Abstract
Pulsed electrodeposition modes allowed to obtain amorphous Co-W alloys. Using X-ray phase and spectral analysis methods, it was established that the deposition modes and the concentration of the amorphizing component (sodium tungstate salts) in an aqueous electrolyte solution affect the amorphization of alloys. The short-range atomic order was studied by X-ray diffraction analysis and the sizes of the regions of ordered arrangement of atoms were determined in X-ray amorphous Co-W alloys obtained by pulsed electrodeposition. The radial distribution function of atoms was analysed. The assumption is made that cobalt and tungsten atoms combine into configurations that are irregular polyhedrons.
脉冲电沉积模式可获得非晶态 Co-W 合金。利用 X 射线相和光谱分析方法,确定了沉积模式和电解质水溶液中的非晶化成分(钨酸钠盐)浓度会影响合金的非晶化。通过 X 射线衍射分析研究了短程原子有序性,并确定了脉冲电沉积获得的 X 射线非晶 Co-W 合金中原子有序排列区域的大小。分析了原子的径向分布函数。假设钴原子和钨原子结合成不规则多面体构型。
