摘要: 采用电沉积方法,在含KMnO4的ZnSO4溶液中,通过控电位和控电流,得到高择优取向的(0002)和(101 1)Zn沉积层。用X射线衍射技术和扫描电子显微镜进行表征。结果表明这种高择优取向的Zn沉积层与相应的Zn单晶具有相似的XRD图,且具有比较完整的晶体结构,几乎不存在位错应力;还通过阴极极比曲线讨论了形成高择优取向Zn沉积层的可能原因。

Abstract: Zn deposits with(0002)and(1011)highly preferred orientation were obtained in the solution of 0.8 mol/L ZnSO4,0.5 mol/L H2SO4and 4.0×10-4mol/LKMnO4by controlling tlie deposition potential or current.The deposits with highly preferred orientation were studied by X-ray diffraction and scanning electron microscope.The results showed that tl1e diffraction patterns of the deposits with(0002)and(1011)highly preferred orientation were very similar to tlie corresponding patterns of Zn single crystals. But there were little disloction stresses in the deposits.The effort was made to explain the reason for the deposits with highly preferred orientation from the polarization curve of the solution.
