Laser Raman spectroscopy is one of the most suitable methods for"in situ"observation of the oxidization process of metals from the following points of view ; specimens are not destroyed and a small area can be analyzed by micro-Raman spectroscopy. We developed the "in situ"measuring system, which has a triple monochromator, a CCD detector, and a heating stage which can change the environmental conditions, for an oxidization process of metals by using Raman spectroscopy. This system clarified that the growth process of oxide films during thermal oxidization of Fe-6.5mass%Si alloy at 1073K in O_2 and CO_2 atmospheres depends on the concentration of the oxygen defects in the SiO_2 surface layr. This system also performed to observe the oxidization of the liquid Al and Al-Mg alloys at 1273K.This system developed in this study is the suitable method for"in situ"observation of oxidization especially at high temperatures.

激光拉曼光谱是最适合“现场”观察金属氧化过程的方法之一，从以下几个方面来看：样品不会被破坏，并且可以用微拉曼光谱分析小区域。我们开发了“原位”测量系统，该系统具有三重单色仪，CCD探测器和可以改变环境条件的加热阶段，用于利用拉曼光谱测量金属的氧化过程。该体系阐明了fe -6.5质量%Si合金在O_2和CO_2气氛下，在1073K温度下热氧化氧化时氧化膜的生长过程取决于SiO_2表层氧缺陷的浓度。该系统还对液态Al和Al- mg合金在1273K下的氧化进行了观察。本研究开发的系统是“现场”观察氧化的合适方法，特别是在高温下。
