“…The successful bonding occurs through the intensive plastic deformation of solid-state particles upon high-velocity impact at a temperature below the melting point (Ref [9][10][11]. Due to the unique 'cold' feature, cold spray can minimize or eliminate the serious oxidation, phase transformations and thermal stress and can be widely applied for the fabrication of functional coatings (Ref 12), metallic matrix composites (Ref 13,14), additive manufacturing (Ref 15,16) and dimensional damage repair (Ref 17).…”

Cold spraying is a solid-state coating process and promising technique for additive manufacturing. However, questions raise about the bonding mechanism between the particles forming the coating. In this study, the strengthened peening effect is proposed as the determining factor for the formation of metallurgical bonding in cold spray additive manufacturing. Ni coatings and single splats were produced on Al substrates with different propelling gas pressures. Contrary to common understanding, no metallurgical bonding was observed in single-particle impact, even at the pressure of 3.7 MPa. However, the metallurgical bonding was observed at the full coating deposition through the existence of diffusion after heat treatment. Thus, the strengthened peening effect of subsequent particles with successive impact energy might be the determining factor for the formation of metallurgical bonding. Actually, strengthened peening effect significantly improved the coating quality through enhanced metallurgical bonding, which was proved by the increasing adhesion strength and decreasing porosity.

“…Yandouzi et al 130 mixed Al12Si (5-65 μm) and SiC (9-44 μm) powders with different ceramic contents ( Figure 3b). Li et al 94 mechanically mixed gas atomized Al2319 powder (5-63 μm) with irregular TiN powder (10-45 μm) for CS, and Yu et al 76,131 also used this method to produce Al5056-SiC composite powder. Besides metal-ceramic mixtures, some researchers mixed two or more metals for some special applications, e.g.…”

“…The adhesion strength is mostly determined by the bond between metallic particles and substrate, 88 while the cohesion strength depends on the scale of deformation as well as the intimate contact area of metallic particles in the coating. 131 The mechanical interlocking between ceramics and deformed metallic particles or the substrate can also affect in a positive way the bonding strength ( Figure 21 analysis indicated that an intimate contact is formed at the TiNp/Al5356 interface. However, some cracks and pores around the TiN particle can be found at the interface, and the bonding is still relatively weak.…”

“…However, it is difficult to fabricate high-performance PRMMC by conventional means, especially those with high volume fraction of ceramics. CS showed great potential in producing MMC coatings with metal matrices, such as Al and its alloys, 76,88,894,95,119,120,127,129,131,138,179,180,200 Ni and its alloys 91,75,[160][161][162]201 and Cu based composites, 153,167,202 155 Thermal spraying of WC-Co coatings will inevitably generate the brittle η phase and causedecarburization of WC, which severely affect their hardness and wear resistance. 20,204 A simple comparasion on the WC-Co coatings deposited by both CS and TS is made (Table 2), which is based on the work by Couto et al 22,157 205,206-209 The WC-xCo coatings fabricated by CS maintained the original phases of the particles, while the counterparts by high velocity oxy-fuel spraying (HVOF) or high velocity air-fuel spraying (HVAF) experienced decarbonization and formed hard brittle W2C, Co6W6C and Co3W3C phases, which cause the coatings to possess a higher hardness but lower toughness.…”

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.

“…It can be found that the WC particle size is not changed by the high-velocity impact of spray powder. It means that the fracture of the micro-sized and nano-zied WC particles does not occur, although it is reported that the large ceramic particles with a size of tens of micrometers are fractured during cold spraying [51][52][53].…”
