Subject: [Leica] The titanium Leica

This business about the titanium M6 has always bothered me. I'm no
expert but the concept of plating (electroplating) titaniunm on to
another metal (alloy) always struck me as not being possible. With that
in mind, I contacted a friend of mine, a PhD metallurgist. He wrote
the following, and I quote,

"My guess is that it isn't electroplated, but it certainly can be
deposited via PVD (Physical vapor deposition). Those golden drill
bits you see at Sears are titanium nitride coated. Run the same
process in a vacuum instead of nitrogen and you get plain
old titanium on the substrate."

There's gotta be somebody out there who has the idea of exactly what
Leica did. I wonder if they cast the M6 titanium? But, that means it
would have had to be cast in a vacuum. If you melt titanium in air, it
will catch fire.

So, who knows?

Regards

Kurt
