Abstract: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.
