研究了铌在硫酸-甲磺酸体系中的电化学抛光。通过SEM/EDX和XPS方法研究了NbOx/Nb表面，以找出氧诱导结构的化学组成。具体地，在EP处理之后获得的XPS结果表明在样品表面上氧与铌氧化物占优势部分。为了正确解释这些结构，分析了主要铌氧化物的光电子能谱，测量了它们的内部Nb 3d和O 1 s电子态谱和价带谱。(C)2012年爱思唯尔B。V.保留所有权利。
The studies of niobium after electrochemical polishing EP in sulfuric-methanesulfonic acid mixture were performed. The NbOx/Nb surface was studied by SEM/EDX and XPS methods to find out the chemical composition of the oxygen-induced structures. Specifically the XPS results obtained after EP treatment indicate prevailing part of oxygen with niobium oxides on the sample surface. In order to correctly interpret these structures the photoelectron spectra of main niobium oxides were analyzed, and the spectra of internal Nb 3d and O 1s electronic states and valence band spectra were measured for them.
