“…The underlying mechanisms that govern the material deposition are further explored by analyzing the FE simulation results discussed next. Finally, it is noteworthy to mention that the grid-like patterns observed in the remnant nylon-6 particles on the composite substrate after separation (Figure b) are likely a direct result of the fiber weave structure inside the epoxy matrix, discussed in Anni et al…”

“…The research leading to this article expanded the existing knowledge of cold spray as an additive manufacturing process for coating and repair of fiber-reinforced polymers (e.g., see ref 49 for more details regarding the potential application of polymer cold spray as a composite repair process). Comparing the results of the present work to the existing literature, several improvements and novel insights were identified.…”

This work investigates the cold spray deposition of thermoplastic powders on fiber-reinforced polymer−matrix composites using a combined experimental-computational approach. Cold spray deposition of nylon-6 powders on woven glass fiber-reinforced composite panels is successfully achieved by the proper identification of two critical process parameters, particle temperature and impact velocity. Experimental evaluations indicate that the bonding between the deposited nylon layers and the composite substrate is achieved primarily due to the concurrent severe plastic deformation of the powders and the surface epoxy layer on the substrate, leading to the development of acceptable bond strengths. Finite element simulations reveal the fundamental impact mechanics of the process while ensuring that the impact-induced damage to the reinforcing fibers can be minimal, provided that the cold spray process parameters are selected properly. Results presented herein highlight polymer cold spray as a promising surface coating and functionalization process applicable to polymer−matrix composites.

“…It should be noted that when implementing such an operational property of materials as their wear resistance, the task is complicated due to the significant dependence of stresses on the ratio of constituent polymermetallic materials, sizes, shapes of their constituents, as well as structural features of conjugated parts and properties of the working (technological) environment [6,7] .…”

For the conjugation of samples and parts of the "shaft-sleeve" type, from the theoretical and experimental points of view, the laws of the change of the coefficient of friction for the combined polymer-metal material and coating were considered. Based on the law of energy conservation and transformation in the friction zone, expressions for estimating friction coefficients for polymer coatings and combined polymer-metal materials were obtained, taking into account the properties of thermal conductivity and elasticity and the geometric dimensions of the polymer and metal components. The consistency of the patterns of change in the friction coefficient has been clarified in tribocouplings of samples and parts from load and sliding speed in modes without lubrication and at extreme friction. To substantiate the effective operation of tribocoupling of parts made of combined polymer-metal materials, a criterion was introduced - the coefficient of wear, which is used to evaluate the tribological efficiency. It is shown that the obtained experimental results do not contradict the theoretical justification

“…Materials exhibiting ductile behavior are better suited for coating on substrates such as carbon fiber reinforced composites [17]. The cold spray approach involved depositing thermoplastic particles onto fiber reinforced polymer composites, effectively protecting the substrate without causing any major damage [18]. The application of the composite coating resulted in improvements in both the morphology and structure of the composite material, leading to enhanced material properties.…”

Additive manufacturing has witnessed an upward trend in utilization across diverse industries in recent years. This study examines the tribological properties of polymer composites produced using additive manufacturing. The polymer composites were produced using the fusion deposition modeling process. Subsequently, they undergo thermal spray coating and spin coating processes that deposit hafnium carbide particles onto their surface. The wear test studies were conducted at three distinct temperature levels in accordance with the ASTM standard procedure. The findings demonstrated that the application of a ceramic particle coating led to a substantial decrease in the specific wear rates. Additionally, there were observed differences in the wear rates depending on the specific methods used for applying the coating. The application of thermal coating shown high efficacy in reducing wear rates and safeguarding the underlying materials against material loss. The uncoated PLA-CF material showed a slightly significant amount of material degradation as the test chamber temperature increased, in comparison to the coated specimens. The average specific wear rate of the thermally coated PLA-CF specimen at a temperature of 70˚C is 0.000156 kg/Nm.
