本文是关于Fe - 9Cr - 1Mo马氏体钢（T91）在静态液态铅铋中氧化过程的一项全球性研究的第三部分。它着重于一种双层氧化皮的生长动力学模拟。氧化层由内部的铁 - 铬尖晶石层和外部的磁铁矿层组成。磁铁矿层的生长受铁在铁 - 铬尖晶石和磁铁矿晶格内的扩散所控制。进行了一种与实验动力学相匹配的解析模拟。还模拟了铁 - 铬尖晶石层的生长动力学。通过模拟以及使用辉光放电光谱仪（GD - OES）进行的一项独创实验确定了保护性氧化皮。（c）2008爱思唯尔有限公司。保留所有权利。
This paper is the third part of a global study on the oxidation process of a Fe-9Cr-1Mo martensitic steel (T91) in static liquid Pb-Bi. It focuses on the growth kinetics simulation of a duplex oxide scale. The oxide layer is composed of an internal Fe-Cr spinel layer and an external magnetite layer. The magnetite layer growth is controlled by iron diffusion inside the Fe-Cr spinel and the magnetite lattice. An analytical simulation, matching with the experimental kinetics, is performed. The Fe-Cr spinel layer growth kinetics is also simulated. The protective scale is determined by simulation and by an original experiment using GD-OES. (c) 2008 Elsevier Ltd. All rights reserved.
