Study of the Effect of Electroplated Nanocrystalline Nickel Grain Size on Corrosion Resistance, M.Sc. Thesis Sharif University of Technology ; Baghalha, Morteza (Supervisor) ; Kazemeini, Mohammad (Supervisor)
Abstract
In this project, nonocrystalline nickel coatings with grain sizes within the range of 9-27 nanometers were produced on yellow-brass plates by electroplating in a modified Watts bath applying current densities from 2 to 6 A/dm2 and bath stirring speeds from 0 to 400 rpm. To determine crystallite size, X-ray diffraction technique (XRD) was utilized; it was observed that grain size declined continuously with increase in current density and then in bath stirring speed. The experimental results coming from XRD tests were compared with a theoretical model in order to verify their reliability; the obtained curve indicated a good correspondence between the experimental data and the theoretical...
