“…The coating showed a dense microstructure with a porosity of about 1%. Pitchuka et al 18 studied the dry sliding wear behavior of Al amorphous/nanocrystalline alloy powder (Al-4.4Y-4.3Ni-0.9Co-0.35Sc (at.%)). It was found that the as-sprayed coatings exhibit higher steady state coefficient of friction (COF) of 0.55 compared to that of 0.38 for heat-treated coatings.…”

“…The oxidation, decomposition, phase transformation and grain growth of the spray materials or substrates can be avoided, allowing the deposition of phase transformation sensitive materials (e.g. nanostructured materials, [12][13][14] amorphous materials, [15][16][17][18][19] and WC-Co [20][21][22] ) and oxidation sensitive materials (e.g. Cu, 23,24 Al, 25,26 Ti 1,[27][28][29][30] ).…”

Cold spraying (CS) has been widely explored over the last decade due to its low process temperature and limited thermal effect on spray materials. As a solid-state process, the inherent deficiencies of traditional thermal spraying such as oxidation, decomposition and grain growth are avoided. This article summarizes the research work on the fabrication of composites and nanostructured coatings by the promising CS process. After a brief introduction to CS and its deposition mechanisms, the preparation methods of spray powders are classified. Different methods are appropriate for particles of various properties, and the tendency is to design composite powders by combined methods in order to create coatings with specified properties. Then the co-deposition mechanism of composite particles as well as research findings on metal-metal, metal-ceramic and metal-intermetallic composite coatings are reviewed concerning the deposition characteristics, microstructure and its relation to properties. Moreover, CS has been used to deposit a variety of nanostructured materials, including metals, metal-ceramic composites, and even ceramics, retaining their nanocrystalline nature in the coating without grain growth or phase transformation. Finally, the potential applications of CS and issues to be addressed in coating deposition are discussed.

“…Figure 8b shows that the unreinforced coating is more plastically deformed, has numerous cracks and to some extent, has a porous structure, which could affect crack propagation during the wear tests [17]. In this case, material removal occurs largely by the delamination of splats in combination with the plastic deformation, as evidenced by the fracture surface profile of the coating [18]. Significantly fewer cracks are observed in the fractured surface of the TiC-reinforced coating (Figure 8c).…”

Wear-resistant iron aluminide-based composites were coated on steel substrates with the High-Velocity Oxy-Fuel (HVOF) technique using ball milled Fe 3 Al and TiC powders as feedstock. The phase composition, microstructure, microhardness, elastic modulus and dry sliding wear performance of unreinforced Fe 3 Al and Fe 3 Al-TiC composite coatings (reinforced with 30 and 50 vol. % TiC particles) were evaluated in order to reveal the relationship between the mechanical and tribological behaviors. Compared to the unreinforced coatings, the composite coating with 30 vol. % TiC particles exhibited much greater hardness and higher elastic modulus. The increase of the elastic modulus of the composite coatings did not result in deterioration of sliding wear behavior. The addition of 50 vol. % TiC resulted in a further increase in hardness, however, both composite coatings showed the same elastic modulus. The fractured cross sectional surface of the unreinforced coating showed a weakly bonded microstructure promoting delamination in wear tests, whereas the composite fractured surface showed strong mechanical bonding between the matrix and carbide particles, leading to better cohesion. The Fe 3 Al-TiC coatings showed almost three orders of magnitude higher wear resistance under the dry sliding wear test compared to the unreinforced coatings.
