Fusing High Karat Gold to Niobium? (i.e. Keum-Boo)


#1

I’m familier with working in Niobium and I have done Keum-Boo before. I would love to mix these two metals.
I fully understand why you can’t solder niobium, I’m wondering if anyone has had any success with fusing it at all?

Hi Rivka,
I believe you’d have to do this in a vacuum in order to make it stick. The natural oxide layer will prevent anything from sticking if you aren’t in an inert atmosphere.

Does the sparkiee acomplish this because it blasts the air out for a split second?


#4

Is there the possibility of setting up a vaccum work box? Like how we reach into a sand blasting box after sealing out piece in?

Clearly it would be crazy complicated


#5

That is exactly what the Sparkie II does!


#6

I don’t know if there’s a DIY way to do that…If there is, someone on the forum will definitely chime in =)
I know the laser welders use an argon gas shield to weld in as it accomplishes the same result.


#7

I can fuse gold findings onto Niobium sheet with a Sparkie, correct?


#8

Only fusion findings–they have a small fusion nib on them. The Sparkie will not fuse together 2 random pieces of material. You can see some examples here:https://www.reactivemetals.com/sparkie-ii-fusion-findings


#9

Oh yeah, im familiar with how and why they work, just asking if a gold fusion finding to Niobium base worked?


#10

Yes, the Sparkie will fuse dissimilar metals so if you had a gold fusion finding, you could fuse to Nb no problem!
