The paper aims to investigate the behavior of PLA and HD PLA Green biopolymer samples coated with bronze composite powder, Metco 51F-NS (Bronze Alloy – Cu 9.5Al 1.2Fe – nominal composition). The coated samples were obtained by 3D printing (FDM method) and the micro powder deposition was achieved using the Atmospheric plasma spray (APS) deposition. The following determinations were conducted: structural, morphological analysis, and Dynamic Mechanical Analysis (DMA) to demonstrate the good adhesion of the coating layer and implicitly improve the surface characteristics of the studied biodegradable polymers. The novelty of this study is given by itself the coating of the biodegradable biopolymer (as substrates) with bronze composite microparticles. Following the study, the increase in the samples' mechanic-dynamical characteristics recommends it as suitable for operating in harsh conditions, such as the automotive industry to replace nonbiodegradable materials.
