“…Dip-coating is a time-saving and low-cost method for preparation of ceramic coatings [58,59]. In 2017, Yu et al produced a chemically robust and corrosion resistant Na 2 SiO 3 /Al 2 O 3 composite coating on the surface of the 304 stainless steel, on which Na 2 SiO 3 was incorporated into the nanopore of porous alumina layer by dip-coating heat treatment [60].…”

Surface coating can allow the bulk materials to remain unchanged, while the surface functionality is engineered to afford a more wanted characteristic. Ceramic coatings are considered as ideal coatings on metal which can significantly improve the surface properties of metal materials including anti-fouling, self-cleaning, corrosion resistance, wear resistance, oil/water separation and biocompatibility. Furthermore, various techniques have been utilized to fabricate a range of different ceramic coatings with more desirable properties on metal materials, which make the materials widely used in service environment. This chapter focus will be on the types, fabrication methods, surface properties and applications of ceramics coated metal materials.

“…Cerium oxide (CeO 2 ) also called ceria is a promising compound for several technological applications mainly because its physical and chemical properties are easily modified through a control over the composition, type of structure, morphology, and size of the particles during its synthesis and process 1,2 . Some of the essential properties of this material are oxygen storage capacity, redox potential, thermal stability, chemical stability, low toxicity, electronic conductivity, and high oxygen mobility [3][4][5] .…”

The study presents CeO 2 particles synthesized by the microwave-assisted hydrothermal method using different synthesis times for the analysis of sensitivity to carbon monoxide gas, aiming at its application as a sensor material to prevent poisoning caused by this highly toxic gas. Structural, morphological and spectroscopic and electrical behaviors were analyzed by X-ray diffraction, Rietveld refinement, transmission electronic microscopy, Raman scattering spectroscopy, optoelectronic characterization chamber and FT-IR. The samples presented fluorite-type cubic structures, increase in crystallinity and particle size with the variation synthesis time from 5 to 8 minutes. From the micrographs it was observed that the nanoparticles initially were spherical with a surface domain (200), and the synthesis time made them cubic/polyhedral with a surface (111), showing differences in defects and influencing in its properties. The sample synthesized at 8 minutes showed the best result with response and recovery time of 16 and 2 seconds, respectively, at 390 °C, therefore promising for the fabrication of CO gas selective sensing device.
