Preparation of Cerium Dioxide Layers on Titanium by Electrodeposition with Organic Solution

Abstract

Layers of cerium dioxide nanoparticles were prepared on titanium by electrodeposition with organic solution. Three concentrations of cerium ions were used at 31.6 V. The organic solution was isobutanol and titanium foils were used as anodes and cathodes. Currents were monitored during the electrodeposition. Deposition times ranged from 0.5 to 8 h. Deposited Deposited layers were calcined at 700 K for 30 min. The morphology and composition of the deposited layers were examined by scanning electron microscopy (SEM), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). As-prepared and calcined deposition layers were assayed to be cerium dioxide. The average crystallite size increased from 4 to 7 nm through calcination at 700 K. Sizes of calcined cerium oxide agglomerates were ranging from 73 to 146 nm for 30 min deposition and 209 to 262 nm for 8 h deposition. The electrodeposition efficiencies of 0.5 h deposition at three concentrations were measured to be highest.

Cerium dioxide modified with fumaric acid as corrosion inhibitor for epoxy coatings on Q235

“…The XRD patterns of fumaric acid, CeO 2 and CeO 2 -f with the characteristic peaks and corresponded reflection planes are presented in Figure 2. The characteristic peaks of CeO 2 at 28.61°, 33.13°, 47.61° and 59.49° (2 θ ) were assigned to the planes of (111), (200), (220) and (311), respectively (Nande et al , 2017). The pattern of CeO 2 -f shows the main peaks of CeO 2 , as well as the characteristic peak of fumaric acid.…”
