - Anyone know if
that's a reality or not? (Perhaps this is what's being used for the
coatings in lasers & the multi-chip modules, I hope? <G> Or is
something like diamond "roadway" embedded in epoxy resin or something
what's in use nowadays? I'm looking for diamond "plating", in effect.)
Friend & I are more kidding about making IC's as a specialty shop,
than in using diamonds for heat sinking (He knows enough about heat
transfer that I don't doubt him at all, I just mis-communicated. Mainly
I doubt our ability to do that type of thing, unless we both drop some
other plans in progress!)
Maybe some of that data's more available nowadays? (Not just usable
for heat sinking, one widget I want to make might work if it's pivot
bearing surfaces wouldn't wear out in a month or so...)
