High-temperature iron oxidation within the oxidative development approach

Resumo

High temperature iron oxidation within the oxidative development approach was carried out. It was found that, in the temperature range of 750–850°C, the kinetics of the iron oxidation with the use of the oxidative development approach was described by a parabolic law. The formed compact oxide ceramic has a uniform thickness which reaches 7 mm at 850°C within 14 days. It was found that, with the increase in volume of the initial metallic sample, the rate of the high temperature iron oxidation decreased. The ceramic obtained within 14 days at 850°C was characterized by a laminated structure.
