Модельний підхід у створенні поліфункціональних електродних матеріалів

Abstract

A model approach for the creation of polytifunctional electrode materials has been proposed. Based on the data of computer modeling of long-term growth of cathode deposits in the Comsol Multiphysics and polarization measurements, the selection of surface-active additives of sulfate nickel plating solution has been substantiated. Addition of 0.2 g/l of saccharin into the nickel plating solution in order to increase the throwing power and obtaining of bright fine-crystalline unstressed nickel deposits has been proposed. Based on studies of the morphology of cathodic nickel deposits obtained on a rotating cylindrical electrode at current density 10 – 15 A/dm2 and retation speed 150 rpm, the pH value of 4.4 - 4.6 of the nickel plating solution has been substantiated to obtain high-quality thick-layer Nickel coatings without pitting and shells.
