Review on CeO2-Based Corrosion Coatings

Abstract

Cerium oxide (CeO2) nanoparticles have emerged as a significant nanomaterial in a wide range of applications, including photocataly sis, corrosion inhibitors, and biological applications. T he corrosion resistance hy brid film based on CeO 2 nanoparticles turns into a more remarkable inhibitor than hazardous chromate-based protective materials. In this review, we present the impact of CeO2 nanoparticles on corrosion protective properties; synthesis of CeO2 nanoparticles by a green and chemical process; protective CeO2 coating deposited on the substrate by different methods; CeO2-based orga nic coa tings; CeO2-based in organi c coa tings and tribological behavior of CeO2. Also, it enlightens the influence of grain size, cracking, pore size, microstructure, and micro-hardness on CeO2-based corrosion coatings. Investigations into the effects of corrosion found that CeO2-based coatings had high potential and a drop in current densities, which are responsible for the inhibitory performance. Additionally, the inclusion of CeO2 nanoparticles results in finer-grained deposits with improved corrosion resistance. M ost CeO2 coatings display good corrosion resistance compared to other potential organic and inorganic composite coatings addressed in this section. GRAPHICAL ABSTRACT
