Multilayer bi-metal foil of copper and titanium


#1

Dear Orchidians,

We use a 3 inch mirror to monitor an electron beam on target metal
during evaporation (physical vapor deposition). The mirror gets
enough metal on it that it periodically needs to be replaced or
cleaned. Today the metal began to peel, making it difficult to see
the target.

The metal that peeled off is now a foil of
Cu/Ti/Cu/Ti/Cu/Ti/Cu/Ti/Cu/Ti/Cu. The copper film thickness is
typically 2500A to 3000A (Angstroms) and the titanium is 300A for
each layer. Each Ti/Cu layer was added on different days, but under a
vacuum that was not broken until today. The target metals start at
99.9% purity, and through control of the process any remaining
impurities are either evaporated on the shutter or left in the
target. So it’s a very clean, shiny, pure metal foil.

Is anyone interested in trying to use it to make jewelry? I only
have one foil. It’s free. Please email me off list to <@Jeff_Simkins>.

If you get any takers, I think it should be on the condition that
they must provide pictures to the group when it is finished!

don’t know about this, but Rex Steele Merten, who sometimes posts on
this list has been working with a beautiful mixture of twisted gold
and titanium - just stunning! ( are you listening Rex? )
