“…Several authors [5][6] [7] have investigated cold spray materials made from these two types of polymers. Specifically, recent studies focused on metallization of PEEK, because of its applications to many aircraft structures [9] [10]. Malachowska et al [11] studied cold spray of metal onto thermoplastic polymer and the electrical behaviour of the coatings.…”

Cold spray is a promising process to coat polymers and carbon fiber-reinforced polymer (CFRP). The choice of the metal-polymer couple of materials, however, has a strong influence on coating build-up and properties. In the present work, we show that spraying mixtures of copper and polymer particles lead to composite coating. We observe that the polymer promotes coating build-up onto CFRP to the expense of the electrical conductivity of the coating as a result of its insulating properties. The present work investigates the influence of the coating microstructure on electrical conductivity. Various copper powders, with different morphologies, particle sizes and oxygen contents were mixed with a PEEK (Polyaryl-Ether-Ether-Ketone) powder. Cold spray of these powders resulted into composite coatings and we study the microstructures and electrical properties of such coatings as a function of powder characteristics and spraying parameters. A morphological model of the coating microstructure was developed to reproduce numerically microstructures in 3D. The conductivity of the coatings was measured experimentally for various copper powders. Careful selection of blends of copper and PEEK powders coupled with optimized spraying parameters led to metal-polymer coatings onto CFRP with a fairly high electrical conductivity.

“…Recent research efforts have included cold spraying as a metallization method in comparison with the conventional techniques including physical vapor deposition (PVD) [13,14], chemical vapor deposition (CVD) [15], electroless plating [16], and thermal spraying [17]. These techniques contain inherent drawbacks of higher processing temperature and requirement of deposition in a semi-molten or molten state [18]. It can present challenges when the substrate materials are polymers and polymer-based composites.…”

“…Regarding this topic, in the past decade several research efforts were conducted to attain the understanding on the bonding mechanisms involving different materials. These studies were mainly constructed by varying the different processing parameters such as nozzle configurations, traverse speed, gas temperature and pressure, and powder feed rate [18,21]. The literature evidences received from the single particle impact experimentation by Chen et al discussed mechanical interlocking to be the preliminary bonding mechanism of polymeric substrates [11,18].…”

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.

“…However, the relatively poor wettability and low adhesion of PEEK have limited its further applications. To date, a lot of modification methods have been proposed to adjust PEEK properties, such as, chemical etching 12,13 , polymerization grafting [14][15][16] , laser texturing [17][18][19] , coating, [20][21][22] and plasma treatment [23][24][25][26][27][28][29][30] . Among these methods, plasma treatment can effectively improve wettability and adhesion strength of PEEK surface while does not involve chemical agents.…”

Possessing excellent properties including good biocompatibility, high strength, and stiffness, polyether-ether-ketone (PEEK) has significant application values in medical and industrial fields. However, the relatively poor wettability and low adhesion limit its further applications. Atmospheric pressure plasma jet (APPJ) has been utilized for adjusting PEEK properties, but better hydrophilization effect and time stability after treatment are still urgently needed. In this paper, we employ a water-mixing nitrogen (N 2 H 2 O) APPJ to process PEEK, and surface wettability can be effectively improved (contact angle~18 within 2 min, distance between sample and nozzle outlet: 10 mm) without inducing obvious microstructure damages. Additionally, after storing for 40 days, the sample treated by N 2 H 2 O APPJ also possessed better wettability (~54) compared with that treated by N 2 APPJ (~65). On the basis of this lowdamage and high-efficient modification method, we perform aging experiments under different conditions (different temperatures 25, −10 C; and low vacuum condition: 50 kPa) to determine a relatively optimum storing condition for this method. The experiment results indicate that low temperature and vacuum are conducive to retaining the plasma-induced wettability (~34). The treatment method and storing conditions for PEEK presented here may facilitate the application of PEEK in various fields.
