Fama2电解抛光对低碳钢EBSD制备的影响

摘要

Electron backscattered diffraction technique is a strong beneficial tool for micro area orientation analysis, but it re-quires strictly for sample surface state. By the electrolytic polishing method, this research focuses on removing surface roughness and deformation of denudation, changing the electrolytic polishing voltage and time, and observing morphology and determination of roughness so as to make a research of the electrolytic polishing process on the influence of sample surface morphology based on low carbon steel plate for test material. The optimal voltage is 12V, and the optimal polishing time is 40s in the preparation process. The Surface is flat and the roughness is small.%　　电子背散射衍射技术是微区取向分析的强有利工具,它对试样表面状态要求严格。我们以低碳钢板为试验材料,通过电解抛光的方法对表面粗糙和变形层进行剥蚀,改变电解抛光的电压和时间,观察形貌和测定粗糙度,研究电解抛光工艺对样品表面形貌的影响。最终确定最佳的制备工艺为：电压12V,抛光时间40 S,达到表面平整,粗糙度小。
