“…Ranand et al studied Ti-TiB 2 nanocomposite coatings using dual-cathode magnetron sputtering in Ar onto polished titanium and silicon substrates. Ti-TiB 2 nanocomposite coatings exhibited a flatter hardness-toughness relationship compared with metal carbide-DLC and TiN-Si 3 N 4 nanocomposite coatings, since the formation of coherent Ti-TiB 2 interfaces, which produced stress fields activating the motion of nearby dislocations within the Ti matrix and hence improved fracture toughness [37]. Movahedi reported the NiAl-15 wt% (Al 2 O 3 -13% TiO 2 ) nanocomposite coating was tougher and harder than the NiAl intermetallic coating.…”

Abrasive resistant coatings have been widely used to reduce or eliminate wear, extending the lifetime of products. Abrasive resistant coatings can also be used in certain environments unsuitable for lubrications. Moreover, abrasive resistant coatings have been employed to strengthen mechanical properties, such as hardness and toughness. Given recently rapid development in abrasive resistant coatings, this paper provides a review of major types of abrasive coatings, their wearing mechanisms, preparation methods, and properties.

“…24 In this case, it is believed that the matrix carries the compressive force while the dispersed particles obstruct the dislocation motion. It also should be noted that based on results from Gül et al 25 Also, according to Ranade et al, 26 the formation of coherent matrix-nanoparticle interfaces produce stress fields activating the motion of nearby dislocations within the matrix, and improves mechanical property. Weiwei et al 6 also have reported that introducing nanoparticles by adding the solution can effectively avoid particle agglomeration, therefore significantly improving the particle dispersion strengthening effect explained by Orowan mechanism.…”

Ni-B/SiO 2 , Al 2 O 3 , TiO 2 and CuO composite coatings were successfully obtained by the electroless plating technique. Dispersible SiO 2 , Al 2 O 3 , TiO 2 and CuO nanoparticles were co-deposited with electroless Ni-B coating onto AISI-304 steel substrates. Deposits were characterized for its structural properties by X-ray diffraction (XRD). XRD results showed a broad peak of Ni-B and low intensity composite nanoparticle peaks. The surface and cross-section morphology of samples were analysed using a scanning electron microscope (SEM). Surface analysis showed that the incorporation in Ni-B matrix of nano-SiO 2 , Al 2 O 3 , TiO 2 and CuO particles increases the nodularity of composite coatings. The deposits are composed of a columnar structure grown along the vertical direction of the substrate surface. The results also show that electroless nanocomposite coatings tend to have greater microhardness compared with the coating without nanoparticles. The increase in the microhardness of the nanocomposite coatings reported in this study is attributed to an effect of dispersion strengthening of ceramic particles in the Ni-B matrix.

“…However, the strength and failure mechanisms of the interface between the two different phases also represent important factors when studying the mechanical properties of these composites. In this regard, studies have demonstrated that the enhanced toughness of these TMN composites is facilitated via various phenomena occurring at the interface, such as crack deflection, stress relaxation, and energy dissipation [4][5][6][7][8]. Therefore, obtaining detailed information regarding the interfacial characteristics is imperative for developing advanced metal/TMN composites with optimal mechanical properties.…”

Obtaining detailed information regarding the interfacial characteristics of metal/hexagonal-TMN composites is imperative for developing these materials with optimal mechanical properties. To this end, we systematically investigate the work of adhesion, fracture toughness, and interfacial stability of M/Cr2N and M/V2N interfaces using first-principles calculations. The orientation (0001) of hexagonal phases and (111) of fcc phases are selected as the interface orientations. Accordingly, we construct M/Cr2N interface models by considering 1N, 2N, and Cr terminations of Cr2N(0001), as well as two stacking sequences (top and hollow sites) for the 1N- and 2N-terminated interface models, respectively. The M/V2N interface models are constructed in the same way. The V-terminated Ni/V2N interface is demonstrated to provide a good combination of the work of adhesion, fracture toughness, and interfacial stability. Therefore, the Ni/V2N interface model can be regarded as the preferred configuration among the metal/hexagonal-TMN interface models considered. The present results offer a practical perspective for tailoring the interfaces in metal/hexagonal-TMN composite materials to obtain improved mechanical properties.
