“…It is known from the literature that the morphology of the substrate [120] plays a leading role in the cold spray deposition process for metals [121,122]. These considerations were proved to be valid also for polymer-based substrates.…”

Cold spray deposition, which can be framed in the wider family of additive manufacturing, is a manufacturing technique that is able to produce coatings on diverse types of substrates through the deposition of feedstock powder. As a low-temperature process, cold spray represents a potential solution for the metallization of temperature-sensitive materials, i.e. polymers and polymer matrix composites. The study of the cold spray technology for the metallization of polymers is still in its early stage, and the deposition mechanisms of metals on polymer-based materials are not thoroughly understood yet. On these premises, a review on this topic is needed to systematically depict the actual state of the art and to provide a reliable and well-organized overview discussing all the theories arisen in these years. In summary, this review aims: i) to collect all the available literature and enucleate the most discussed and interesting points (the most prevailing theories regarding the bonding mechanisms, the influence of the different process parameters and the main characteristics of cold-sprayed coating), providing a reliable and well-organized state of the art; ii) to define the open questions and to delineate the directions of future work.

“…In addition, the in-situ usage of the laser process is not attainable. Compact plasma and cold spray process, especially in its low-pressure configuration, in contrast, are opening new scenarios for their use in solar application [54][55][56][57]. Sevillano et al [48] explored the deposition of Ni-alumina cermet to produce coatings for solar power generation.…”

Solar power is a sustainable and affordable source of energy, and has gained interest from academies, companies, and government institutions as a potential and efficient alternative for next-generation energy production. To promote the penetration of solar power in the energy market, solar-generated electricity needs to be cost-competitive with fossil fuels and other renewables. Development of new materials for solar absorbers able to collect a higher fraction of solar radiation and work at higher temperatures, together with improved design of thermal energy storage systems and components, have been addressed as strategies for increasing the efficiency of solar power plants, offering dispatchable energy and adapting the electricity production to the curve demand. Manufacturing of concentrating solar power components greatly affects their performance and durability and, thus, the global efficiency of solar power plants. The development of viable, sustainable, and efficient manufacturing procedures and processes became key aspects within the breakthrough strategies of solar power technologies. This paper provides an outlook on the application of thermal spray processes to produce selective solar absorbing coatings in solar tower receivers and high-temperature protective barriers as strategies to mitigate the corrosion of concentrating solar power and thermal energy storage components when exposed to aggressive media during service life.

“…The surface barrier layer that was obtained by post laser treatment had low porosity [115, 116] with few interconnected pores, which improves the corrosion resistance, in a manner comparable to that of bulk Ti [117]. A thermo-mechanical numerical model has been built to simulate the laser treatment effect on CSAMed deposit on Al substrate [118]. The temperature distribution and microstructures produced by laser post-treatment are shown in Figure 36 [119].…”

Cold spray (CS) is a new solid state coating technique that has attracted considerable attention as it is quite suitable for mass production of metallic materials or metal matrix composites. More recently, cold spray additive manufacturing (CSAM) has been proposed to fabricate/repair components or produce welding joint. However, inherently deficient in ductility/plasticity of CSAMed materials limits its application. Therefore, many hybrid processes have been proposed to further explore CS, which can be grouped together as 'cold spray +' hybrid processes (laser, shot peening and friction stir processing). This review will summarise the state-of-the-art of the 'cold spray +' processes to show their abilities and their effectiveness. Recommendations for further research and development have been incorporated to help widespread the process.
