“…If the molten Fe does not immediately sink to the bottom of the molten pool during the cooling process, it is encased by the initial Al 2 O 3 crystal to solidify and become embedded in the ceramic layer. A minor amount of Fe particles may prevent the formation and expansion of cracks on the ceramic layer, limit the motion of dislocations inside the ceramic matrix, and ultimately increase the ceramic layer's strength and hardness [41]. For TiC coated samples, comparing the SWR at lower load, coated samples showed 56% and annealed samples exhibited a 60.64% reduction in the SWR compared to the substrate.…”

In the present work, a low-carbon steel substrate was coated with Al2O3 and TiC using self-propagating high temperature synthesis. The synthesized coatings were annealed at 450oC for 2-6 hrs. The characteristics of the substrate, coated, and annealed samples were examined, including microhardness, wear resistance, and corrosion resistance. A pin-on-disc tribometer was employed to conduct the wear test by varying the load, sliding velocity, and distance. The impact of these factors on the wear rate and worn surface morphology was then examined. Further, corrosion resistance was evaluated using electrochemical corrosion testing with 3.5 wt.% NaCl as electrolyte. Results showed that Al2O3 and TiC specimens annealed at 450oC for 5 hrs and 4 hrs improved the microhardness by 1.3 and 1.06 times than that of as-coated specimens respectively. The synthesized Al2O3 and TiC coatings showed an abrasive wear mechanism at higher loads and tribolayer formation was observed at higher sliding velocity and distances. The corrosion and wear resistances of the samples were found as follows: substrate< Al2O3 coated < TiC coated < Al2O3 annealed < TiC annealed. The Al2O3 and TiC ceramic coatings were found to improve wear and corrosion resistance having potential applications in cement, petrochemical, and marine industries.

“…Ceramic nanocomposites include oxides, carbides, and nitride matrices in combination with metallic or nonmetallic elements. As already mentioned, commonly used ceramic matrices are Al 2 O 3 [ 57 ], TiO 2 [ 156 ], SiC [ 51 , 157 ], SiN [ 158 ], Si 3 N 4 [ 52 , 159 ], etc., while mostly used reinforcement materials are clays [ 111 ], silica [ 57 , 160 ], metallic oxides [ 161 ], graphenes [ 159 ] etc., under the form of nanoparticles, whiskers, fibers, or nanotubes.…”

Nanocomposites are high-performance materials with exceptional characteristics that possess properties that their individual constituents, by themselves, cannot provide. They have useful applications in many fields, ranging from membrane processes to fuel cells, biomedical devices, and anti-corrosion protection. Well-tailored nanocomposites are promising materials for anti-corrosion coatings on metals and alloys, exhibiting simple barrier protection or even smart auto-responsive and self-healing functionalities. Nanocomposite coatings can be prepared by using a large variety of matrices and reinforcement materials, often acting in synergy. In this context, recent advances in the preparation and characterization of corrosion-resistant nanocomposite coatings based on metallic, polymeric, and ceramic matrices, as well as the incorporation of various reinforcement materials, are reviewed. The review presents the most important materials used as matrices for nanocomposites (metals, polymers, and ceramics), the most popular fillers (nanoparticles, nanotubes, nanowires, nanorods, nanoplatelets, nanosheets, nanofilms, or nanocapsules), and their combinations. Some of the most important characteristics and applications of nanocomposite coatings, as well as the challenges for future research, are briefly discussed.
