“…As a result, the yield strength, ultimate tensile strength and elongation of the MMC deposits were simultaneously enhanced. The samples after hot rolling displayed higher values of ultimate tensile strength (~131 MPa) and elongation (~5.2%) than the corresponding values for the as-sprayed (~37 MPa, ~0.3%) and conventionally heat treated (~60 MPa, 1.6%) samples (Figure 20f) [88]. In addition to the above work, the same research group has also applied hot rolling on cold sprayed Si/A380 MMC deposits [89].…”

“…Apart from the above-mentioned post process treatment methods, there are also some other means, which will be reviewed in this section (as summarized in Table 6). Hot rolling is a thermo-mechanical treatment process in which metal is heated above the recrystallization temperature and plastically deformed in a rolling operation [88] (Figure 20a). Tariq et al [88] conducted a study on the effect of post hot rolling on cold sprayed B 4 C/Al MMC deposits.…”

Cold Gas Dynamic Spray or Supersonic Cold Spray, or simply ‘Cold Spray’, is an emerging technology for rapidly building thin films, thick coatings and large-scale additive manufacturing at relatively low temperatures. In a cold spray process, particles are accelerated to supersonic speeds by a propellant gas and impact a substrate, thus producing a strong bonding with the substrate and subsequently forming a deposit via layer-by-layer buildup. The scalability and low cost of this method make it promising for many applications in industry, such as metal component surface repair/enhancement/restoration and functional coatings for electrical, thermal, biomedical, energy storage, and nuclear plant applications. However, cold sprayed deposits usually require post process treatments to further modify their microstructures and mechanical properties in order to obtain the desired performances. A number of studies have been carried out on this topic. Here, recent progress in different post process treatments on cold sprayed deposits is reviewed, including heat treatment, friction-stir processing, shot peening, and laser re-melting. The effects of these post treatments on the microstructure, residual stress and mechanical properties of cold sprayed deposits are discussed.
