inconel is Inconel 600 (72-14-8 Ni-Cr-Fe or something close to that) and the ceramic is titanium oxide, lead oxide, and zirconium oxide, if that helps. currently we using an argon environment for the brazing.
we have been putting a small piece of the In-Sn solder between the inconel and ceramic, wrapping it in copper wire, then putting it in the tube furnace. do you think think this method is effective? should we apply the solder to the inconel first, then put on the ceramic, then put it in the furnace to facilitate diffusion? my professor is leaving it up to me to find a solution, but i really dont have any experience with soldering.
thank you very much!
