研究了表面处理对Super 304 H在水蒸气和超临界水中结垢行为的影响。使用具有能量色散X射线检测器的扫描电子显微镜、X射线衍射和拉曼光谱分析氧化皮。结果表明，表面变形促进了氧化铬的择优生成，提高了氧化膜的附着力，从而提高了抗氧化性能。在SCW中，赤铁矿的情况下，可能归因于低氧分压，而喷砂样品上的晶须生长可能是由于低氧分压和增加的铬扩散通量。
The effect of surface finish on the scaling behavior of Super 304H was investigated in steam and supercritical water (SCW). The oxide scales were analyzed using scanning electron microscope with an energy dispersive X-ray detector, X-ray diffraction, and Raman spectroscopy. The results showed that surface deformation improved the oxidation resistance by promoting the preferable formation of chromia and improving the scale adhesion. In SCW, the absence of hematite may be ascribed to the low oxygen partial pressure; while the whisker growth on the sandblasted sample may have resulted from the low oxygen partial pressure and the increased chromium diffusion flux.
