中文摘要：

在超重力垂直于电极表面的情况下,研究超重力场对水溶液金属电沉积镍箔的组织结构和性能的影响,利用原子力显微镜（AFM）和X射线衍射仪（XRD）对沉积镍箔的表面形貌和晶体结构进行观察。结果表明：超重力场下的镍箔晶粒细化,表面更平整,当重力系数为354时,表面粗糙度由常重力下的20.9nm降低到4.9nm;并且随着重力系数的增加,沉积镍箔的晶体结构从有择优取向结构转变为无特定的择优取向结构。力学性能测试表明,当重力系数为354时,沉积镍箔的硬度和抗拉强度分别达到HV898和944MPa,比常重力下分别提高了HV604和646MPa。

英文摘要：

In a high gravity field vertical to electrode surface, the effects of high gravity on the microstructure and properties of Ni film deposited electrochemically were investigated. With atomic force microscopy （AFM） and X-Ray diffraction. The results reveal that the surface structure of nickel film deposited under high gravity condition was more uniform and smoother compared with that in normal gravity condition; under G = 354, the roughness decreased sharply from 20.9 nm to 4.9 nm, and crystal grains diminished with the increasing of gravity coefficient. Furthermore, its crystal structure transforms from tropism to non-tropism with gravity coefficient. The hardness and tensile stress of nickel film are raised markedly to HV898 and 944 MPa when the gravity coefficient was up to 354 g, higher than those in normal gravity condition by HV604 and 646 MPa, respectively.
