PEEK can be used for diverse applications, including bearings, piston parts, base plates for a conductive coating, or medical orthopedic implants, using the benefits of surface metallic functionalization. In this paper, we investigate the capability of tuning cold spraying parameters along with operating conditions to achieve a high DE and examine the best electrical conductivity coatings on PEEK. Thus, parametric analysis, along with the deposition optimization, promises to be feasible for the future in terms of DE improvement along with a good electrical conductivity in CS. The results reveal that the Cu coating on PEEK reaches a DE up to 91%, leading to an electrical conductivity up to 60% IACS (International Annealed Copper Standard). A nozzle scanning velocity in the range of 200–300 mm/s gives the highest DE. A good coating formation up to 400 µm can be obtained, which implies that a standoff distance higher than 100 mm is needed, since both a high gas temperature (400–500 ☌) and high gas pressure (30 bars) are required. The additive principle is obtained using the high-pressure cold spraying (CS) method whose literature does not include an achievement as suggested in this paper, that is, to obtain a good conductive copper coating onto polymer with a very high deposition efficiency by tuning the effect of the stand-off distance, transverse speed of the nozzle, and temperature of the carrier gas on the deposition efficiency (DE) in order to overcome delamination and erosion, and thus to improve the DE. We investigate the suitability of such a principle to easily and efficiently grow a metallic electrically conductive coating on a polymer substrate. ![]() With a bit of luck, players may see their achievement unlock.This paper investigates a current challenge that enables the hybridization of different materials using a solid-state additive principle. Players should keep an eye out for pinball flippers, projectiles, large swinging hammers, and must be willing to risk elimination by allowing these obstacles to fling them off the map. In particular, most levels with fast-moving obstacles can be used, as these obstacles can launch players far distances. ![]() There are plenty of other levels where Fall Throttle can be unlocked. Now, it is entirely luck-based whether or not Airtime comes up in an episode, so some players may not want to rely entirely on it. ![]()
