“…The second set of specimens was produced with the same process parameters and deposition strategy and with a double pass of the spray gun for the coating grow-up. A second pass may increase the continuity and the thickness of the coating, however, the upcoming particles may lead to a detachment of the first layer of the coating as proved in literature [26,27]. The reason is that the anchorage energy between the first layer and the polymeric substrate is smaller than the energy required by the second layer to adhere on the first one.…”

Polymer matrix composites are finding never-ending widespread uses in the last decades; one recent tendency is to metallize their surface to further widen their field of application. Cold-spray deposition is one of the most promising techniques that can be adopted to this aim. Cold-spray deposition on polymers is in its early stage and more experimental work is required to fully understand the phenomena ruling the deposition. In this paper, the results of nanoindentation measurements on cold-spray coatings on various substrates will be presented and discussed. Polypropylene was used as matrix while carbon and glass fibers have been used as reinforcement, both steel and aluminum have been used as feedstock material for the cold-spray deposition. Nanoindentations tests have been then carried out on all the different samples; the influence of the fibers and of the powders sprayed on the behavior of the coatings is discussed in light of the experimental outcomes.

“…Even with less impact energy, deformation of the particle is still necessary during the collision. Therefore, only a polymeric substrate that is softer and more ductile, like thermoplastic materials, can allow for the deposition of CS metal and the formation of coatings [12].…”

“…However, thermosetting matrix composites are the most appealing in many industries (including automotive and aerospace) due to their high compatibility with fibres and strong mechanical properties. To address this issue, it was presented a unique method that may consist of putting a thermoplastic-based interlayer on the surface of a thermoset-based substrate to achieve excellent CS deposition [12].…”

Abstract. Cold spray is a recently developed manufacturing technology for creating metallic layers on a variety of materials. Metallic particles are accelerated and strike the target surface using a pressurized gas flowing at supersonic speeds. In the last years, cold spray has gained increasing interest in different industrial scenarios, in particular, in the aerospace sector. Given the many fields of application, the need to understand how coated substrates behave when it is necessary to carry out machining operations arises. In this work, low-pressure cold spray equipment was employed to produce metal coatings on epoxy-based glass fibre-reinforced substrates optimized for cold spray deposition employing a layer of polypropylene on the composite surface. An automatic multi-purpose machine was used to drill 4mm diameter holes in the coated specimens considering the rotational speed fixed and varying the feed rate. The machined areas were then analyzed to assess the surface quality of the drilled holes and the burr morphology, considering different feed rate values and different entry surface of the drill-bit.

“…In recent years, metallization of polymers has garnered increased interest (Ref 22 , 23 ) and some success has been obtained in depositing metallic layers on polymeric substrates with a variety of metals, e.g. tin (Ref 18 , 24 - 26 ), iron (Ref 24 ), 316L stainless steel (Ref 27 , 28 ), AlSi10Mg (Ref 28 - 30 ), copper (Ref 18 , 24 , 26 , 31 - 34 ) or aluminum (Ref 33 , 35 ). Notably, high deposition efficiencies of over 70% for copper on PEEK deposition were recently recorded (Ref 32 , 34 ).…”
