Oxidation behavior of Kovar alloy in controlled atmosphere

Dec 01, 2008 · But considering the pressure of potential oxides of Kovar alloy limitation of diffusion velocity, the migration and temperature. rate of Fe in the Kovar is much higher than that of Ni and Co[9] . As a consequence, all kinds of oxides formed at the outer surface of Kovar are immediately covered by Fe oxides with the increase of oxidation time.
