“…Similar results were obtained by Lupoi et al [82], who analysed the deposition on thermoplastic and thermosetting substrates under the same spraying conditions. The copper powders were cold-sprayed on high-density polyethylene (HDPE) and polytetrafluoroethylene (PTFE), which are thermoplastic and thermosetting polymers, respectively, as shown in Fig.…”

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.

“…The ability to deposit a thick film with controlled porosity allows for the design of membranes with tailored mean pore size, effective in the removal of particulates from water. Despite the fact that the majority of anti-fouling measurements are presented in the form of paints for the reasons previously mentioned, this solution is not optimal for low surface energy thermoplastic polymers (Ref 133,144) such as the polyurethane skins on seismic streamers. Such material presents insufficient adhesion for paints and lack the negative interactions mentioned between steel and copper.…”

Beyond Traditional Coatings: A Review on Thermal-Sprayed Functional and Smart Coatings

Thermal spraying has been present for over a century, being greatly refined and optimised during this time. It has become nowadays a reliable and cost-efficient method to deposit thick coatings with a wide variety of feedstock materials and substrates. Thermal sprayed coatings have been successfully applied in fields such as aerospace or electricity production, becoming an essential component of today's industry. To overpass the traditional capabilities of those coatings, new functionalities and coherent responses are being integrated, opening the field of functional and smart coatings. The aim of this paper is to present a comprehensive review of the Advantage has been taken of a beneficial phase transformation triggered by the correspondent event (such as a crack or the tribological interactions respectively) to promote self-healing.Another approach has been the release of an encapsulated component which effectively heals the coating or provides lubrication when required. All these exciting developments pave the way for the numerous applications that are to come in the next decade, making the field of thermal sprayed coatings a unique opportunity for research and development.

“…In another investigation by King et al the spray temperature improvement from 150 ºC to 350 ºC resulted in mean particle embedding depth for the HDPE, PP, Nylon 6, PTFE, PC, and PU substrates [24]. Better polymer surface coverage was found to be provided by higher particle impact energy for the substrates HDPE and PTFE [25,26]. The low coating adhesion issue arising in case of low-pressure cold spray configurations can be averted by incorporating the interlayer materials during the CS [9,10,27].…”

Metallization is a common strategy employed to enhance the electrical and thermal conductivity of polymer matrix composite materials. Nevertheless, metallic deposition on polymer-based materials is challenging due to the inherent limitations related to high temperature exposure of the substrate. In this article, a new technique for the manufacturing of composite laminates and the subsequent metallization by cold spraying of metallic powder is presented. The composite manufacturing route is based on the production of thermoplastic-thermoset hybrid substrates and consisted of two main stages: in the first stage the partial impregnation of a reinforcement textile by a thermoplastic film was promoted by hot pressing compaction. Afterwards, the prepared lamina was vacuum bagged with other reinforcing layers and impregnated by the thermoset catalyzed resin by a vacuum infusion process. Finally, the thermoset and thermoplastic layers were co-cured to increase the adhesion of the substrate with the thermoplastic film. The metallization of composite laminate was obtained through the cold spraying technique, depositing powders on the thermoplastic surface layer. The effect of processing parameters on the coating deposition, quality and microstructure was reported and discussed.
