Abstract
The oxidation kinetics of Armco–Fe in stagnant lead melts saturated with oxygen at 550 and 650 °C was investigated and the peculiarities of structure, phase and elemental composition of scales were determined. At 550 °C oxidation follows a parabolic law up to 1,500 h and then (1,500–2,000 h) oxidation accelerated. At 650 °C during 100 h the scale grew rapidly according to a quadratic time dependence. Then (100–500 h) the oxidation rate decreased sharply. From 500–1,000 h oxidation accelerated. The scales formed at 550 and 650 °C consisted of Fe3O4 and FeO/Fe3O4, respectively. The scales had a duplex structure. The outer-oxide layer grew from the initial solid metal–liquid metal interface towards the melt while the inner layer grew towards the iron substrate. The defectiveness of scale altered with time. The possible reaction mechanisms in the Fe–Pb[O] system are discussed.
