Q. Our parts, made of 99.5% alumina, have carbon deposits that show up after our brazing process. We do not use a flux for our ceramic parts; we high-temp fire a moly/manganese painted paste onto the ceramic. The part is then sent out for nickel plating to prevent corrosion of the moly manganese metallization areas. The next step is our brazing.

We are not seeing any spots on the parts before brazing, but as we continue through 5 brazing cycles and braze in a hydrogen/Nitrogen furnace with the cusil braze rings, we see black spots forming that show up as high-carbon deposits with the SEM data…
