Abstract The present study shows the potential of high-resolution imaging and nano-Fourier-transform infrared (nano-FTIR) spectroscopy for corrosion science. The protective oxidation layers of different chlorine-gas treated silicon carbides (SiCs) were characterized with these techniques. A nitrified SiC showed the highest resistant strength against chlorine corrosion at 1000 °C compared to the other SiCs. Nano-FTIR spectroscopy with a lateral resolution below 40 nm detected differences in the crystallinity of the bulk-SiC and in the transitional region to the protective layer. Furthermore, high-resolution imaging provides deep insight in the interfacial layer between bulk-SiC and the protective oxidation layer on sub-micrometer scale.

纳米傅里叶变换红外纳米 FTIR 光谱分析不同碳化硅的空气和氯气腐蚀

摘要 本研究显示了高分辨率成像和纳米傅里叶变换红外 (nano-FTIR) 光谱在腐蚀科学中的潜力。用这些技术表征了不同氯气处理的碳化硅 (SiC) 的保护氧化层。与其他 SiC 相比，氮化 SiC 在 1000 °C 下表现出最高的耐氯腐蚀强度。横向分辨率低于 40 nm 的纳米 FTIR 光谱检测到体 SiC 的结晶度和到保护层的过渡区域的差异。此外，高分辨率成像可以深入了解体 SiC 和亚微米级保护氧化层之间的界面层。
