Wetting oxidized Fe, Ni, Co alloy with copper

Beavis, L.C.; Roherty-Osmun, E.; Ritchey, M.B.

Experiments were run to determine if oxidized Kovar could be chemically cleaned so that copper would wet the Kovar in a wet hydrogen atmosphere at 1100{degrees}C. We found that a multi-stepped acid etch process cleaned the Kovar so that copper would wet it. We also found that the degree of copper cracking after melting and cool-down correlated well with the degree of wetting.
