TLDR
In this article, a two-step mechanism for the formation of hydroxyl ions (OH−) at the cathodic substrate by reduction of and dissolved, and then reaction of the hyroxyl ion with zirconyl ions present in the solution to form the hydroxide, which in turn decomposes on drying to yield Zirconia.Abstract:
coatings were deposited on graphite and titanium from an aqueous solution based on a water‐soluble precursor. A two‐step mechanism is suggested for the formation: generation of hydroxyl ions (OH−) at the cathodic substrate by reduction of and dissolved , and then reaction of the hydroxyl ions with zirconyl ions present in the solution to form the hydroxide , which in turn decomposes on drying to yield zirconia . Faradaic efficiencies of 20–50% were found, attributable to reduction reactions that do not produce hydroxyl ions, as well as to formation of the hydroxide at sites removed from the cathodic substrate due to diffusion of the hydroxyl ions. The effects of current density, time, and hydrodynamic conditions on coating weight, cell voltage, temperature, and pH of the solution were studied.read more

Cathodic electrodeposition of ceramic and organoceramic materials. Fundamental aspects
TL;DR: In this article, a review of recent developments in the electrodeposition of ceramics and organoceramic materials is presented, which includes mass transport, accumulation of particles near the electrode and their coagulation to form a cathodic deposit, and interparticle forces that govern colloidal stability in the absence and presence of processing additives.
