“…Therefore, the aim of this work was to produce the FeAl intermetallics deposit by cold spraying of a Fe/Al powder mixture followed by heat-treatment. A few papers published on cold-spraying of metal powder mixtures (W/Cu [17], Zn/Al [18], Ti/Al [16] and Ni/Al [19]) show that dense composites can be produced using mixed powder and the heat treatment may lead to the intermetallic phases formation. However, there are no reports focusing on the characterization of cold sprayed Fe/Al composite deposit and its phase transformation during heat treatment.…”

“…Cold spray coatings with attractive properties have been obtained in the case of pure metals such as Cu, Al, Ti, Ni, Fe, and Ta (Ref [1][2][3][4][5][6][7][8][9] and also in the case of metallic alloys such as stainless steels, Inconel, Ni-Cr alloys, Ti-6Al-4V, and steels (Ref [10][11][12][13][14][15][16][17]. In all these coatings, the coating property and its performance are substantially influenced by the extent of bonding between the splats (powder particles which flatten on impacting the substrate are defined as splats) that make up the coating.…”

The quality and performance of cold spray coatings are largely determined by the extent and strength of bonding between the adjacent splats. Usually, the extent of inter-splat bonding is only qualitatively estimated by examining the polished and etched sectioned surfaces of the coated sample. Thus, there is a clear need for indirect techniques to quantitatively estimate the extent of inter-splat bonding so that they can serve as quality control tools. In this study, elastic modulus, electrical conductivity, and critical load for inter-splat debonding as determined using a scratch test are considered as possible parameters for the estimation of the extent of inter-splat bonding using four different cold spray coatings (Ag, Cu, 316 Stainless Steel, and Zn) as model coatings. It is demonstrated that all the three parameters are capable of quantifying the extent of inter-splat bonding.

“…During the time interval, an intermetallic reaction was occurring. We note that in papers [3] and [4] the similar way was used to obtain Ni-Al and Fe-Al intermetallic compounds. The advantage of the way is obtaining of large areas of surfaces hardened by intermetallic compounds.…”

Investigation of the microstructure of Ni and B 4 C ceramic-metal mixtures obtained by cold spray coating and followed by laser cladding AIP Conference Proceedings 1893, 030019 (2017) Abstract. The results of the experiment and numerical simulation of Ti-Al intermetallic compound synthesis using cold gas-dynamic spraying and heat postprocessing in an oven at a temperature above the aluminum melting temperature are presented. Ti-Al-type intermetallic systems were obtained at heating temperatures from 930 to 1620 K and phase composition and crystal structure of the compounds were studied. Numerical simulation of the intermetallic synthesis process performed by the molecular dynamics method had shown that the kinetics of the process at these temperatures is determined by the diffusion and dissolution processes of titanium in molten aluminum.
