| 采用电沉积方法在冷轧过的黄铜片表面制备了纯铁薄膜,并通过改变电极的排列方式来探究纯铁薄膜的生长关系。 利用 X 射线衍射仪对纯铁薄膜进行宏观织构的检测;利用热场发射扫描电子显微镜(FE-SEM)观察电沉积纯铁薄膜的岛状生长结构;利用扫描电镜自带的 Oxford Nordlys Nano 软件对纯铁薄膜的取向进行分析。 结果表明:当电极采用平行排列方式时,晶粒呈现由小长到大的趋势,且有明显的择优取向,生长速率缓慢,呈抛物线模式生长;当电极采用垂直排列方式时,晶粒大小基本不随时间变化,没有明显的择优取向,但生长速率较快,也呈抛物线模式生长。 |

| Abstract: |
| Pure iron films were prepared on the surface of cold-rolled brass sheets by electrodeposition and the growth behavior of the films was investigated by varying the arrangement of the electrodes. The macroscopic structure of pure iron films was exam- ined by X-ray diffractometry and the growth behavior was revealed by thermal field emission scanning electron microscopy (FE- SEM). The orientation of the pure iron films was analysed by the Oxford Nordlys Nano software to analyse. Results show that an island growth structure on the pure iron films is deposited by electrodeposition. After the parallell-arranged electrode is applied, the grains grow at a very slow rate with an obvious growth orientation and the grow rate has a parabolic pattern. When the elec- trodes are arranged vertically, the grain size does not change much with time without obvious growth orientation. whereas the grow rate is quite bigger, behaving a parabolic pattern as well. |
