| 摘 要： | 低碳钢经浓硝酸浸蚀预处理后,调节氧乙炔火焰成碳化焰,预处理过的低碳钢基体表面火焰沉积获得纳米炭纤维涂层。采用扫描电镜、X射线衍射和显微激光拉曼光谱等先进分析手段对其形态和结构进行了表征。研究发现纳米炭纤维相互缠绕弯曲,石墨化程度高,直径为80nm~100nm、长度为4μm~5μm,形态短而粗。纳米炭纤维相互排列紧密但与基体结合力弱易从低碳钢表面脱落,浓硝酸浸蚀预处理的低碳钢表面在火焰中形成大量氧化铁颗粒,催化纳米炭纤维成核生长。

| Abstract: | Carbon nanofiber (CNF) coatings were successfully deposited on a low carbon steel substrate that was pretreated by concentrated nitric acid using an oxy-acetylene reducing flame. The morphologies and the microstructures of the CNF coatings were characterized using scanning electron microscopy, X-ray diffraction, and Raman spectroscopy.The CNFs were compact, entangled with each other, and highly graphitized with diameters from 80 to 100 nm and lengths from 3 to 5 μm. They tended peel off the substrate because of a weak adhesion strength. Iron oxide particles were produced on the pretreated low carbon steel substrate surface in the flame, and these acted as growth catalysts for the CNFs. |
