OBRABOTKAMETALLOV MATERIAL SCIENCE Vol. 27 No. 1 2025 indicating a predominantly amorphous structure of the base material. The absence of observable crystalline domains suggests that the material is specifically designed for applications requiring flexibility and impact resistance, which are often associated with amorphous polymers. EDS Analysis and Elemental Composition The results of EDS analysis for the base Acrylate material are presented in Figs. 7, a and 7, b. The EDS investigation enabled quantitative determination of the elemental composition of the base material, revealing that it primarily consists of carbon (C) and oxygen (O). In one region, the elemental composition was determined to be approximately 71.17 wt. % carbon and approximately 28.83 wt .% oxygen; in another region, approximately 72.21 wt. % carbon and approximately 27.79 wt. % oxygen. The composition of substances was determined as 76.68 wt. % carbon and 23.32 wt. % oxygen, and 77.59 wt. % carbon and 22.41 wt. % oxygen, respectively. a b c Fig. 6.

EDS analysis for base Acrylate material: a – spectrum with 70 µm; b – EDS graph for 70 µm Spectrum The high carbon content is a characteristic feature of polymer materials, in which carbon plays the role of the primary structural element, as also shown in Fig. 7, b. The detected oxygen is likely associated with the presence of functional groups such as carbonyl (C=O) or ether (C-O-C) groups, which are characteristic of polymers, such as PEEK (polyetheretherketone). These groups contribute to enhanced thermal stability and chemical resistance of the material, improving its performance characteristics in demanding applications.
