Examination of the Internal Surface of a Firing Chamber of Armament Elements

The study focuses on analyzing the interior surfaces of the component responsible for directing projectiles during discharge. This investigation involves a detailed assessment of the chamber's internal condition, aiming to uncover any signs of wear, erosion, or deformation that could impact performance and safety of use. In the study, results from surface analysis of cut fragments taken from eight selected locations of the examined object were utilized. The samples were scanned using the ATOS Compact Scan 5M portable 3D scanner. Subsequently, a geometric model of the sample’s surface was created using CAD software and compared with the scan data through ATOS Professional software. The resulting surface maps enabled the evaluation of the scale of erosion on the sample surfaces and facilitated the analysis of the destructive mechanisms occurring during the object’s operation. Surface roughness measurements were conducted on 2x2 mm areas of the samples using a Hommel-Etamic T8000RC stationary profilometer. According to ISO 25178, three-dimensional surface maps were obtained, allowing for a detailed description of surfaces condition and the mechanisms occurring at the analyzed areas . The evaluation employs advanced imaging SEM, EDS and measurement techniques to ensure a comprehensive understanding of the structural integrity and functional state of this crucial element in the armament assembly.
