Hello
What are the conditions under which 100% reliable contact between two metals
is guaranteed? My hypothesis is that there are only two possibilities:
1) gold-to-gold
2) The touch point is under permanent great preload which causes the crystal
lattices to deform plastically and be fused together (like in wire nuts -
you can see the denting on the wire)
The contact is supposed to be generally subject to high-amplitude thermal
cycles (-30 to +70 degC) for years with very difficult maintenance. It
won't be subject to condensing humidity or direct weather exposure. And
must be repeatedly disassemblable without soldering.
