Migration of ions on oxygen-deficient chromium oxide electrodeposited from trivalent chromium electrolyte
Source abstract
Abstract
The migration of cations on electrodeposited chromium surfaces, with and without a polymer coating, is studied by in situ scanning Kelvin probe measurements in an inert atmosphere. The reactivity of the chromium-based coating to the ambient atmosphere is studied using in operando ambient pressure X-ray photoelectron spectroscopy in different atmospheres and is shown to have significant impact on cation migration. These findings provide novel and deep insights into ionic mobility at surfaces and along interfaces. Furthermore, an improvement to the conventional cathodic delamination mechanism is proposed based on the outcomes of this study.
