“…The antibiotic-containing CaPO 4 deposits were found to exhibit significant in vivo improvement in preventing infection compared with the standard ones [934,943,944]. Similar effect was found for Ag-doped deposits [701][702][703][704][705][706][707][708]. These delivery methods of bioactive molecules extend the functions of CaPO 4 deposits to enhance new bone formation on orthopedic implants.…”

Cold spraying – A materials perspective

Cold spraying is a solid-state powder deposition process with several unique characteristics, allowing production of coatings or bulk components from a wide range of materials. The process has attracted much attention from academia and industry over the past two decades.The technical interest in cold spraying is twofold: first as a coating process for applications in surface technology, and second as a solid-state additive manufacturing process, offering an alternative to selective laser melting or electron beam melting methods. Moreover, cold spraying can be used to study materials behaviour under extremely high strain rates, high pressures and high cooling rates. The cold spraying process is thus considered to be relevant for various industrial applications, as well as for fundamental studies in materials science.This article aims to provide an overview of the cold spray process, the current understanding of the deposition mechanisms, and the related models and experiments, from a materials science perspective. IntroductionCold spraying (CS) is a solid-state material deposition technique, where micron-sized particles of a powder bond to a substrate as a result of high-velocity impact and the associated severe plastic deformation. Acceleration of particles to high velocities is obtained via expansion of a pressurised and (ironically) 'hot' gas through a diverging-converging nozzle.Despite heating the process gas -which is to provide higher acceleration of the gas and also to facilitate particle deformation through thermal softening -the feedstock remains in the solid state throughout the entire process; hence the name 'cold' spraying. This is to underline the contrast to conventional thermal spraying where particles are completely or partially molten upon impact onto the substrate. Alternative terminology includes cold gas spray, micro cold spray, cold gas dynamic spray, kinetic spray, supersonic particle deposition and metal powder application (MPA), all of which refer to the same principle of solid-state powder deposition as described above. CS is used for coating and repair. It is also used for additive manufacturing (AM) at relatively high deposition rates as compared to the methods based on selective laser or electron beam melting. The main advantage of CS is that it alleviates the problems associated with high temperature processing of materials, such as oxidation and unfavourable structural changes. It is possibly the only continuous method to produce bulk components of metastable materials that are available only in the powder form, e.g. as obtained from mechanical attrition or gas atomisation. The aim of the present paper is to provide an overview of CS from a materials perspective, particularly for a broader audience in materials research, e.g. with interest in dynamic phenomena, plasticity and phase transformations. In terms of application and properties, CS is perhaps best to be compared to thermal spraying processes, as in [24,25]. In view of relevant physical phenomena, however, CS is mos...

“…In photovoltaic applications, cold spray could be used for the fabrication of complex conductive patterns in solar cells [9,10]. In the medical field, cold spray has already been demonstrated to effectively make hydroxyapatite composite coatings on some substrates [11,12].

Cold spray technology, originated from the Institute of Theoretical and Applied Mechanics Siberian branch of the Russian Academy of Sciences, is a rapidly emerging industrial coating technology. Cold sprayed particles with high-velocity impact onto a substrate so as to induce severe plastic deformation and then create a deposit. For its low temperature and high velocity compared with thermal spraying, the cold spraying process is increasingly used in the industries for protective coating. The deposition characteristics of the particles, coating formation and bonding mechanism of the cold spraying process are different from thermal spraying. Many theory investigations of the cold spraying process contribute to the development of the high performance coatings, which makes the cold spraying process as a popular research field. Presently, the deposition characteristics, bonding mechanism, process optimization as well as classical applications of the cold spraying technology in the past are reviewed, and the interesting points for the further development, optimization and applications of this technology are also recommended. cold spray, deposition, coating, bond mechanism, application Citation: Wu X K, Zhang J S, Zhou X L, et al.
