How Do I Blacken Niobium?
I am looking to create a bio-compatible black finish (matt or polished) to small niobium parts (jewelry). I have heard this is done by heating with a torch then following a particular cooling process.
Maelstrom Studio Lab, Inc. - DeLand, Florida, USA
- 1) what types of gases are recommended
- 2) details of the cooling process
- 3) am I completely lost?!?
