Fe-Al和Fe-Cr-Al合金的初始氧化：Cr作为氧化铝促进剂
Initial oxidation of Fe-Al and Fe-Cr-Al alloys: Cr as an alumina booster
摘要：
用X射线光电子能谱学研究了Cr对Fe-Al合金表面氧化铝保护膜生长的促进作用。使用低氧压，从氧化的第一时刻开始监测合金的表面化学。通过分析原子浓度模型中测得的表面浓度，可以清楚地检测到铬对Fe-Al表面-体交换的影响。以前的从头计算与目前的实验符合得很好。
英文摘要：
The boosting effect of Cr on the growth of the protective alumina scale on Fe-Al alloys is investigated by x-ray photoelectron spectroscopy. Using low oxygen pressure the surface chemistry of the alloys is monitored starting from the first moments of oxidation. Chromium effect on the Fe-Al surface-bulk exchange is clearly detected by analyzing the measured surface concentrations within the atomic concentration models. Previous ab initio calculations agree well with the present experiments.
