| Abstract |
| Cerium oxide (CeO2) nanoparticles have emerged as a significant nanomaterial in a
wide range of applications, including photocatalysis, corrosion inhibitors, and
biological applications. The corrosion resistance hybrid film based on CeO2
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 organic coatings; CeO2-based inorganic coatings 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. Most CeO2 coatings display good
corrosion resistance compared to other potential organic and inorganic composite
coatings addressed in this section.
