Electrochemical Estimation of Developed Roughness of Galvanic Nickel Coatings

Protection of Metals Aims and scope Submit manuscript

Abstract

The roughness of nickel coatings with highly developed surface (constituted from dendrites) can be estimated by measuring their differential capacitance under cathodic polarization in weakly acid sulfate solution. For the same purpose, using diffusion- or kinetics-controlled electrochemical reactions yields underestimates.
