I am researching the process for blackening tantalum and am finding
it almost impossible. I am wondering if the process is similar to
colouring of titanium and therefore the results are the same i.e
surface oxidisation only, or if there is a process that yields a
hard wearing surface colour that will need minimal maintenance for
strength of colour. The tantalum portion of the design will be
taking all the ‘hard knocks’ and as the design is a wedding ring it
will obviously be worn everyday (or should be ;0).
Also any tips on fusing/welding would be helpful also…
Can anybody help me? Any would be greatly appreciated.
