“…Metallization of polymers has received increasing attention in a wide range of applications during the past few decades (Ref 1). In the early 1990s, the evolution in microelectronics industry stimulated intensive research on this topic due to the great need for miniaturization and reduction Among these technologies, cold spray has been demonstrated to be a feasible approach to metallize polymers and polymeric composites ( Ref 3,6,7,8,9,10,11,12,13). In particular, cold spray features low processing temperatures, which will minimize the thermal damage to the polymeric substrates compared to other thermal spray technologies.…”

Cold spray has been proven to be a viable method for metallization of polymers and polymer composites, although it has been reported that the mechanism of cold spray on polymeric substrates is different from the mechanism on metallic substrates. In this work, single copper particle impact experiments were performed on polymeric substrates as well as mild steel. Two gas temperatures were selected for each polymer substrate, with one leading to a particle temperature above the glass transition temperature when reaching the substrate and the other below. The particle-substrate interactions on different substrates were analyzed. Based on the results, the mechanism of cold spray on polymeric substrates is discussed and compared to that on metallic substrates.

“…In order to work with LDS method, usable plastics for LDS required specific additives such as Cu 2 O, CuO or CuCl 2 , which can be added in a very high concentration to the blend during compounding step. The characteristic of these additives is extreme heat resistance and great potential to prevent nucleation during injection molding process [ 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 ]. However, it is also possible to prepare plastics for LDS without specific additives.…”

“…LDS is based on the principle of ablation and nucleation by using laser irradiation. Therefore, the laser patterning creates a microscopically rough surface and simultaneously activates the specific additives that are necessary for the metallization step [ 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 ]. The schematic of LDS method is illustrated in Figure 1 .…”

The three-dimensional molded interconnected device (3D-MID) has received considerable attention because of the growing demand for greater functionality and miniaturization of electronic parts. Polymer based composite are the primary choice to be used as substrate. These materials enable flexibility in production from macro to micro-MID products, high fracture toughness when subjected to mechanical loading, and they are lightweight. This survey proposes a detailed review of different types of 3D-MID modules, also presents the requirement criteria for manufacture a polymer substrate and the main surface modification techniques used to enhance the polymer substrate. The findings presented here allow to fundamentally understand the concept of 3D-MID, which can be used to manufacture a novel polymer composite substrate.

“…The CS process accelerates metal particles through high-temperature and high-pressure airflow to supersonic speed. The high-speed particles impact the substrate and deform with a high-strain rate, which makes the particles form a metallurgical bond or mechanical bond with the substrate [6,7]. The mechanisms involved with CS include adiabatic shear instability [8].…”

“…The ns laser can also induce micro-textures on the substrate, and these structures are suitable to improving the bonding strength between the particles and the substrate. Kromer [7] used the ns laser to induce the microstructure to improve the processing deposition efficiency and interface bonding strength. Danlos [16] proposed the ns pulsed laser ablation and ms pulsed laser heat treatment of the 2017 aluminum alloy substrate before cold spraying.…”

In this study, nanosecond-pulse laser is used in combination with cold spraying to form a hybrid solid-state forming technology: nanosecond-pulse laser assisted cold spraying. This method successfully manufactured Al-Cu high-strength aluminum alloy coatings. The nanosecond-pulse laser reduced the porosity of the coatings. The laser-induced micro-texture on the substrate surface had the ability of improving the bonding strength of the coating-substrate interface. The bonding strength was closely related to the depth of the micro-texture. The deeper micro-texture caused an unfused interface on the bottom of the texture, which produced voids and reduced the bonding strength. The nanosecond-pulse lasers can also increase the hardness of the coatings. The assistance of the nanosecond-pulse laser has proved to be an effective method to improve the quality of cold sprayed metal coatings.
